B164E-11
B164E-11-PASSENGER MIRROR SIGNAL LAMP CONTROL - CIRCUIT SHORT TO GROUND
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
Continuously.
- Set Condition:
The Door Module senses a short low on the (P502) Passenger Mirror Turn Signal Driver circuit for more than two seconds with the turn signal switched on.
1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. Using a scan tool, record and erase Diagnostic Trouble Codes (DTCs).
3. Turn the passenger side turn signal on.
4. Turn the approach lamps on, if equipped.
5. Turn the rear defogger on, if equipped with heated mirror.
6. Press and release the Mirror Select switch to select the Passenger Outside Rearview Mirror.
7. Operate the Mirror Adjust switch in all directions several times while monitoring the scan tool for DTCs.
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 fault to set if present.
Is the DTC active?
Yes
- Go To 2
No
- The conditions that caused this code to set are not present at this time. For vehicle's equipped with folding outside rearview mirrors, repeat test with mirror folded. If DTC is now active, Go To 2. For others, 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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
2. CHECK (P502) PASSENGER MIRROR TURN SIGNAL DRIVER CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the Passenger Outside Rearview Mirror C2 (Component Side) connector from the Door Module C2 connector.
3. Measure the resistance between ground and the (P502) Passenger Mirror Turn Signal Driver circuit at the Passenger Outside Rearview Mirror C2 (Component Side) connector.
Is the resistance below 10K Ohms?
Yes
- Repair the (P502) Passenger Mirror Turn Signal Driver circuit for a short to ground. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 3
3. CHECK (P502) PASSENGER MIRROR TURN SIGNAL DRIVER CIRCUIT SHORTED TO A PASSENGER MIRROR DRIVER CIRCUIT
1. Measure the resistance between the (P502) Passenger Mirror Turn Signal Driver circuit (C2-9) and each Passenger Mirror Driver circuit in the Passenger Outside Rearview Mirror C2 (Component Side) connector.
Is the resistance below 10K Ohms for any measurement?
Yes
- Repair all circuits with a resistance below 10K Ohms for a short to the (P502) Passenger Mirror Turn Signal Driver circuit. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 4
4. CHECK (P502) PASSENGER MIRROR TURN SIGNAL DRIVER CIRCUIT FOR A SHORT TO THE (P595) PASSENGER MIRROR TURN SIGNAL LAMP RETURN CIRCUIT
NOTE: The Ohmmeter positive lead must be connected to the (P595) Passenger Mirror Turn Signal Return circuit and the negative lead to the (P502) Passenger Mirror Turn Signal Driver circuit for the test results to be valid.
1. Measure the resistance between the (P502) Passenger Mirror Turn Signal Driver circuit and the (P595) Passenger Mirror Turn Signal Return circuit at the Passenger Outside Rearview Mirror C2 (Component Side) connector.
Is the resistance below 200.0 Ohms?
Yes
- Repair the (P502) Passenger Mirror Turn Signal Driver circuit for a short to the (P595) Passenger Mirror Turn Signal Return circuit. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 5
5. CHECK (P502) PASSENGER MIRROR TURN SIGNAL DRIVER CIRCUIT FOR A SHORT TO ANY SENSOR GROUND OR RETURN CIRCUIT
1. Measure the resistance between the (P502) Passenger Mirror Turn Signal Driver circuit (C2-9) and all sensor ground and return circuits.
Is the resistance below 10K Ohms for any measurement?
Yes
- Repair the (P502) Passenger Mirror Turn Signal Driver circuit for a short to a sensor ground or return circuit. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Inspect the wiring and connectors for damage and repair as necessary. If the wiring and connectors are okay, replace the Door Module. Door Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
