Diagnostic Test

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: B1D19-PASSENGER MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT HIGH?
  
  Yes
  - Go to step 2
  No
  - The conditions that caused this code to set are not present at this time. Using the SYSTEM WIRING DIAGRAMS as a guide, inspect the wiring and connectors.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .

1. Turn the ignition off.
2. Disconnect the Passenger Outside Rearview Mirror connector.
3. Connect a voltmeter between the (P68) Passenger Mirror Horizontal 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 in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
  Above 5.2 volts
  - Go to step 3
  Below 4.8 volts
  - Go to step 4
