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

- When Monitored:
Continuously.

- Set Condition:
When the Passenger Door Module senses a value below the tolerance of the mirror motor on the Passenger Mirror Vertical Driver circuit for over 10 ms., this code will set.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase the DTCs.
3. Operate the Passenger Mirror Switch in all directions several times.
4. Cycle the ignition from on to off three times.
5. Turn the ignition on.
6. With the scan tool, read the DTCs.

Does the scan tool display B1D2A PASSENGER MIRROR VERTICAL MOTOR CONTROL CIRCUIT/PERFORMANCE?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. TEST FOR A SHORTED PASSENGER MIRROR




1. Disconnect the Passenger Mirror connector.
2. With the scan tool, erase the DTCs.
3. Operate the Passenger Mirror Switch in all directions several times.
4. Cycle the ignition from on to off three times.
5. Turn the ignition on.
6. With the scan tool, read the DTCs.

Does the scan tool display B1D2A PASSENGER MIRROR VERTICAL MOTOR CONTROL CIRCUIT/PERFORMANCE?

No
