- When Monitored:

Continuously.

- Set Condition:

When the Driver/Passenger Door Module senses a value below the tolerance of the mirror motor on the Mirror Horizontal Motor Driver circuit for over 10 ms, this code will set.

With the scan tool, read DTC's.

Does the scan tool display B1D22 or B1D2E-MIRROR HORIZONTAL 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 BODY VERIFICATION TEST - VER 1. Body Verification Test

2.TEST FOR A SHORTED MIRROR





Disconnect the appropriate mirror connector.

With the scan tool, erase DTC's.

Operate the Mirror Switch in all directions several times.

Cycle the ignition from on to off three times.

Turn the ignition on.
