B1D10

B1D10-DRIVER MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT HIGH





For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

- When Monitored:
Continuously.

- Set Condition:
The (P65) Driver Mirror Horizontal Position Signal circuit supplies input to the Driver Door Module (DDM). Diagnostic Trouble Code (DTC) B1D10 will set if the input value is greater than the known good (stored) value for more than 60 ms.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. Using a scan tool, record and erase DTCs.
3. Operate the Mirror Switch in all directions several times.
4. Cycle the ignition from on to off three times.
5. Turn the ignition on.
6. Using a scan tool, read DTCs.

Does the scan tool display DTC B1D10-DRIVER MIRROR HORIZONTAL POSITION SENSOR INPUT 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. Body Verification Test.

2. TEST FOR A SHORTED OUTSIDE REARVIEW MIRROR




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

What is the voltage?

4.8 to 5.2 Volts

- Replace the Driver Outside Rearview Mirror.
- Perform BODY VERIFICATION TEST. Body Verification Test.

Above 5.2 Volts

- Go To 3

Below 4.8 Volts

- Go To 4

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




1. Turn the ignition off.
2. Disconnect the Driver Door Module C2 connector.
3. Turn the ignition on.
4. Measure the Voltage of the (P65) Driver Mirror Horizontal Position Signal circuit between the Driver Door Module C2 connector and ground.

Is the voltage above 0.2 of a volt?

Yes

- Repair the (P65) Driver Mirror Horizontal Position Signal circuit for a short to Voltage.
- Perform BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Driver Door Module (DDM).
- Perform BODY VERIFICATION TEST. Body Verification Test.

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




1. Turn the ignition off.
2. Disconnect the Driver Door Module C2 connector.
3. 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.

Is the resistance below 2.0 Ohms?

Yes

- Go To 5

No

- Repair the (P65) Driver Mirror Horizontal Position Signal circuit for an open.
- Perform BODY VERIFICATION TEST. Body Verification Test.

5. CHECK THE (P69) DRIVER MIRROR SENSOR GROUND CIRCUIT FOR AN OPEN




1. Measure the resistance of the (P69) Driver Mirror Sensor Ground circuit between the Driver Outside Rearview Mirror connector and the Driver Door Module C2 connector.

Is the resistance below 2.0 Ohms?

Yes

- Replace the Driver Door Module (DDM).
- Perform BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the (P69) Driver Mirror Sensor Ground circuit for an open.
- Perform BODY VERIFICATION TEST. Body Verification Test.
