8 Turn the ignition off.
Disconnect the C202 (manual A/C) or C203 (ATC) in-line connector (HVAC) located in
the center of the instrument panel above the accelerator pedal.
Turn off all lights and close the driver door latch so the courtesy lamps will go off.
Measure the resistance between ground and the sensor ground circuit (cavity #5) in
the inline connector (I/P harness side).
Is the resistance below 5.0 ohms?
Yes → Go To 9
→ Go To 14
No
9 Disconnect the C202 (manual A/C) or C203 (ATC) in-line connector (HVAC) located in
the center of the instrument panel above the accelerator pedal.
Disconnect the Body Control Module C1 harness connector
Measure the resistance of the Common Door Driver circuit between the BCM C1
connector and the HVAC in line connector (cavity 1).
Is the resistance below 5.0 ohms?
Yes → Go To 10
→ Repair the Common Door Driver circuit for an open.
No
10 Disconnect the C202 (manual A/C) or C203 (ATC) in-line connector (HVAC) located in
the center of the instrument panel above the accelerator pedal.
Disconnect the Body Control Module C1 harness connector
Measure the resistance of the Mode Door Driver circuit between the BCM C1
connector and the HVAC in line connector (cavity 2).
Is the resistance below 5.0 ohms?
Yes → Go To 11
→ Repair the Mode Door Driver circuit for an open.
No
11 Turn the ignition off.
Ensure the C202/3 inline connector is connected at this time.
With the DRBIII , erase DTC's.
Disconnect the BCM C1 harness connector.
Backprobe one voltmeter lead to the Common Door Driver ckt in the BCM C1
connector and the other to chassis ground.
Reconnect the BCM C1 harness connector.
Turn the ignition on.
Push (move) the mode control as follows: Recirc switch Off: Panel Switch On: then
Recirc Switch ON while observing the voltmeter.
Did the voltage ever go above 10.0 volts?
Yes → Go To 12
→ Replace the Body Control Module (common door driver open).
No
