B1D36-11-PASSENGER MIRROR HEATER 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 (C17) Passenger Mirror Heater Driver circuit for more than two seconds with the heater 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 turn signal on, if equipped with turn signal mirror.
4. Turn the puddle lamps on, if equipped with puddle lamp mirror.
5. Turn the rear defogger on.
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.
Does the scan tool display: B1D36-11-PASSENGER MIRROR HEATER CONTROL - CIRCUIT SHORT TO GROUND as 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. Otherwise, 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 poor pin fit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
2. CHECK (C17) PASSENGER MIRROR HEATER 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 of the (C17) Passenger Mirror Heater Driver circuit between ground and the Passenger Outside Rearview Mirror C2 (Component Side) connector.
Is the resistance below 10K Ohms?
Yes
- Repair the (C17) Passenger Mirror Heater 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 (C17) PASSENGER MIRROR HEATER DRIVER CIRCUIT FOR A SHORT TO A PASSENGER MIRROR DRIVER CIRCUIT
1. Measure the resistance between the (C17) Passenger Mirror Heater Driver circuit (C2-4) and all Passenger Mirror Driver circuits 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 (C17) Passenger Mirror Heater 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 (C17) PASSENGER MIRROR HEATER DRIVER CIRCUIT FOR A SHORT TO (C170) PASSENGER MIRROR HEATER RETURN CIRCUIT
1. Measure the resistance between the (C17) Passenger Mirror Heater Driver circuit and the (C170) Passenger Mirror Heater Return circuit at the Passenger Outside Rearview Mirror C2 (Component Side) connector.
Is the resistance below 3.0 Ohms?
Yes
- Repair the (C17) Passenger Mirror Heater Driver circuit for a short to the (C170) Passenger Mirror Heater 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 (C17) PASSENGER MIRROR HEATER DRIVER CIRCUIT FOR A SHORT TO ANY PASSENGER MIRROR GROUND OR RETURN CIRCUIT
1. Disconnect the Passenger Outside Rearview Mirror C1 (Component Side) connector from the Door Module C1 connector.
2. Measure the resistance between the (C17) Passenger Mirror Heater Driver circuit (C2-4) and each Passenger Mirror Ground and Return circuits in the Passenger Outside Rearview Mirror C2 and C1 (Component Side) connectors.
Is the resistance below 10K Ohms between the (C17) Passenger Mirror Heater Driver circuit and any Ground or Return circuit?
Yes
- Repair the (C17) Passenger Mirror Heater Driver circuit for a short to the Passenger Mirror 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.
