B1D22-11-DRIVER MIRROR HORIZONTAL MOTOR CONTROL - CIRCUIT SHORT TO GROUND





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Continuously.

- Set Condition:
The Door Module senses a short low on the (P75) Driver Mirror Horizontal Driver circuit for more than two seconds.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With a scan tool, record and erase DTCs.
3. Turn the turn signal on, if equipped with turn signal mirror.
4. Turn the puddle lamps on, if equipped with puddle lamp mirror.
5. Turn the rear defogger on, if equipped with heated mirror.
6. Press and release the Mirror Select switch to select the Driver Outside Rearview Mirror.
7. Operate the Mirror Adjust switch in all directions several times while monitoring the scan tool for DTCs. NOTE: After adjusting the mirror in one direction wait at least two seconds before adjusting the mirror in the opposite direction, as this will allow time for an active fault to set if present.

Does the scan tool display B1D22-11-DRIVER MIRROR HORIZONTAL MOTOR CONTROL - CIRCUIT SHORT TO GROUND?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension. For vehicle's equipped with folding outside rearview mirrors, repeat test with mirror folded. If DTC is now active, Go To 2.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK (P75) DRIVER MIRROR HORIZONTAL DRIVER CIRCUIT FOR A SHORT TO GROUND




1. Turn the ignition off.
2. Disconnect the Driver Outside Rearview Mirror C2 (Component Side) harness connector from the Door Module.
3. Measure the resistance between ground and the (P75) Driver Mirror Horizontal Driver circuit.

Is the resistance below 10K Ohms?

Yes

- Repair the short to ground in the (P75) Driver Mirror Horizontal Driver circuit. If the wiring harness and harness connector are okay, replace the Driver Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No, with Heated/Turn Signal Mirror

- Go To 3

No, without Heated/Turn Signal Mirror

- Go To 4

3. CHECK (P75) DRIVER MIRROR HORIZONTAL DRIVER CIRCUIT FOR A SHORT TO (C160) DRIVER MIRROR HEATER RETURN CIRCUIT OR TO (P593) DRIVER MIRROR TURN SIGNAL RETURN CIRCUIT




1. For heated mirror, measure the resistance between the (P75) Driver Mirror Horizontal Driver circuit and the (C160) Driver Mirror Heater Return circuit at the Driver Outside Rearview Mirror C2 (Component Side) harness connector.
2. For turn signal mirror, measure the resistance between the (P75) Driver Mirror Horizontal Driver circuit and the (P593) Driver Mirror Turn Signal Return circuit at the Driver Outside Rearview Mirror C2 (Component Side) harness connector.

Is the resistance below 10K Ohms for any measurement?

Yes

- Repair all circuits with a resistance below 10K Ohms for a short to the (P75) Driver Mirror Horizontal Driver circuit. If the wiring harness and harness connector are okay, replace the Driver Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. CHECK (P75) DRIVER MIRROR HORIZONTAL DRIVER CIRCUIT FOR A SHORT TO (P69) DRIVER MIRROR SENSOR GROUND CIRCUIT




1. Disconnect the Driver Outside Rearview Mirror C1 (Component Side) harness connector from the Door Module.
2. Measure the resistance between the (P75) Driver Mirror Horizontal Driver circuit and the (P69) Driver Mirror Sensor Ground circuit at the Driver Outside Rearview Mirror C2 and C1 (Component Side) harness connectors.

Is the resistance below 10K Ohms?

Yes

- Repair the (P75) Driver Mirror Horizontal Driver circuit for a short to the (P69) Driver Mirror Sensor Ground circuit. If the wiring harness and harness connector are okay, replace the Driver Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No, with Puddle Lamp Mirror

- Go To 5

No, without Puddle Lamp Mirror

- Inspect the wiring harness and harness connector for damage and repair as necessary. If the wiring harness and harness connector are okay, replace the Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. CHECK (P75) DRIVER MIRROR HORIZONTAL DRIVER CIRCUIT FOR A SHORT TO (P591) DRIVER PUDDLE LAMP RETURN CIRCUIT




1. Measure the resistance between the (P75) Driver Mirror Horizontal Driver circuit and the (P591) Driver Puddle Lamp Return circuit at the Driver Outside Rearview Mirror C2 and C1 (Component Side) harness connectors.

Is the resistance below 10K Ohms?

Yes

- Repair the (P75) Driver Mirror Horizontal Driver circuit for a short to the (P591) Driver Puddle Lamp Return circuit. If the wiring harness and harness connector are okay, replace the Driver Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Inspect the wiring harness and harness connector for damage and repair as necessary. If the wiring harness and harness connector are okay, replace the Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
