B1D0B-12-DRIVER MIRROR VERTICAL POSITION SENSOR INPUT - CIRCUIT SHORT TO BATTERY





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

- When Monitored:
Continuously.

- Set Condition:
The Door Module senses more than 400 mA current on the (A856) 5-volt Supply circuit or an open or a short high 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.

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.
