For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

Continuously.

- Set Condition:

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

Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION

Turn the ignition on.

With the scan tool, record and 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.

With the scan tool, read DTC's.

Does the scan tool display B1D1F or B1D2B-MIRROR VERTICAL MOTOR CONTROL CIRCUIT LOW?

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 THE (P71) OR (P72) MIRROR VERTICAL MOTOR DRIVER WIRE FOR A SHORT TO GROUND





Turn the ignition off.

Disconnect the appropriate Door Module C2 connector.

Measure the resistance between ground and the (P71) or (P72) Mirror Vertical Motor Driver circuit.

Is the resistance below 5000.0 ohms?

Yes

- Repair the (P71) or (P72) Mirror Vertical Motor Driver circuit for a short to ground or replace the mirror.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go to 3

3. TEST THE (P71) OR (P72) MIRROR VERTICAL MOTOR DRIVER CIRCUIT SHORTED TO THE (C160) OR (C170) MIRROR HEATER GROUND CIRCUIT.





Measure the resistance between the (P71) or (P72) Mirror Vertical Motor Driver circuit and the (C160) or (C170) Mirror Heater Ground circuit.

Is the resistance below 5000.0 ohms?

Yes

- Repair the (P71) or (P72) Mirror Vertical Motor Driver circuit for a short to the (C160) or (C170) Mirror Heater Ground Circuit or replace the mirror.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Replace the appropriate Door Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
