B1D0A

B1D0A-DRIVER MIRROR POSITION SENSOR POWER SUPPLY CIRCUIT HIGH







- When Monitored:
Continuously.

- Set Condition:
When the Driver Door Module senses voltage above 5.5 volts on the Driver Mirror Position Sensor Supply circuit for over 30 ms., this code will set.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase the 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. With the scan tool, read active DTCs.

Does the scan tool display B1D0A DRIVER MIRROR POSITION SENSOR POWER SUPPLY CIRCUIT HIGH as Active?

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 MIRROR




1. Turn the ignition off.
2. Disconnect the Driver Mirror connector.
3. Turn the ignition on.
4. Measure the voltage between the (P145) Driver Mirror Position Sensor Supply circuit and the (P69) Driver Mirror Sensor Ground circuit.

Choose the result.

Between 4.8 and 5.2 volts

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

Greater than 5.2 volts

- Go To 5

Less than 4.8 volts

- Go To 3

3. TEST THE (P69) DRIVER MIRROR SENSOR GROUND WIRE FOR AN OPEN




1. Turn the ignition off.
2. Measure the resistance between the (P69) Driver Mirror Sensor Ground and the (Z912) Ground circuit in the Mirror connector.

Is the resistance below 2.0 Ohms?

No

- Check and repair the (P69) Driver Mirror Sensor Ground circuit for an open from the mirror connector to the module connector. If the wiring is all right, replace the Driver Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Go To 4

4. (P145) DRIVER MIRROR POSITION SENSOR SUPPLY WIRE OPEN




1. Gain access to the Driver Door Module C4 connector but DO NOT disconnect.

NOTE: The graphic shows the terminal end of the connector for referance only. Back probe the wire end of the connector.

2. Back probe and measure the voltage between the (P145) Driver Mirror Position Sensor Supply circuit and ground.

Is the voltage above 4.8 volts?

Yes

- Repair the (P145) Driver Mirror Position Sensor Supply circuit for an open circuit to the mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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

5. TEST THE (P145) DRIVER MIRROR POSITION SENSOR SUPPLY WIRE SHORTED TO VOLTAGE




1. Turn the ignition off.
2. Disconnect the Driver Door Module C4 harness connector.
3. Turn the ignition on.
4. Measure the voltage between ground and the (P145) Driver Mirror Position Sensor Supply circuit.

Is there any voltage present?

Yes

- Repair the (P145) Driver Mirror Position 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.
