Course Description
heating, air management and control subsystem concern diagnosis, service and repair
Test-Out Procedures
Technicians who have taken the prerequisites for the classroom course and have extensive experience
in the subject may elect to test out of the course
• The test-out will consist of the same written and hands-on evaluations used in the classroom course
• The instructor will serve only as an evaluator, and will not provide assistance or coaching beyond giving instructions for completing the tests
• Technicians will have 1 opportunity to pass the test out
In order to satisfactorily complete a test-out of this course, the technician must demonstrate mastery of
Written Test
A score of 80% or higher is required to pass the written test
Hands-On Evaluation
The technician must correctly complete all of the hands-on evaluations
Course Objectives
Any or all of the following objectives may be included in the Test-Out They can be used to determine
if a technician should attempt to test out of the course
• Retrieve DTCs from the control head and Powertrain Control Module
• Diagnose refrigeration, heating, air management and control subsystem concerns
• Diagnose powertrain control concerns related to the compressor clutch and electric engine cooling fan circuit(s)
• Use special service tools and diagnostic and service equipment related to the refrigeration, heating and control subsystems
• Perform service procedures related to the refrigeration, heating, air management and control subsystems
• Locate A/C system components on a vehicle with a TXV valve
• Locate A/C system components on a vehicle with an evaporator temperature sensor
