B164A-15

B164A-15-DRIVER MIRROR SIGNAL LAMP CONTROL - CIRCUIT SHORT TO BATTERY OR OPEN







- When Monitored:
Continuously.

- Set Condition:
The Door Module senses current greater than 100 mA or an open on the (P501) Driver 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 turn signal on.
4. Turn the puddle lamps on, if equipped with puddle lamp mirror.
5. Turn the rear defogger on, if equipped with heated mirror.
6. Press and release the Mirror Select switch to select the Driver 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. Otherwise, use the wiring diagram/schematic as a guide and inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK (P501) DRIVER MIRROR TURN SIGNAL DRIVER CIRCUIT FOR A SHORT TO VOLTAGE




1. Turn the ignition off.
2. Disconnect the Driver Outside Rearview Mirror C2 (Component Side) connector from the Door Module C2 connector.
3. Turn the ignition on.
4. Measure the voltage of the (P501) Driver Mirror Turn Signal Driver circuit between the Driver Outside Rearview Mirror C2 (Component Side) connector and ground.

Is there any voltage present?

Yes

- Repair the (P501) Driver Mirror Turn Signal Driver circuit for a short to voltage. If the wiring harness and connector are okay, replace the Driver Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. CHECK (P501) DRIVER MIRROR TURN SIGNAL DRIVER CIRCUIT FOR A SHORT TO THE (P71) DRIVER MIRROR VERTICAL DRIVER CIRCUIT, (P73) DRIVER MIRROR COMMON DRIVER CIRCUIT, OR TO THE (P75) DRIVER MIRROR HORIZONTAL DRIVER CIRCUIT




1. Turn the ignition off.
2. Measure the resistance between the (P501) Driver Mirror Turn Signal Driver circuit and the (P71) Driver Mirror Vertical Driver circuit at the Driver Outside Rearview Mirror C2 (Component Side) connector.
3. Measure the resistance between the (P501) Driver Mirror Turn Signal Driver circuit and the (P73) Driver Mirror Common Driver circuit at the Driver Outside Rearview Mirror C2 (Component Side) connector.
4. Measure the resistance between the (P501) Driver Mirror Turn Signal Driver circuit and the (P75) Driver Mirror Horizontal Driver circuit at the Driver 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 (P501) Driver Mirror Turn Signal Driver circuit. If the wiring harness and connector are okay, replace the Driver Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No, with Heated Mirror

- Go To 4

No, without Heated Mirror

- Go To 5

4. CHECK (P501) DRIVER MIRROR TURN SIGNAL DRIVER CIRCUIT FOR A SHORT TO THE (C16) DRIVER MIRROR HEATER DRIVER CIRCUIT




1. Measure the resistance between the (P501) Driver Mirror Turn Signal Driver circuit and the (C16) Driver Mirror Heater Driver circuit at the Driver Outside Rearview Mirror C2 (Component Side) connector.

Is the resistance below 10K Ohms?

Yes

- Repair the (P501) Driver Mirror Turn Signal Driver circuit for a short to the (C16) Driver Mirror Heater Driver circuit. If the wiring harness and connector are okay, replace the Driver Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 5

5. CHECK (P501) DRIVER MIRROR TURN SIGNAL DRIVER CIRCUIT AND (P593) DRIVER MIRROR TURN SIGNAL RETURN CIRCUIT FOR AN OPEN





NOTE: The Ohmmeter positive lead must be connected to the (P501) Driver Mirror Turn Signal Driver circuit and the negative lead to the (P593) Driver Mirror Turn Signal Return circuit for the test results to be valid.

1. Measure the resistance between the (P501) Driver Mirror Turn Signal Driver circuit and the (P593) Driver Mirror Turn Signal Return circuit at the Driver Outside Rearview Mirror C2 (Component Side) connector.

Is the resistance above 1K Ohm?

Yes

- Repair the (P501) Driver Mirror Turn Signal Driver circuit or the (P593) Driver Mirror Turn Signal Return circuit for an open. If the wiring harness and connector are okay, replace the Driver Outside Rearview Mirror.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No, with Puddle Lamp Mirror

- Go To 6

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.

6. CHECK (P501) DRIVER MIRROR TURN SIGNAL DRIVER CIRCUIT FOR A SHORT TO THE (M41) DRIVER PUDDLE LAMP DRIVER CIRCUIT




1. Disconnect the Driver Outside Rearview Mirror C1 (Component Side) connector from the Door Module C1 connector.
2. Measure the resistance between the (P501) Driver Mirror Turn Signal Driver circuit and the (M41) Driver Puddle Lamp Driver circuit at the Driver Outside Rearview Mirror C2 and C1 (Component Side) connectors.

Is the resistance below 10K Ohms?

Yes

- Repair the (P501) Driver Mirror Turn Signal Driver circuit for a short to the (M41) Driver Puddle Lamp Driver circuit. If the wiring harness and connector are okay, replace the Driver Outside Rearview Mirror.
- 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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
