9302-MODE DOOR CONTROL CIRCUIT PERFORMANCE





For a complete wiring diagram Refer to the Wiring Information Electrical Diagrams.

- When Monitored:
With the Ignition Switch in the on position and the A/C Heater Control is awake.

- Set Condition:
This code will set when the Mode Door Control circuit is open or shorted to voltage.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase all HVAC DTC's.
3. Operate the HVAC system.
4. Wait 30 seconds.
5. With the scan tool, read all HVAC DTC's.

Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

2. MODE DOOR CONTROL CIRCUIT SHORTED TO VOLTAGE
1. Turn the ignition off.
2. Disconnect the A/C Heater Control harness connectors.
3. Disconnect the Mode Door Actuator harness connector.
4. Turn the ignition on.
5. Measure the voltage of the Mode Door Control circuit.

Is there any voltage present?

Yes

- Repair the Mode Door Control circuit for a short to voltage.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Go to 3

3. MODE DOOR CONTROL CIRCUIT OPEN
1. Turn the ignition off.
2. Measure the resistance of the Mode Door Control circuit.

- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Go To 4

4. MODE DOOR GROUND CIRCUIT SHORTED TO VOLTAGE
1. Turn the ignition on.
2. Measure the voltage of the Mode Door Ground Circuit.

Is there any voltage present?

Yes

- Repair the (Z910) Ground circuit for a short to voltage.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Go to 5

5. MODE DOOR GROUND CIRCUIT OPEN
1. Turn the ignition off.
2. Measure the resistance of the Mode Door Ground circuit.

Does the ohm meter read open circuit?

Yes

- Repair the Mode Door Ground circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Replace the A/C Heater Control.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test
