B1395

DTC B1395

DTC Descriptor
DTC B1395
- Device Voltage Reference Output Circuit

Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview

Circuit/System 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.

Conditions for Running the DTC

A DTC B1395 may be set whenever the PSDM is powered up and has been commanded to operate the power sliding door.

Conditions for Setting the DTC

B1395

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 affected power sliding door will not operate.
* The PSDM sets a DTC B1395.

Conditions for Clearing the DTC

* This DTC will change from current to history when the fault is no longer present.
* The technician issues a scan tool CLEAR DTCs command.


Circuit/System Verification

Ignition ON, command the appropriate power sliding door to UNLATCH, OPEN, CLOSE and LATCH with a scan tool. The appropriate power sliding door should unlatch, open, close and latch.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector C2 at the appropriate Sliding Door Module.
2. Ignition ON, test for 4.5-5.5 volts between the Sliding Door Sensor Voltage Reference circuit terminal 12 and ground.

• If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the appropriate Sliding Door Module.
• If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the appropriate Sliding Door Module.
