16 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.
Disconnect the Body Control Module C2 harness connector.
Measure the resistance of the Mode Door Feedback Signal circuit between the BCM
C2 connector and the Inline connector (cavity #11).
Is the resistance below 5.0 ohms?
Yes → Go To 17
→ Repair the Mode Door Feedback Signal circuit for an open.
No
17 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.
Disconnect the Body Control Module C2 harness connector.
Disconnect the Body Control Module C1 harness connector.
Measure the resistance between the Sensor Ground circuit in the BCM C1 connector
and the Mode Door Feedback Signal circuit in the BCM C2 connector.
Is the resistance below 1000.0 ohms?
Yes → Repair the Mode Door Feedback Signal circuit for a short to the
→ Go To 18
No
18 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.
Reconnect the Body Control Module C1 & C2 harness connectors.
Turn the ignition on.
With the DRBIII , read the Mode Door voltage.
Connect a jumper wire between the Mode Door Feedback Signal circuit (cavity #11)
and the 5 volt supply circuit (cavity #6) at the in-line connector C202/3 (I/P harness
side).
Does the DRBIII display voltage at approximately 5.0 volts?
Yes → Ensure the wiring to the actuator is okay. If the wiring is okay,
→ Replace the Body Control Module.
No
