A lesson for the technician in a pre-post scan era

By Peter L. Orlando, Carquest Technical Institute/Advance Auto Parts

Pre-post scanning your customers cars? Be shop wise and understand the consequences of the outcome, as well as being service ready, if the customer says “OK, fix it!” (See scan tool report below.)

The car, a 2012 Lexus IS350C with the 2GR-FSE direct injected 3.5L engine (Figures 1, 2), was scanned during a routine service, and the shop noted two DTCs in the A/C system for the solar sensor circuit (Figure 3, highlighted in red boxes). They were “current codes,” and the technician advised the shop owner of his findings. This shop doesn’t perform any A/C service beyond basic refrigerant recovery and recycling, so they asked us to look at it.

Possible Deck - Orlando 1
Is there truly a problem with the solar sensor or its related circuits? If so, why are there no complaints about the A/C or heat from the customer? Is it possible this is normal behavior? This now becomes the quest for the shop searching for answers during a routine service. These are what I call service snags. If we are to investigate this issue, we must have a solid plan to ensure being paid for the service we are about to perform. If our exploration reveals evidence of normal A/C system behavior, what do we do then? What we don’t know can hurt us in the end.
Note: Although there were navigation DTCs, the shop didn’t concern itself with those DTCs, as they were history DTCs and not current.

Last call to register for the Automotive Software and Electronics Boot Camp

The Mobile Air Conditioning Society (MACS) Worldwide is sponsoring the Automotive Software and Electronics Boot Camp with Dr. Mark Quarto in partnership with FutureTech Auto at the MACS training center in Lansdale, PA September 16-20, 2019.

Top auto repair shops need to learn relevant new skills related to electronics, computer software writing, and coding to tackle today and tomorrow’s repair jobs.

The automotive industry has transitioned most automotive systems into the space of advanced electrical, electronics, and software controls. Additionally, hybrid/electric propulsion and ADAS technologies are requiring technicians to become creative and skilled in non-mechanical aspects of the vehicle. Even modern HVAC systems have experienced advances in power electronics with the use of high voltage electric heating, air conditioning, and heat pump components.

Dr. Quarto has addressed the need for higher level electronics training for technicians by creating the Automotive Software and Electronics Boot Camp, an intense five-day training opportunity.

How valuable is what you will learn in this class?

Hear what the students say!

Testimonial 1

Testimonial 2

Testimonial 3

Here are some examples of what you’ll learn…

  • Student Project #1

This is a sequential timing circuit that built by students in our Automotive Software & Electronics Fundamentals Boot Camp using one electronic chip to do the job.  Although this circuit is only turning on LEDs, it could be used to trigger fuel injectors, ignition coils, position or cycle a solenoid or, anything that needs to be triggered in a sequential order and at any desired time.  Several of these chips could be placed in series to do some serious counting.

This circuit could be used to count how many times an event has occurred such as an over or under voltage event, how many times a data request has been made, how many times a circuit has received a wake-up, monitor a significant number of circuits for a parasitic drain (unattended) for extended periods… the application in automotive service is almost endless.

  • Student Project #2

Have you ever wanted to monitor one or more circuits for transient noise or overvoltage, and monitor the circuits for various voltage levels, and know when any of the circuits are malfunctioning?  The students in our Automotive Software & Electronics Fundamentals Boot camp built the circuit and coded the software to monitor a circuit.  They could just as easily build the circuit to monitor 10 circuits simultaneously and monitored 10 different voltage levels.  NO SCOPE NEEDED and NO TECHNICIAN TIME NECESSARY after making circuit connections.

 These circuits could easily continually monitor circuits day or night, and can do this for long periods of time… and it will inform the technician to know which circuit caused the problem.  How fast is the detection? High nanosecond to low/mid microsecond ranges, depending on how many inputs are being monitored and how an interface circuit (if necessary) is constructed.  Quick, easy, programmable, and low cost.

  • Student Project #3

The participants in the Automotive Software & Electronics Fundamentals Boot Camp had built a Pulse-Width-Modulated (PWM) circuit to control a motor.  They had then coded it and are testing it in the video.  This project shows them how the controller creates the PWM control, how it controls power by using a motor as an example output.

By knowing more about PWM and being able to build a test circuit to interface with a vehicle system, the technician can substitute a signal to see how the Scan Tool and vehicle responds to determine course of action for repair.

