B1D1E
B1D1E-11-DRIVER MIRROR VERTICAL MOTOR CONTROL - CIRCUIT SHORT TO GROUND
For a complete wiring diagram, refer to the Wiring Information.
Theory of Operation
The Mirror Vertical Driver circuit supplies battery voltage for the mirror up position and ground for the mirror down position. The Mirror Common Driver supplies battery voltage for the mirror Down position and ground for the mirror up position.
- When Monitored:
Continuously.
- Set Condition:
The Door Module senses a short low on the (P71) Driver Mirror Vertical Driver circuit for more than two seconds.
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, 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.
Does the scan tool display: B1D1E-11-DRIVER MIRROR VERTICAL MOTOR 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, use the wiring diagram/schematic as a guide and inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
2. CHECK (P71) DRIVER MIRROR VERTICAL DRIVER CIRCUIT FOR A SHORT TO GROUND IN THE DOOR MODULE
NOTE: Here we are checking the Door Module for an internal short.
1. Disconnect the Driver Outside Rearview Mirror C1 and C2 harness connectors.
2. Using a scan tool, record and erase the Diagnostic Trouble Codes (DTCs).
3. Press and release the Mirror Select switch to select the Driver Outside Rearview Mirror.
4. 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.
NOTE: The scan tool will display several High or Open DTCs when the connectors are disconnected.
Does the scan tool display: B1D1E-11-DRIVER MIRROR VERTICAL MOTOR CONTROL - CIRCUIT SHORT TO GROUND as active?
Yes
- Replace the Driver Door Module. Door Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 3
3. CHECK (P71) DRIVER MIRROR VERTICAL DRIVER CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Measure the resistance between Ground and the (P71) Driver Mirror Vertical Driver circuit in the Driver Outside Rearview Mirror C2 (Component Side) connector.
Is the resistance below 10K Ohms?
Yes
- Repair the (P71) Driver Mirror Vertical Driver circuit for a short to ground. If the wiring harness and connector are okay, replace the Driver Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 4
4. CHECK (P71) DRIVER MIRROR VERTICAL DRIVER CIRCUIT FOR A SHORT TO ONE OF THE OTHER DRIVER MIRROR DRIVER CIRCUITS
1. Measure the resistance between the (P71) Driver Mirror Vertical Driver circuit (C2-6) and the other Driver Mirror Driver circuits in the Driver Outside Rearview Mirror C2 (Component Side) connector.
Is the resistance below 10.0 Ohms for either measurement?
Yes
- Repair all circuits with a resistance below 10.0 Ohms for a short to the (P71) Driver Mirror Vertical Driver circuit. If the wiring harness and connector are okay, replace the Driver Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 5
5. CHECK (P71) DRIVER MIRROR VERTICAL DRIVER CIRCUIT FOR A SHORT TO ANY RETURN OR GROUND CIRCUIT
1. Measure the resistance between the (P71) Driver Mirror Vertical Driver circuit (C2-6) and all Driver Mirror Ground or Return circuits in the Driver Outside Rearview Mirror C1 and C2 (Component Side) connectors.
Is the resistance below 10K Ohms between the (P71) Driver Mirror Vertical Driver circuit any of the Ground or Return circuits?
Yes
- Repair the (P71) Driver Mirror Vertical Driver circuit for a short to the Return or Ground circuit. If the wiring harness and connectors are okay, replace the Driver 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. Body Verification Test.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
