1. TEST FOR INTERMITTENT CONDITION - HEATER OFF
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. Press and release the Mirror Select switch to select the Passenger Outside Rearview Mirror.
6. 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; B1D36-15-PASSENGER MIRROR HEATER CONTROL - CIRCUIT SHORT TO BATTERY OR OPEN as active?

Yes

- Go To 3

No

- Go To 2

2. TEST FOR INTERMITTENT CONDITION - HEATER ON
1. Turn the rear defogger on.
2. 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; B1D36-15-PASSENGER MIRROR HEATER CONTROL - CIRCUIT SHORT TO BATTERY OR OPEN as active?

Yes

- Go To 3

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 3. 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.

3. CHECK (C17) PASSENGER MIRROR HEATER DRIVER CIRCUIT FOR A SHORT TO VOLTAGE




1. Turn the ignition off.
2. Disconnect the Passenger Outside Rearview Mirror C2 (Component Side) connector from the Door Module C2 connector.
3. Turn the ignition on.
4. Measure the voltage of the (C17) Passenger Mirror Heater Driver circuit between the Passenger Outside Rearview Mirror C2 (Component Side) connector and ground.

Is there any voltage present?

Yes

- Repair the (C17) Passenger Mirror Heater Driver circuit for a short to voltage. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.

1. Turn the ignition off.
2. 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 9.0 Ohms?

Yes

- Go To 5

No

- Repair the (C17) Passenger Mirror Heater Driver circuit or the (C170) Passenger Mirror Heater Return circuit for an open. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.

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 6

6. CHECK (C17) PASSENGER MIRROR HEATER DRIVER CIRCUIT FOR A SHORT TO ALL OTHER PASSENGER MIRROR DRIVER CIRCUITS




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 all other Passenger Mirror Driver 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 Passenger Mirror Driver circuit?

Yes

- Repair the short between the (C17) Passenger Mirror Heater Driver circuit and the other Passenger Mirror Driver circuits. 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.
