B1D0A

B1D0A-DRIVER MIRROR POSITION SENSOR POWER SUPPLY CIRCUIT HIGH





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

- When Monitored:
Continuously.

- Set Condition:
If the Driver Door Module senses voltage is greater than 5.5 volts for more than 30 ms on the (P669) Driver Mirror Sensor Supply circuit.





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

Does the scan tool display: B1D0A-DRIVER MIRROR POSITION SENSOR POWER SUPPLY 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 the 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. Turn the ignition on.
4. Measure the voltage between the (P669) Driver Mirror Sensor Supply circuit and the (P69) Driver Mirror Sensor Ground circuit.

What is the voltage?

4.8 to 5.2 volts

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

Below 4.8 volts

- Go To 3

Above 5.2 volts

- Go To 5

3. CHECK THE (P669) DRIVER MIRROR SENSOR SUPPLY CIRCUIT FOR AN OPEN




1. Turn the ignition off.
2. Disconnect the Driver Door Module C2 connector.
3. Measure the resistance of the (P669) Driver Mirror Sensor Supply 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 4

No

- Repair the (P669) Driver Mirror Sensor Supply circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. 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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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

5. CHECK THE (P669) DRIVER MIRROR SENSOR SUPPLY 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 (P669) Driver Mirror Sensor Supply circuit.

Is the voltage above 0.2 volt?

Yes

- Repair the (P669) Driver Mirror Sensor Supply circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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