Also, understanding PWM and being able to connect electronic devices/components or, build a specific circuit to them to force a circuit response, is critical for creating a quicker more analytical diagnostic analysis process.  More electronics and software understanding and knowledge = more confident diagnostics and repair.

The class is being held at MACS Worldwide headquarters 225 S Broad St Lansdale, PA 19446.

The future of cab filtration, HVAC design, and operator respiratory health

By Jeff Moredock

The case for the osha silica regulation and its impact on mobile HVAC design
“Why does the OSHA Silica regulation exist?” To protect workers from the dangerous effects of respirable crystalline silica. Silica, which comprises roughly 29% of the earth’s surface, interacts with earth-moving equipment whenever rock is crushed, abraded, or cut. According to the National Institute for Health, “Respirable crystalline silica . . . was reclassified in 1997 as a Group One carcinogen by the International Agency for Research on Cancer (IARC).” For us non-medical types, this means there is sufficient evidence suggesting respirable crystalline silica causes cancer in humans. See Figure 1.


Figure 1: This image of human lungs shows a healthy lung on right and one with silicosis on left. OSHA requires employers to protect their workers from exposure to RCA (respirable crystalline silica), tiny particles that can travel deep into workers’ lungs and cause silicosis, an incurable and sometimes deadly lung disease. Photo credit:

Silica exposure, while operating from within a machine cab, is addressed in the regulation. Specific engineering controls, which include a functioning HVAC system, continuous cab pressurization and a minimum level of filtration efficiency (95% on 0.3 to 10 µ particles e.g. MERV 16), are requirements of the regulation.

Merv 16 explained
Many mobile HVAC manufacturers and technicians are not familiar with the Minimum Efficiency Rated Value (MERV) rating system. ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) is an association that provides, among other things, a standard testing and rating system (ASHRAE 52.2) for filters produced for commercial buildings and homes. Under its rating system, the lowest efficiency filters are rated MERV 1, while the highest efficiency filters are rated MERV 16.
Why did OSHA apply a standard used for commercial building filtration to an operator cab on a piece of heavy equipment? While far from a perfect fit, the ASHRAE 52.2 testing and rating standard proved to be the best measure available. The test results show a range of particle sizes and the efficiency of the filter within each particle size range.
The National Institute for Occupational Safety and Health (NIOSH) studied cab filtration. One conclusion was, with few exceptions, that filtration used on operator cabs allowed significant concentrations of dust to aggregate in the operator cab. Up to that point, the focus of HVAC filtration was to keep large contaminants and objects off the evaporator core. The filtration acted more as a barrier to fingers, leaves, shop towels, and anything else in the operator cab that could be drawn into the recirculation system.
Filters are often not marked according to any standard rating system, and are often simply promoted as good, better, and best. In the heavy equipment industry, filtration efficiency is determined through the use of an engine filter efficiency test. This test standard produces an efficiency rating based on testing with ISO fine or course test dust, and includes the dust holding capacity of the filter.
Engines require efficient air filtration to keep dust from entering the engine, contaminating the oil, and causing engine wear. When the engine oil gets contaminated it is changed. Human lungs, on the other hand, are negatively affected by small particles and are not easy to change or clean. Therefore, the efficiency of the filter had to improve dramatically to be effective in protecting the machine operator. This necessitated a change in filter testing standards to ensure that the filter is efficient enough for human respiratory environments.

All about truck and off road mobile A/C

So where do we go from here?

That is the question.  There aren’t a whole lot of new things we can do with an air conditioning system to improve how it works.  Oh, there are some incremental things to enhance efficiencies, but no wholesale changes in how we get the cabin cooled that will make anyone’s life a whole lot better.  We are working with new refrigerants that have the promise to improve the global climatic effects, while maintaining the operational abilities of the systems.  We are adding small system advances to help with the, possibly, lower efficiencies of the new refrigerants, which should maintain the standard of performance we are used to.

So, once again, where do we go from here?  Read this article   Download the July/August issue

The future is electric!

June ACTION 2019

Hybrid and electric vehicle air conditioning compressor hardware, power controls and diagnostics

For more than 15 years, hybrid and electric vehicles have been using electric air conditioning compressors.  The reason for the use of these air conditioning (A/C) compressors is rooted in the stop-start operation of the hybrid vehicle, or in the fact that an electric vehicle has no engine to rotate an A/C compressor.  Read the whole article Download the magazine

Finding yf (2019 Refrigerant Update)

By Steve Schaeber, MACS Technical Editor (May 20, 2019)

©2019 Mobile Air Conditioning Society Worldwide

As part of our continuing effort to document the industry’s changeover to R-1234yf, MACS once again attended the Philadelphia Auto Show to see the new models, open a few (actually all of the) hoods, and see what refrigerant is being used. This year we skipped a few brands we knew had already changed, and scoped out those we had missed in previous years, as well as some we were really curious about. Here’s what we found.

