4.
TEST THE (P73) OR (P70) MIRROR MOTOR COMMON
DRIVER CIRCUIT SHORTED TO THE (C910) OR (C917)
MIRROR HEATER GROUND CIRCUIT.
Measure the resistance between the (P73) or (P70) Mirror Motor Com-
mon Driver circuit and the (C910) or (C917) Mirror Heater Ground cir-
cuit.
Is the resistance below 5000.0 ohms?
Yes
>> Repair the (P73) or (P70) Mirror Motor Common Driver
circuit for a short to the (C910) or (C917) Mirror Heater
Ground Circuit.
Perform BODY VERIFICATION TEST - VER 1.
No
>> Replace the appropriate Memory Mirror Module.
Perform BODY VERIFICATION TEST - VER 1.

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.
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.

>> 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 Com-
mon Driver circuit and ground.
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.
