B1D2E-11-PASSENGER MIRROR HORIZONTAL MOTOR CONTROL - CIRCUIT SHORT TO GROUND







- When Monitored:
Continuously.

- Set Condition:
The Door Module senses a short low on the (P74) Passenger Mirror Horizontal Driver circuit for more than two seconds.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. Using a scan tool, record and erase Diagnostic Trouble Codes (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 Passenger 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.

Is the DTC active?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. For vehicle's equipped with folding outside rearview mirrors, repeat test with mirror folded. If DTC is now active, Go To 2. Otherwise, use the wiring diagram/schematic as a guide and inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK (P74) PASSENGER MIRROR HORIZONTAL DRIVER CIRCUIT FOR A SHORT TO GROUND




1. Turn the ignition off.
2. Disconnect the Passenger Outside Rearview Mirror C2 (Component Side) connector from the Door Module C2 connector.
3. Measure the resistance of the (P74) Passenger Mirror Horizontal Driver circuit between ground and the Passenger Outside Rearview Mirror C2 (Component Side) connector.

Is the resistance below 10K Ohms?

Yes

- Repair the (P74) Passenger Mirror Horizontal Driver circuit for a short to ground. If the wiring harness and connector are okay, replace the Passenger 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 (P74) PASSENGER MIRROR HORIZONTAL DRIVER CIRCUIT FOR A SHORT TO (C170) PASSENGER MIRROR HEATER RETURN CIRCUIT OR TO (P595) PASSENGER MIRROR TURN SIGNAL RETURN CIRCUIT




1. For heated mirror, measure the resistance between the (P74) Passenger Mirror Horizontal Driver circuit and the (C170) Passenger Mirror Heater Return circuit at the Passenger Outside Rearview Mirror C2 (Component Side) connector.
2. For turn signal mirror, measure the resistance between the (P74) Passenger Mirror Horizontal Driver circuit and the (P595) Passenger Mirror Turn Signal Return circuit at the Passenger Outside Rearview Mirror C2 (Component Side) connector.

Is the resistance below 10K Ohms for either measurement?

Yes

- Repair all circuits with a resistance below 10K Ohms for a short to the (P74) Passenger Mirror Horizontal Driver circuit. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. CHECK (P74) PASSENGER MIRROR HORIZONTAL DRIVER CIRCUIT FOR A SHORT TO (P66) PASSENGER MIRROR SENSOR GROUND CIRCUIT




1. Disconnect the Passenger Outside Rearview Mirror C1 (Component Side) connector from the Door Module C1 connector.
2. Measure the resistance between the (P74) Passenger Mirror Horizontal Driver circuit and the (P66) Passenger Mirror Sensor Ground circuit at the Passenger Outside Rearview Mirror C2 and C1 (Component Side) connectors.

Is the resistance below 10K Ohms?

Yes

- Repair the (P74) Passenger Mirror Horizontal Driver circuit for a short to the (P66) Passenger Mirror Sensor Ground circuit. If the wiring harness and connector are okay, replace the Passenger 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 and connectors for damage and repair as necessary. If the wiring and connectors are okay, replace the Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. CHECK (P74) PASSENGER MIRROR HORIZONTAL DRIVER CIRCUIT FOR A SHORT TO (P592) PASSENGER PUDDLE LAMP RETURN CIRCUIT




1. Measure the resistance between the (P74) Passenger Mirror Horizontal Driver circuit and the (P592) Passenger Puddle Lamp Return circuit at the Passenger Outside Rearview Mirror C2 and C1 (Component Side) connectors.

Is the resistance below 10K Ohms?

Yes

- Repair the (P74) Passenger Mirror Horizontal Driver circuit for a short to the (P592) Passenger Puddle Lamp Return circuit. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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