  • Since dealers sold the last R-134a Jeep (Patriot MK74) in 2018, and now having converted the remaining “old” minivans (Caravans built on the RT platform were supposed to be discontinued but have held on due to high fleet demand), the only remaining FCA model that has yet to be yf converted is the Abarth 124 Spider, which we don’t expect will happen anytime soon. It’s built in Japan by Mazda and finished by Abarth in Italy, so until Mazda converts (any) of its vehicles over to yf (this one’s a cousin to the MX-5 Miata), we expect it to remain R-134a for the time being.
  • The only newcomer we saw from Ford was the Transit Connect van, which is made in Europe and has been the subject of controversy for some time as many are imported as passenger cars and later converted to avoid a 25% US tariff.
  • Mitsubishi may only sell three models in the US, but one of them holds the all-time record for the lowest refrigerant charge of any newly manufactured vehicle. Mirage uses only 9.5 ounces of R-134a! Eclipse and Outlander use yf.
  • We didn’t check any of the BMW models as they switched their entire lineup for 2018. Same goes for all JLR (Jaguar Land Rover) and Minis. We also tied off other brands that have fully switched this year, including Alfa Romeo, Chrysler, Dodge, GMC, Jeep, Lincoln and VW.
  • We could only find two holdouts (without verifying Volvo and Infinity), and not surprisingly they are Mazda and Mercedes. The latter makes sense, as there was quite a controversy over the new refrigerant more than 5 years ago that included MB recalling 432 SL-Class yf vehicles through US dealers back in 2012. And now that EPA’s MY2021 cutoff has officially been revoked, there’s a real possibility that we may not see Mercedes use yf in the States for many years (if ever). As it stands now the only reason they would want (or need) to switch is if they really need the CO2 credits (which most manufacturers of large, heavy vehicles with big engines need to meet EPA targets). But Daimler is in a unique position as they build some of the most expensive, high-end luxury vehicles in country, and as such they command a premium which likely includes a few dollars to “purchase credits” from other OEMs who have extra to sell (such as those who focus on smaller, lighter, more fuel-efficient vehicles with smaller engines, hybrids and/or BEVs). Mazda on the other hand is just exactly that. 2019 Mazdas average 28.2 mpg with their lowest (CX-9) getting 23. Meanwhile MB models average only 20.9 mpg, and with both around 2% market share, you’re not dealing with huge offsets anyway.
  • Acura converted ILX, MDX and RDX production over to yf, but not all variants. MDX hybrids still use R-134a with ND-OIL11 (POE). And now that Honda uses yf in the HR-V, they have only to change Fit to complete their lineup.
  • Hyundai switched a big portion of their systems this year, too. Santa Fe, Sonata, Tucson, and Veloster now use yf, which gives Hyundai a 2/3 internal majority. And in most likelihood, two of the models we saw with R-134a (Elantra and Santa Fe XL) were probably built right before the factory switch to yf, considering that Elantra GT and Santa Fe base already use it. If that’s the case, they saved hybrid models for last to switch, and as we’ve seen with others, this too makes sense given their added complexity.

Note: If you’re a regular reader of my “Service Port” column in MACS ACtion® Magazine, you may have noticed that we didn’t include our usual chart in the April 2019 issue, and the reason is simple: It’s just too big! This year we decided to list out every make and model that we’ve been following over the years, and compile one master list that includes exactly what you’ve been asking for: what uses what. So we’re posting it here on our MACS WordPress BLOG, along with this expanded version of the print article. And while you’re here, make sure you check out the other A/C articles we’ve posted as well.

Thanks for reading!

Oh, and by the way, this article, and the contents of the chart below are (as all MACS works are…) ©2019 Mobile Air Conditioning Society Worldwide. So, PLEASE don’t copy our work and try to pass it off as your own (you know who you are). That’s called plagiarism, and you’ve been told not to do that since you were in grade school. It’s not nice to steal from others, so you shouldn’t do it, and also, it’s just plain wrong. Thanks!
