B1D0B-11-DRIVER MIRROR VERTICAL POSITION SENSOR INPUT - 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 (P67) Driver Mirror Vertical Position Signal 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 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: B1D0B-11-DRIVER MIRROR VERTICAL POSITION SENSOR INPUT - 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 the DTC is now active, Go To 2. Otherwise, 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 poor pin fit. Repair as necessary.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR A SHORT TO GROUND




1. Turn the ignition off.
2. Disconnect the Driver Outside Rearview Mirror C1 (Component Side) connector from the Door Module C1 connector.
3. Measure the resistance between Ground and the (P67) Driver Mirror Vertical Position Signal circuit in the Driver Outside Rearview Mirror C1 connector.

Is the resistance below 10K Ohms?

Yes

- Repair the (P67) Driver Mirror Vertical Position Signal circuit for a short to ground. If the wiring harness and connector are okay, replace the Driver Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. CHECK (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR A SHORT TO ANY GROUND OR RETURN CIRCUIT




1. Disconnect the Driver Outside Rearview Mirror C2 (Component Side) harness connector.
2. Measure the resistance between the (P67) Driver Mirror Vertical Positional Signal circuit (C1-7) and all Ground and Return circuits in the Driver Outside Rearview Mirror C1 and C2 (Component Side) connectors.

Is the resistance below 1.2K Ohms between the (P67) Driver Mirror Vertical Positional Signal circuit and any Ground or Return circuit?

Yes

- Repair the (P67) Driver Mirror Vertical Positional Signal circuit for a short to the Ground or Return circuit. If the wiring harness and connector are okay, replace the Driver 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.
