B1D18

B1D18-PASSENGER MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT LOW







- When Monitored:
Continuously.

- Set Condition:
When the Passenger Door Module senses less than 0.16 of a volt on the Passenger Mirror Horizontal 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 the DTCs.
3. Operate the Passenger 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 the active DTCs.

Does the scan tool display B1D18 PASSENGER MIRROR HORIZONTAL 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. (P146) PASSENGER MIRROR POSITION SENSOR SUPPLY




1. Turn the ignition Off.
2. Disconnect the Passenger Mirror connector.
3. Turn the ignition On.
4. Measure the voltage between the (P146) Passenger Mirror Position Sensor Supply circuit and ground.

Is the voltage above 4.8 volts?

No

- Go To 6

Yes

- Go To 3

3. (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL




1. Reconnect the Passenger Mirror connector.

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 (P68) Passenger Mirror Horizontal Position Signal circuit and ground.

Is the voltage between 0.7 and 4.2 volts?

Yes

- Record the measurement and Go To 5

No

- Go To 4

4. (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL WIRE FOR A SHORT TO GROUND




1. Turn the ignition Off.
2. Disconnect the Passenger Mirror connector.
3. Disconnect the Passenger Door Module C4 connector.
4. Measure the resistance between the (P68) Passenger Mirror Horizontal Position Signal circuit and ground.

Is the resistance below 10,000 Ohms?

Yes

- Repair the (P68) Passenger Mirror Horizontal Position Signal circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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

5. TEST THE (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL WIRE FOR AN OPEN




1. Gain access to the Passenger 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 (P68) Passenger Mirror Horizontal Position Signal circuit and ground.

Is the voltage the same as was measured at the mirror in the previous step?

No

- Repair the (P68) Passenger Mirror Horizontal Position Signal circuit for an open from the mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

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

6. (P146) PASSENGER MIRROR POSITION SENSOR SUPPLY WIRE OPEN




1. Gain access to the Passenger 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 (P146) Passenger Mirror Position Sensor Supply circuit and ground.

Is the voltage above 4.8 volts?

Yes

- Repair the (P146) Passenger Mirror Position Sensor Supply circuit for an open to the mirror.
- Perform the VERIFICATION TEST. Body Verification Test.

No

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