B1D10(DDM), B1D19(PDM) - MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT HIGH

B1D10(DDM), B1D19(PDM) - Mirror Horizontal Position Sensor Input Circuit High:

WHEN MONITORED
Continuously

SET CONDITION
The (P65) Driver Mirror Horizontal Position Signal circuit supplies input to the Driver Door Module. DTC B1D10 will set if the input value is greater than the known good (stored) value for more than 60 ms.
The (P68) Passenger Mirror Horizontal Position Signal circuit supplies input to the Passenger Door Module. DTC B1D19 will set if the input value is greater than the known good (stored) value for more than 60 ms.

POSSIBLE CAUSES
- FOR THE DRIVER MEMORY MIRROR SYSTEM:
- (P65) driver mirror horizontal position signal circuit shorted to voltage
- (P65) driver mirror horizontal position signal circuit open
- (P69) driver mirror sensor ground circuit open
- Driver outside rearview mirror shorted
- Driver door module

- FOR THE PASSENGER MEMORY MIRROR SYSTEM:
- (P68) passenger mirror horizontal position signal circuit shorted to voltage
- (P68) passenger mirror horizontal position signal circuit open
- (P66) passenger mirror sensor ground circuit open
- Passenger outside rearview mirror shorted
- Passenger door module

NOTE: This procedure addresses the Driver Memory Mirror system's circuits and components and the Passenger Memory Mirror system's circuits and components. Select only that which applies to the system you are diagnosing.

DIAGNOSTIC TEST

1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTCs.
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 DTCs.

Q: Does the scan tool display: B1D10 or B1D19 MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT HIGH?

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 OUTSIDE REARVIEW MIRROR




For the Driver Memory Mirror System, proceed as follows:
- Turn the ignition off.
- Disconnect the Driver Outside Rearview Mirror connector.
- Connect a voltmeter between the (P65) Driver Mirror Horizontal Position Signal circuit and the (P69) Driver Mirror Sensor Ground circuit.
- Turn the ignition on.
- Move the mirror switch to any switch position while monitoring the voltmeter.

For the Passenger Memory Mirror System, proceed as follows:
- Turn the ignition off.
- Disconnect the Passenger Outside Rearview Mirror connector.
- Connect a voltmeter between the (P68) Passenger Mirror Horizontal Position Signal circuit and the (P66) Passenger Mirror Sensor Ground circuit
- Turn the ignition on.
- Move the mirror switch to any switch position while monitoring the voltmeter.

Q: What is the voltage?

4.8 to 5.2 volts
Replace the Outside Rearview Mirror.
Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

Above 5.2 volts
Go To 3

Below 4.8 volts
Go To 4

3. CHECK THE (P65) DRIVER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT OR THE (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE




For the Driver Memory Mirror System, proceed as follows:
- Turn the ignition off.
- Disconnect the Driver Door Module C2 connector.
- Turn the ignition on.
- Measure the voltage of the (P65) Driver Mirror Horizontal Position Signal circuit.

For the Passenger Memory Mirror System, proceed as follows:
