The numbers below refer to the step numbers on the diagnostic table.
9. Tests for the proper operation of the circuit in the high voltage range. If the fuse in the jumper opens when you perform this test, the signal circuit is shorted to ground.
19. The inside air temperature sensor is an integrated into the heater and A/C control.
20. Tests to ensure that the heater and A/C control has the ability to command the LH temperature valve actuator.
22. Tests for the proper operation of the circuit in the high voltage range when the actuator is at rest.
23. Tests for the proper operation of the circuit in the high voltage range when the actuator is at rest.
24. Ensures the heater and A/C control has the ability to control the LH temperature valve actuator.
25. Ensures the heater and A/C control has the ability to control the LH temperature valve actuator.
26. Ensures the heater and A/C control has the ability to control the LH temperature valve actuator. Test lamp will be illuminated when connection made. Test lamp should increase intensity when commanded.
27. Ensures the heater and A/C control has the ability to control the LH temperature valve actuator. Test lamp will be illuminated when connection made. Test lamp should increase intensity when commanded.
32. Tests to ensure that the heater and A/C control has the ability to command the RH temperature valve actuator.
34. Tests for the proper operation of the circuit in the high voltage range when the actuator is at rest.
35. Tests for the proper operation of the circuit in the high voltage range when the actuator is at rest.
36. Ensures the heater and A/C control has the ability to control the RH temperature valve actuator.
37. Ensures the heater and A/C control has the ability to control the RH temperature valve actuator.
38. Ensures the heater and A/C control has the ability to control the RH temperature valve actuator. Test lamp will be illuminated when connection made. Test lamp should increase intensity when commanded.
39. Ensures the heater and A/C control has the ability to control the RH temperature valve actuator. Test lamp will be illuminated when connection made. Test lamp should increase intensity when commanded.
