- Driver door module

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 3 times.
Turn the ignition on.
With the scan tool, read DTC's.

Q: Does the scan tool display B1D22-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 3 times.
Turn the ignition on.
With the scan tool, read DTC's.

Q: Does the scan tool display B1D22-MIRROR HORIZONTAL MOTOR CONTROL CIRCUIT/PERFORMANCE?

NO: Replace the Mirror.
Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

YES: Go to 3

3. TEST THE (P75) OR (P74) MIRROR HORIZONTAL MOTOR DRIVER WIRE FOR A SHORT TO GROUND






Turn the ignition off.
Disconnect the appropriate Door Module C4 connector.
Measure the resistance between ground and the (P75) Mirror Horizontal Motor Driver circuit.

Q: Is the resistance below 5000.0 ohms?

YES: Repair the (P75) Mirror Horizontal Motor Driver circuit for a short to ground.
Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

NO: Go to 4

4. TEST THE (P75) MIRROR HORIZONTAL MOTOR DRIVER CIRCUIT SHORTED TO THE (Z912) OR (Z911) GROUND CIRCUIT.






Measure the resistance between the (P75) Mirror Horizontal Driver circuit and the (Z912) or (Z911) Ground circuit.

Q: Is the resistance below 5000.0 ohms?

YES: Repair the (P75) Mirror Horizontal Motor Driver circuit for a short to the (Z912) or (Z911) Mirror Heater Ground Circuit.
