B1D10

B1D10-MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT HIGH






WHEN MONITORED
Continuously

SET CONDITION
When the Driver/Passenger Door Module senses greater than 4.8 volts on the Mirror Horizontal Position Signal circuit for over 100 ms, this code will set.

NOTE: This test covers both the Driver and Passenger code depending on the side of the code appeared in.

POSSIBLE CAUSES
- (P65) or (P68) mirror horizontal position signal circuit short to voltage
- (P69) or (P66) mirror sensor ground circuit open
- 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
With the scan tool, monitor the Mirror Horizontal Position Sense voltage and operate the mirror switch and any optional features located in the mirror to see if any time the voltage is over 4.8 volts.
Cycle the ignition from Off to On three times and leave On.
With the scan tool, read DTC's.

Q: Does the scan tool display B1D10-MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT HIGH or is or did the sense voltage go over 4.8 volts?

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.

2. TEST FOR A SHORTED MIRROR

Disconnect the appropriate mirror connector.
With the scan tool, erase DTC's.
With the scan tool, monitor the Mirror Horizontal Position Sense voltage and operate the mirror switch and any optional features.
Cycle the ignition from Off to On three times and leave On.
With the scan tool, read DTC's.

Q: Does the scan tool display the same DTC or is or did the sense voltage go over 4.8 volts?

NO: Go To 3
YES: Go to 4

3. TEST THE (P69) MIRROR SENSOR GROUND WIRE FOR AN OPEN






Measure the resistance between the (P69) Mirror Sensor Ground and the Ground circuit in the Mirror connector.

Q: Is the resistance below 2.0 Ohms?

NO: Check and repair the (P69) Mirror Sensor Ground circuit for an open from the mirror connector to the module connector, if OK replace the appropriate Door Module.
Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

YES: Replace the Mirror.

4. TEST THE (P65) MIRROR HORIZONTAL POSITION SIGNAL WIRE FOR A SHORT TO VOLTAGE CONDITION






Turn the ignition off.
Disconnect the vehicles negative battery cable.
Disconnect the Driver Door Module C4 connector.
Measure the resistance between the (P65) Mirror Horizontal Position Signal wire to other wires in the Door Module C4 connector.

Q: Is the resistance below 5000.0 Ohms?

NO: Repair the (P65) Mirror Horizontal Position Signal wire for a short to another wire.
