Why should you come to MACS 2015 Training Event and Trade Show, February 5-7, 2015 at the Caribe Royale All Suite Hotel and Convention Center? Well, there are about 12 billion reasons! Did you know that the vehicle climate and thermal management portion of the automotive aftermarket is worth $12 billion dollars in parts and repair work annually?
This week we will look at the training being offered at MACS 2015 Training Event and we’ll begin today with the passenger and light truck classes.
Diagnosing and repairing the top auto HVAC problems
The automotive HVAC system continues to undergo changes driven by regulatory pressure to increase fuel economy and reduce emissions. Participants will get important information on new components such as A/C line heat exchangers, oil traps in compressors, electronic displacement control and thermal storage material equipped evaporators used in idle stop vehicles. Ryan Kooiman of Four Seasons will cover updated diagnostic and service techniques required by new components and reduced refrigerant and oil capacity. He’ll also discuss hybrid vehicle system service and compressor replacement, pattern failures and fixes, along with dual A/C system diagnosis and service techniques. The goal of this class is to prepare the technician with the skills needed to properly diagnose these systems, verify proper system operation, improve post repair HVAC system performance, and reduce come backs. (Scheduled Thursday morning and Thursday afternoon.)
Diagnostics under the dash
Control head flashing and A/C electronic control diagnostics will be part of this seminar conducted by Delphi’s Dave Hobbs. The training will help technicians polish their skills on challenges including battery drains, blower diagnostics and cabin odors using the latest tips and tricks. He’ll also explore some case studies and demonstrate how to put some interesting tools to good use. (Scheduled Thursday morning and Saturday afternoon.)
Diagnosing vehicle networks and data lines
When a MIL is lit, a scanner is normally the first choice to find DTC’s and data stream. But when the scanner does not communicate or if series network codes are set, it can often leave a technician with no direction. This clinic with Dave Scaler of MEA is designed to help the technician attack a “NO COMMUNICATION” problem with confidence, by learning and understanding how onboard computers are tied together with multiplex networks. It includes CCD, PCI, Class 2, SCP, CAN, UART and more. (Scheduled once on Thursday morning.)
Diagnosing externally controlled compressors
This special, three-part training session will be presented both “in the classroom” and “out in the shop.” Sponsored by Behr Hella Service, Peter Bradley will cover modern system diagnostics with externally controlled compressors, including integrated A/C and cooling systems. Class will then extend outdoors beneath the Porte-Cochère, where climate control diagnostics will be demonstrated on a live vehicle. (Scheduled Thursday morning and Saturday morning.)
HVAC technology and service insights
Jerry Mungle of ACDelco will cover recent advances in automotive HVAC in this session. Topics include new refrigerants (R-1234yf and others), hybrid and electric vehicle thermal management, refrigerant circuit enhancements, new actuators, networking, sensors, reprogramming, service procedures, tools and equipment. (Scheduled Thursday afternoon and Saturday morning.)
In this clinic, John Thornton of Autotrain will explain what J2534 pass through is, how it works and what it can and cannot do. He will discuss the tools needed and the problems that can be fixed with these tools, how to use OEM websites to find reflash information, the profits that can be made with a J2534 tool and where to find the tools. This class includes demonstrations on GM and Ford systems. (Scheduled Thursday afternoon and Saturday morning.)
Variable displacement compressor theory, trouble diagnostics and case studies
One of the newest and most complicated additions to the mobile A/C world is the electronically controlled, variable displacement compressor. This class with Brett Grover and Wally Mouradian of DENSO will discuss theory of the system, including troubleshooting and diagnosis specific to the variable displacement compressor. Case studies will also be reviewed. (Scheduled Thursday afternoon and Saturday afternoon.)
Diagnosing and understanding system airflow issues and auxiliary cooling options
You can’t “see” airflow and it’s hard to measure accurately. In this clinic Peter McArdle of Four Seasons will explain how to get a “solid” handle on airflow diagnostics. Poor A/C performance and excessive high side pressures are often caused by inadequate airflow, yet the engine may show NO signs of overheating. How can this be? Peter will discuss common airflow related pattern failures and fixes, cold startup fan noise, electric fan operating strategies, and new cooling fan technology, including understanding conventional and electronic viscous (EV) fan clutch operation and how to test them. He will also explain how adding an auxiliary cooling fan or fluid cooler may be an effective solution to a vexing cooling problem. (Scheduled once on Saturday morning.)
Tomorrow’s blog will discuss the heavy duty and off road vehicle classes.
