Objectives 752 Air Conditioning and Climate Control 15. Identify key places to look for leakage in the A/C System. 16. Perform a refrigerant recovery/recycling/evacuation and recharge of an A/C System including leak detection using an electronic refrigerant leak detector. 17. Identify the function and location of components used for A/C System Control including the temperature control system, air inlet control and blend door operation, servo motor operation, blower speed control, airflow mode control, air mix temperature control, and air distribution control. 18. Demonstrate the ability to read and interpret Mode Position Diagrams and Damper Operation Charts. 19.
Develop a strategy to diagnose Computer Controlled A/C Systems based upon identifying inputs and outputs to the system and determining how they affect ECU operation. 20. Develop a diagnostic strategy for an A/C System with a 3-wire (variable voltage) pressure sensor by creating a number of A/C system faults (including a condenser airflow restriction and an number of 3-wire pressure sensor shorts) while monitoring the results using a pressure gauge set, a DVOM, and Techstream. 21. Perform self-diagnosis using Repair Manual Check Mode Procedure. 22. Retrieve A/C Diagnostic Trouble Codes (DTC). 23. Use Techstream DATA LIST to monitor A/C component operation. 24.
Perform ACTIVE TEST using Techstream to assure proper component operation. 25. Use Techstream to customize various A/C System functions. b Technical Training
