B1D22,B1D2E-MIRROR HORIZONTAL MOTOR CONTROL CIRCUIT/PERFORMANCE - DOOR MODULEB1D22,B1D2E-Mirror Horizontal Motor Control Circuit/Performance - Door Module:
WHEN MONITORED
Continuously
SET CONDITION
When the Driver/Passenger Door Module senses a value below the tolerance of the mirror motor on the Mirror Horizontal Motor Driver circuit for over 10ms., this code will set.
NOTE: This test covers both the Driver and Passenger code depending on the side the code appeared in.
POSSIBLE CAUSES
- (P75) or (P74) mirror horizontal driver circuit short to ground
- (P75) or (P74) mirror horizontal driver circuit shorted to the (Z912) or (Z911) ground circuit.
- Mirror shorted
- Driver/passenger door module
DIAGNOSTIC TEST
1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTC's
Operate the Mirror Switch in all directions several times.
Cycle the ignition from on to off 3 times.
Turn the ignition on.
With the scan tool, read DTC's.
Q: Does the scan tool display B1D22 or B1D2E-MIRROR HORIZONTAL MOTOR CONTROL CIRCUIT/PERFORMANCE?
YES: Go To 2
NO: The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
2. TEST FOR A SHORTED MIRROR
Disconnect the appropriate mirror connector.
With the scan tool, erase DTC's.
Operate the Mirror Switch in all directions several times.
Cycle the ignition from on to off 3 times.
Turn the ignition on.
With the scan tool, read DTC's.
Q: Does the scan tool display B1D22 or B1D2E-MIRROR HORIZONTAL MOTOR CONTROL CIRCUIT/PERFORMANCE?
NO: Replace the Mirror. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
YES: Go to 3
3. TEST THE (P75) OR (P74)) MIRROR HORIZONTAL MOTOR DRIVER WIRE FOR A SHORT TO GROUND
Turn the ignition off.
Disconnect the appropriate Door Module C4 connector.
Measure the resistance between ground and the (P75) or (P74) Mirror Horizontal Motor Driver circuit.
Q: Is the resistance below 5000.0 ohms?
YES: Repair the (P75) or (P74) Mirror Horizontal Motor Driver circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go to 4
4. TEST THE (P75) OR (P74) MIRROR HORIZONTAL MOTOR DRIVER CIRCUIT SHORTED TO THE (Z912) OR (Z911) GROUND CIRCUIT.
Measure the resistance between the (P75) or (P74) Mirror Horizontal Driver circuit and the (Z912) or (Z911) Ground circuit.
Q: Is the resistance below 5000.0 ohms?
YES: Repair the (P75) or (P74) Mirror Horizontal Motor Driver circuit for a short to the (Z912) or (Z911) Mirror Heater Ground Circuit. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace the appropriate Door Module. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
