B1D18
B1D0F,B1D18-MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT LOW - DOOR MODULEB1D0F,B1D18-Mirror Horizontal Position Sensor Input Circuit Low - Door Module:
WHEN MONITORED
Continuously
SET CONDITION
When the Driver/Passenger Door Module senses a value below the parameter of the mirror sensor on the Mirror Horizontal Position Signal circuit for over 60ms., this code will set.
NOTE: This test covers both the Driver and Passenger code depending on the side the code appeared in.
POSSIBLE CAUSES
- (P65) or (P68) mirror horizontal position signal circuit short to ground
- (P65) or (P68) mirror horizontal position signal circuit shorted to (P69) or (P66) mirror sensor 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 B1D0F or B1D18-MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT LOW?
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 B1D0F or B1D18-MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT LOW?
NO: Replace the Mirror. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
YES: Go to 3
3. TEST THE (P65) OR (P68) MIRROR HORIZONTAL POSITION SIGNAL WIRE FOR A SHORT TO GROUND
Turn the ignition off.
Disconnect the appropriate Door Module C4 connector.
Measure the resistance between ground and the (P65) or (P68) Mirror Horizontal Position Signal circuit.
Q: Is the resistance below 5000.0 ohms?
YES: Repair the (P65) or (P68) Mirror Horizontal Position Signal circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go to 4
4. TEST THE (P65) OR (P68) MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT SHORTED TO THE (P69) OR (P66) MIRROR SENSOR GROUND CIRCUIT.
Measure the resistance between the (P65) or (P68) Mirror Horizontal Position Signal circuit and the (P69) or (P66) Mirror Sensor Ground circuit.
Q: Is the resistance below 5000.0 ohms?
YES: Repair the (P65) or (P68) Mirror Horizontal Position Signal circuit for a short to the (P69) or (P66) Sensor 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
