7B-55 Air Conditioning System: 3 Wire harness check ignition switch turned OFF. 2) Check for proper connection to HVAC control module connector at “G52-31” and “G52-32” terminals. 3) If OK, measure resistance between “ORN” wire terminal of air intake control actuator connector and “G52-31” Is resistance below 5 Ω ? Go to Step 4. “ORN” wire open or high 4 Wire harness check intake control actuator connector and vehicle body Is resistance infinity? Go to Step 5. “ORN” wire shorted to 5 Wire harness check intake control actuator connector and vehicle body Is voltage 0 V? Go to Step 6. “ORN” wire shorted to 6 Wire harness check switch turned OFF. 2) Measure voltage between “GRN” wire terminal of air intake control actuator connector and vehicle body Is voltage 10 – 14 V? Go to Step 10. Go to Step 7. 7 Wire harness check ignition switch turned OFF. 2) Check for proper connection to HVAC control module connector at “G52-31” and “G52-32” terminals. 3) If OK, measure resistance between “GRN” wire terminal of air intake control actuator connector and “G52-32” Is resistance below 5 Ω ? Go to Step 8. “GRN” wire open or high 8 Wire harness check intake control actuator connector and vehicle body Is resistance infinity? Go to Step 9. “GRN” wire shorted to 9 Wire harness check intake control actuator connector and vehicle body Is voltage 0 V? Go to Step 10. “GRN” wire shorted to Step Action Yes No |
