Diagnostic Test
- CHECK FOR AN ACTIVE DTC NOTE:
Before proceeding be sure this vehicle is equipped with Memory Mirrors and the configuration is set to = True.
- Turn the ignition on.
- Using a scan tool, record and erase the Diagnostic Trouble Codes (DTCs).
- Turn the passenger side turn signal on.
- Turn the approach lamps on, if equipped.
- Turn the rear defogger on, if equipped with heated mirror.
- Press and release the Mirror Select switch to select the Passenger Outside Rearview Mirror.
- Operate the Mirror Adjust Switch in all directions several times while monitoring the scan tool for DTCs in the PDM.NOTE:
After adjusting the mirror in one direction wait at least two seconds before adjusting the mirror in the opposite direction, as this will allow time for an active DTC to set, if present.
Is the DTC active?
Yes
- Go To 2
No
- The condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension and repair as necessary. If no problems are found, test complete.
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
- CHECK THE (A857) 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO BATTERY NOTE:
In this step we are measuring the 5-Volt Supply voltage at the Passenger Door Module. It should not be over 5.5 volts.
- Turn the ignition off.
- Disconnect the Passenger Outside Rearview Mirror C1 and C2 (Component Side) harness connectors from the Passenger Door Module C1 and C2 connectors.
- Turn the ignition on.
- Measure the voltage between Ground and the (A857) 5-volt Supply circuit at the Passenger Door Module connector.
Is the Voltage above 5.5 Volts?
Yes
- Replace the Passenger Door Module in accordance with Service Information. Refer to MODULE, DOOR (DDM/PDM), REMOVAL .
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Go To 3
- CHECK THE (A857) 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO ANOTHER SIGNAL OR DRIVER CIRCUITS NOTE:
We are now checking the wiring and the mirror for any crossed circuits.
- Turn the ignition off.
- Check for continuity between the (A857) 5-Volt Supply circuit and all Signal or Driver circuits in the Passenger Outside Rearview Mirror C1 and C2 (Component Side) harness connectors.
Is there continuity between the (A857) 5-Volt Supply circuit and any Signal or Driver circuit(s)?
Yes
- Repair the (A857) 5-Volt Supply circuit for a short to any Signal or Driver circuit(s).
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Go To 4
- CHECK THE (P64) PASSENGER MIRROR VERTICAL POSITION SIGNAL CIRCUIT FOR A SHORT TO ANOTHER SIGNAL OR DRIVER CIRCUITS
- Check for continuity between the (P64) Passenger Mirror Vertical Position Signal circuit and any Signal or Driver circuits in the Passenger Outside Rearview Mirror C1 and C2 (Component Side) harness connectors.
Is there continuity between the (P64) Passenger Mirror Vertical Position Signal circuit and any Signal or Driver circuit(s)?
Yes
- Repair the (P64) Passenger Mirror Vertical Position Signal circuit for a short to any Signal or Driver circuit(s).
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Go To 5
- Check for continuity between the (P64) Passenger Mirror Vertical Position Signal circuit and any Signal or Driver circuits in the Passenger Outside Rearview Mirror C1 and C2 (Component Side) harness connectors.
- CHECK (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR A SHORT TO ANY CIRCUIT DRIVER OR SIGNAL CIRCUITS
- Check for continuity between the (P68) Passenger Mirror Horizontal Position Signal circuit and any Signal or Driver circuits in the Passenger Outside Rearview Mirror C1 and C2 (Component Side) harness connectors.
Is there continuity between the (P68) Passenger Mirror Horizontal Position Signal circuit and any Signal or Driver circuit(s)?
Yes
- Repair the (P68) Passenger Mirror Horizontal Position Signal circuit for a short to any Signal or Driver circuit(s).
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Replace the Passenger Door Module in accordance with Service Information. Refer to MODULE, DOOR (DDM/PDM), REMOVAL .
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
- Check for continuity between the (P68) Passenger Mirror Horizontal Position Signal circuit and any Signal or Driver circuits in the Passenger Outside Rearview Mirror C1 and C2 (Component Side) harness connectors.
