Steps 5-12:
Steps 13-21:
Steps 22-30:
The numbers below refer to the step numbers on the diagnostic table.
2. This step ensures that the primary HVAC system is functioning properly.
5. If the condition does not occur when an A/C request has been made then you must bypass the A/C performance test procedures.
6. Performing the Air Conditioning System Performance Test ensures that the A/C system is operating properly for further testing.
7. This step ensures that the rear auxiliary HVAC control module is able to move the auxiliary air temperature actuator.
8. This step ensures that the front auxiliary HVAC control assembly is able to move the auxiliary air temperature actuator.
12. The circuit that is to be tested runs between the rear auxiliary HVAC control assembly and the auxiliary HVAC control processor. The circuit is the position signal from the rear auxiliary HVAC control assembly for the auxiliary air temperature actuator. The circuit only provides a reference when the front auxiliary HVAC control assembly is in the REAR CNTL position.
15. The circuit that is to be tested runs between the front auxiliary HVAC control assembly and the auxiliary HVAC control processor. The circuit is the position signal from the rear auxiliary HVAC control assembly for the auxiliary air temperature actuator. The circuit only provides a reference when the front auxiliary HVAC control assembly is in any other position than REAR CNTL position.
20. This step checks the output of the auxiliary HVAC control processor to the auxiliary air temperature actuator.
