For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Continuously.

- Set Condition:
The Door Module senses an open or a short high on the (C17) Passenger Mirror Heater Driver circuit for more than two seconds.





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.

Is the DTC 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.

Is the DTC 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, use the wiring diagram/schematic as a guide and inspect the wiring and connectors.
- 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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. CHECK (C17) PASSENGER MIRROR HEATER DRIVER CIRCUIT AND (C170) PASSENGER MIRROR HEATER RETURN CIRCUIT FOR AN OPEN




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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. CHECK (C17) PASSENGER MIRROR HEATER DRIVER CIRCUIT FOR A SHORT TO (P74) PASSENGER MIRROR HORIZONTAL DRIVER CIRCUIT, (P72) PASSENGER MIRROR VERTICAL DRIVER CIRCUIT, OR TO (P70) PASSENGER MIRROR COMMON DRIVER CIRCUIT




1. Measure the resistance between the (C17) Passenger Mirror Heater Driver circuit and the (P74) Passenger Mirror Horizontal Driver circuit at the Passenger Outside Rearview Mirror C2 (Component Side) connector.
2. Measure the resistance between the (C17) Passenger Mirror Heater Driver circuit and the (P72) Passenger Mirror Vertical Driver circuit at the Passenger Outside Rearview Mirror C2 (Component Side) connector.
3. Measure the resistance between the (C17) Passenger Mirror Heater Driver circuit and the (P70) Passenger Mirror Common Driver circuit at 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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No, with Turn Signal Mirror

- Go To 6

No, without Turn Signal Mirror

- Go To 7

6. CHECK (C17) PASSENGER MIRROR HEATER DRIVER CIRCUIT FOR A SHORT TO (P502) PASSENGER MIRROR TURN SIGNAL DRIVER CIRCUIT




1. Measure the resistance between the (C17) Passenger Mirror Heater Driver circuit 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 (C17) Passenger Mirror Heater Driver circuit 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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No, with Puddle Lamp Mirror

- Go To 7

No, without Puddle Lamp Mirror

- Inspect the wiring and connectors for damage and repair as necessary. If the wiring and connectors are okay, replace the Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

7. CHECK (C17) PASSENGER MIRROR HEATER DRIVER CIRCUIT FOR A SHORT TO (M42) PASSENGER PUDDLE LAMP DRIVER 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 and the (M42) Passenger Puddle Lamp Driver circuit at the Passenger Outside Rearview Mirror C2 and C1 (Component Side) connectors.

Is the resistance below 10K Ohms?

Yes

- Repair the (C17) Passenger Mirror Heater Driver circuit for a short to the (M42) Passenger Puddle Lamp Driver circuit. If the wiring harness and connector are okay, replace the Passenger Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
