B1D16

B1D0D(DDM), B1D16(PDM) - MIRROR VERTICAL POSITION SENSOR INPUT CIRCUIT HIGH





For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

Continuously

- Set Condition:

The (P67) Driver Mirror Vertical Position Signal circuit supplies input to the Driver Door Module. DTC B1D0D will set if the input value is greater than the known good (stored) value for more than 60 ms.

The (P64) Passenger Mirror Vertical Position Signal circuit supplies input to the Passenger Door Module. DTC B1D16 will set if the input value is greater than the known good (stored) value for more than 60 ms.





NOTE: This procedure addresses the Driver Memory Mirror system's circuits and components and the Passenger Memory Mirror system's circuits and components. Select only that which applies to the system you are diagnosing.

Diagnostic Test

1.TEST FOR INTERMITTENT CONDITION

Turn the ignition on.

With the scan tool, record and erase DTCs.

Operate the Mirror Switch in all directions several times.

Cycle the ignition from on to off 3 times.

Turn the ignition on.

With the scan tool, read DTCs.

Does the scan tool display: B1D0D or B1D16 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 BODY VERIFICATION TEST - VER 1. Body Verification Test

2.TEST FOR A SHORTED OUTSIDE REARVIEW MIRROR





For the Driver Memory Mirror System, proceed as follows:
- Turn the ignition off.
- Disconnect the Driver Outside Rearview Mirror connector.
- Connect a voltmeter between the (P67) Driver Mirror Vertical Position Signal circuit and the (P69) Driver Mirror Sensor Ground circuit.
- Turn the ignition on.
- Move the mirror switch to any switch position while monitoring the voltmeter.

For the Passenger Memory Mirror System, proceed as follows:
- Turn the ignition off.
- Disconnect the Passenger Outside Rearview Mirror connector.
- Connect a voltmeter between the (P64) Passenger Mirror Vertical Position Signal circuit and the (P66) Passenger Mirror Sensor Ground circuit
- Turn the ignition on.
- 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 BODY VERIFICATION TEST - VER 1. Body Verification Test

Above 5.2 Volts

- Go To 3

Below 4.8 Volts

- Go To 4

3.CHECK THE (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL CIRCUIT OR THE (P64) PASSENGER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE





For the Driver Memory Mirror System, proceed as follows:
- Turn the ignition off.
- Disconnect the Driver Door Module C2 connector.
- Turn the ignition on.
- Measure the voltage of the (P67) Driver Mirror Vertical Position Signal circuit.

For the Passenger Memory Mirror System, proceed as follows:
- Turn the ignition off.
- Disconnect the Passenger Door Module C2 connector.
- Turn the ignition on.
- Measure the voltage of the (P64) Passenger Mirror Vertical Position Signal circuit.

No, Driver Mirror

- Replace the Driver Door Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No, Passenger Mirror

- Replace the Passenger Door Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

4.CHECK THE (P67) DRIVER MIRROR VERTICAL POSITION SIGNAL CIRCUIT OR THE (P64) PASSENGER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR AN OPEN





For the Driver Memory Mirror System, proceed as follows:
- Turn the ignition off.
- Disconnect the Driver Door Module C2 connector.
- Measure the resistance of the (P67) Driver Mirror Vertical Position Signal circuit between the Driver Outside Rearview Mirror connector and the Driver Door Module C2 connector.

For the Passenger Memory Mirror System, proceed as follows:
- Turn the ignition off.
- Disconnect the Passenger Door Module C2 connector.
- 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, Driver Mirror

- Repair the (P67) Driver Mirror Vertical Position Signal circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No, Passenger Mirror

- Repair the (P64) Passenger Mirror Vertical Position Signal circuit for an open.
