WHEN MONITORED
Continuously
SET CONDITION
When the Memory Mirror Module senses voltage present on the Mirror Motor Common Control circuit, when there should not be, for over 10 ms, this code will set.
NOTE: This test covers both the Driver and Passenger code depending on the side the code appeared in.
POSSIBLE CAUSES
- (P73) or (P70) mirror motor common driver circuit short to voltage
- Mirror shorted

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 B1D1C or B1D28-MIRROR MOTOR COMMON CONTROL CIRCUIT HIGH?
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 AN OPEN MIRROR
Turn the ignition off.
Disconnect the appropriate mirror connector.
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 B1D1C or B1D28-MIRROR MOTOR COMMON CONTROL CIRCUIT HIGH?
NO: Replace the Mirror. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
YES: Go to 3
3. TEST THE (P73) OR (P70) MIRROR MOTOR COMMON DRIVER WIRE FOR A SHORT TO VOLTAGE
Measure the voltage between the (P73) or (P70) Mirror Motor Common Driver circuit and ground.
Q: Is the voltage above 0.5 volts?
YES: Repair the (P73) or (P70) Mirror Motor Common Driver circuit for a short to voltage. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace the appropriate Memory Mirror Module. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
