B1D0C
B1D0C-DRIVER MIRROR VERTICAL POSITION SENSOR INPUT CIRCUIT LOW
For a complete wiring diagram, refer to the Wiring Information. Electrical Diagrams
- When Monitored:
Continuously.
- Set Condition:
When the Driver Door Module senses less than 0.16 volts on the Driver Mirror Vertical Position Signal circuit for over 100ms., this code will set.
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 three times.
5. Turn the ignition on.
6. With the scan tool, read active DTCs.
Does the scan tool display B1D0C DRIVER MIRROR VERTICAL POSITION SENSOR INPUT CIRCUIT LOW 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. (P145) DRIVER MIRROR POSITION SENSOR SUPPLY
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 ground at the mirror connector.
Is the voltage above 4.8 volts?
No
- Go To 6
Yes
- Go To 3
3. (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL
NOTE: The graphic shows the terminal end of the connector for reference only. Back probe the wire end of the connector.
1. Reconnect the mirror connector.
2. Back probe and measure the voltage between the (P67) Driver Mirror Vertical Position Signal circuit and ground at the mirror connector.
Is the voltage between 0.7 volts and 4.2 volts?
Yes
- Record the measurement and Go To 5
No
- Go To 4
4. (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL WIRE FOR A SHORT TO GROUND
1. Turn the ignition Off.
2. Disconnect the appropriate mirror connector.
3. Disconnect the Driver Door Module C4 connector.
4. Measure the resistance between the (P67) Driver Mirror Vertical Position Signal circuit and ground at the Door Module C4 connector.
Is the resistance below 5,000 Ohms?
Yes
- Repair the (P67) Driver Mirror Vertical Position Signal circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Replace the Driver Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
5. TEST THE (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL WIRE FOR AN 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 reference only. Back probe the wire end of the connector.
2. Back probe and measure the voltage between the (P67) Driver Mirror Vertical Position Signal circuit and ground.
Is the voltage the same as what was measured at the mirror in the previous step?
No
- Repair the (P67) Driver Mirror Vertical Position Signal circuit for an open from the mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
Yes
- Replace the Driver Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
6. (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 reference 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 to the mirror.
- Perform the VERIFICATION TEST. Body Verification Test.
No
- Replace the Driver Door Module.
- Perform the VERIFICATION TEST. Body Verification Test.
