Diagnostic Test

  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: B1D09-DRIVER MIRROR POSITION SENSOR POWER SUPPLY CIRCUIT LOW?

      Yes 

      • Go to step  2

      No 

  2. TEST FOR A SHORTED OUTSIDE REARVIEW MIRROR

    1. Turn the ignition off.
    2. Disconnect the Driver Outside Rearview Mirror connector.
    3. Turn the ignition on.
    4. Measure the voltage between the (P669) Driver Mirror Sensor Supply circuit and the (P69) Driver Mirror Sensor Ground circuit.

      Is the voltage above 4.6 volts?

      Yes 

      No 

      • Go to step  3
  3. CHECK THE (P669) DRIVER MIRROR SENSOR SUPPLY CIRCUIT FOR A SHORT TO GROUND

    1. Turn the ignition off.
    2. Disconnect the Driver Door Module C2 connector.
    3. Measure the resistance between ground and the (P669) Driver Mirror Sensor Supply circuit in the Driver Door Module C2 connector.

      Is the resistance below 10k ohms?

      Yes 

      No 

      • Go to step  4
  4. CHECK THE (P669) DRIVER MIRROR SENSOR SUPPLY CIRCUIT FOR A SHORT TO THE (Z911) GROUND CIRCUIT

    1. Measure the resistance between the (P669) Driver Mirror Sensor Supply circuit and the (Z911) Ground circuit in the Driver Door Module C2 connector.

      Is the resistance below 10k ohms?

      Yes 

      No 

      • Go to step  5
  5. CHECK THE (P669) DRIVER MIRROR SENSOR SUPPLY CIRCUIT FOR A SHORT TO THE (P69) DRIVER MIRROR SENSOR GROUND CIRCUIT

    1. Measure the resistance between the (P669) Driver Mirror Sensor Supply circuit and the (P69) Driver Mirror Sensor Ground circuit in the Driver Door Module C2 connector.

      Is the resistance below 10k ohms?

      Yes 

      No 

      • Go to step  6
  6. CHECK THE (P669) DRIVER MIRROR SENSOR SUPPLY CIRCUIT FOR A SHORT TO THE (C910) DRIVER MIRROR HEATER RETURN CIRCUIT
