Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION

Turn the ignition on.
With the scan tool, record and erase DTCs.
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 DTCs.

Does the scan tool display: B1D10 or B1D19 MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT HIGH?

Yes

Go To 2

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. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

2. TEST FOR A SHORTED OUTSIDE REARVIEW MIRROR

For the Driver Memory Mirror System, proceed as follows:

Turn the ignition off.
Disconnect the Driver Outside Rearview Mirror connector.
Connect a voltmeter between the (P65) Driver Mirror Horizontal Position Signal circuit and the (P69) Driver Mirror Sensor Ground circuit.
Turn the ignition on.
Move the mirror switch to any switch position while monitoring the voltmeter.

For the Passenger Memory Mirror System, proceed as follows:

Turn the ignition off.
Disconnect the Passenger Outside Rearview Mirror connector.
Connect a voltmeter between the (P68) Passenger Mirror Horizontal Position Signal circuit and the (P66) Passenger Mirror Sensor Ground circuit
Turn the ignition on.
Move the mirror switch to any switch position while monitoring the voltmeter.

What is the voltage?

4.8 to 5.2 Volts

Replace the Outside Rearview Mirror in accordance with the Service Information.

Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

Above 5.2 Volts

Go To 3

Below 4.8 Volts

Go To 4

3. CHECK THE (P65) DRIVER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT OR THE (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE

For the Driver Memory Mirror System, proceed as follows:

Turn the ignition off.

Turn the ignition on.
Measure the voltage of the (P65) Driver Mirror Horizontal Position Signal circuit.

For the Passenger Memory Mirror System, proceed as follows:

Turn the ignition off.
Disconnect the Passenger Door Module connector.
Turn the ignition on.
Measure the voltage of the (P68) Passenger Mirror Horizontal Position Signal circuit.

Is the voltage above 0.2 volts?

Yes, Driver Mirror

Repair the (P65) Driver Mirror Horizontal Position Signal circuit for a short to voltage.

Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

Yes, Passenger Mirror

Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

No, Driver Mirror

Replace the Driver Door Module in accordance with the Service Information.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

No, Passenger Mirror

Replace the Passenger Door Module in accordance with the Service Information.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

4. CHECK THE (P65) DRIVER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT OR THE (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR AN OPEN

For the Driver Memory Mirror System, proceed as follows:

Turn the ignition off.
Disconnect the Driver Door Module C2 connector.
Measure the resistance of the (P65) Driver Mirror Horizontal Position Signal circuit between the Driver Outside Rearview Mirror connector and the Driver Door Module C2 connector.

For the Passenger Memory Mirror System, proceed as follows:

Turn the ignition off.
Disconnect the Passenger Door Module connector.
Measure the resistance of the (P68) Passenger Mirror Horizontal Position Signal circuit between the Passenger Outside Rearview Mirror connector and the Passenger Door Module C2 connector.

Is the resistance below 2.0 ohms?

Yes

Go To 5

No, Driver Mirror
