B1D11-11-PASSENGER MIRROR POSITION SENSOR POWER SUPPLY - CIRCUIT SHORT TO GROUND





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

Theory of Operation

The mirror position sensor is used in conjunction with the memory system. Anytime the mirror changes position, the sensor changes its value. That value is stored in the door module. When a command from the memory set switch is received, the module will position the mirror to the exact position chosen by the particular driver.

- When Monitored:
Continuously.

- Set Condition:
The Door Module senses a short low on the (A857) 5-volt Supply circuit for more than two seconds with the output turned on.





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 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.

Does the scan tool display: B1D11-11-PASSENGER MIRROR POSITION SENSOR POWER SUPPLY - CIRCUIT SHORT TO GROUND as 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, using the wiring diagrams as a guide, check all related connectors for signs of water intrusion, corrosion, pushed out or bent terminals and poor pin fit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK (A857) 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO GROUND




1. Turn the ignition off.
2. Disconnect the Passenger Outside Rearview Mirror C1 (Component Side) connector from the Door Module C1 connector.
3. Measure the resistance between ground and the (A857) 5-volt Supply circuit in the Passenger Outside Rearview Mirror C1 (Component Side) connector.

Is the resistance below 10K Ohms?

Yes

- Repair the (A857) 5-volt Supply circuit for a short to ground. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. CHECK (A857) 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO ANY MIRROR SENSOR GROUND OR RETURN CIRCUIT




1. Disconnect the Passenger Outside Rearview Mirror C2 (Component Side) connector from the Door Module C2 connector.
2. Measure the residence between the (A857) 5-volt Supply circuit (C1-10) and all Mirror Sensor Ground and Return circuits.

Is the resistance below 1.2K Ohms on any measurements?

Yes

- Repair the (A857) 5-volt Supply circuit for a short to a Mirror Sensor Ground or Return circuit. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. CHECK (A857) 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO ANY PASSENGER MIRROR DRIVER CIRCUIT




1. Measure the resistance between the (A857) 5-volt Supply circuit (C1-10) and all Passenger Mirror Driver circuits in the Passenger Outside Rearview Mirror C1 and C2 (Component Side) connectors.

Is the resistance below 10K Ohms for any measurement?

Yes

- Repair all circuits with a resistance below 10K Ohms for a short to the (A857) 5-volt Supply circuit. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- 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. Door Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
