B1395

DTC B1395

CIRCUIT DESCRIPTION
The power sliding door control module (PSDM) uses an optical sensor to monitor the power sliding door (PSD) position at all times. The optical sensor requires a 5-volt reference circuit and a reference return circuit, as well as a signal 1 and a signal 2 circuit. The output of the 5-volt reference circuit is normally between 4.5-5.5 volts.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC B1395 Device Voltage Reference Output Circuit

CONDITIONS FOR RUNNING THE DTC
A DTC B1395 may be set whenever the PSDM is powered up and has been commanded to operate the PSD.

CONDITIONS FOR SETTING THE DTC
The PSDM detects that the 5-volt reference output is not within the normal range of 4.5-5.5 volts.

ACTION TAKEN WHEN THE DTC SETS
- The PSDM sets DTC B1395.
- The corresponding PSD becomes inoperative.

CONDITIONS FOR CLEARING THE DTC
When the failure is no longer present and the DTC is cleared with the scan tool.

DIAGNOSTIC AIDS
- Inspect the optical sensor connector and terminals for damage.
- Inspect the optical sensor pigtail harness for damage.
- Inspect the optical sensor for proper installation and a secure mount to the actuator motor housing.

TEST DESCRIPTION

Step 1 - Step 7:

The numbers below refer to the step numbers on the diagnostic table.
2. This step tests the PSDM for the optical sensor 5-volt reference and ground.
6. The optical sensor needing replacement is part of the PSD motor/clutch assembly and is not serviced separately.
