B1D16

B1D16-PASSENGER MIRROR VERTICAL POSITION SENSOR INPUT CIRCUIT HIGH





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

- When Monitored:
Continuously.

- Set Condition:
The (P64) Passenger Mirror Vertical Position Signal circuit supplies input to the Passenger Door Module. The DTC B1D16 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. 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: B1D16-PASSENGER MIRROR VERTICAL 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 the BODY VERIFICATION TEST. Body Verification Test.

2. TEST FOR A SHORTED OUTSIDE REARVIEW MIRROR




1. Turn the ignition off.
2. Disconnect the Passenger Outside Rearview Mirror connector.
3. Connect a voltmeter between the (P64) Passenger Mirror Vertical Position Signal circuit and the (P66) Passenger 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 Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Above 5.2 volts

- Go To 3

Below 4.8 volts

- Go To 4

3. CHECK THE (P64) PASSENGER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE




1. Turn the ignition off.
2. Disconnect the Passenger Door Module C2 connector.
3. Turn the ignition on.
4. Measure the voltage of the (P64) Passenger Mirror Vertical Position Signal circuit.

Is the voltage above 0.2 volt?

Yes

- Repair the (P64) Passenger Mirror Vertical Position Signal circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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

4. CHECK THE (P64) PASSENGER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR AN OPEN




1. Turn the ignition off.
2. Disconnect the Passenger Door Module C2 connector.
3. Measure the resistance of the (P64) Passenger Mirror Vertical Position Signal circuit between the Passenger Outside Rearview Mirror connector and the Passenger Door Module C2 connector.

Is the resistance below 2.0 ohms?

Yes

- Go To 5

No

- Repair the (P64) Passenger Mirror Vertical Position Signal circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. CHECK THE (P66) PASSENGER MIRROR SENSOR GROUND CIRCUIT FOR AN OPEN




1. Measure the resistance of the (P66) Passenger Mirror Sensor Ground circuit between the Passenger Outside Rearview Mirror connector and the Passenger Door C2 Module connector.

Is the resistance below 2.0 ohms?

Yes

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

No

- Repair the (P66) Passenger Mirror Sensor Ground circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
