B3260

DTC B3260

CIRCUIT DESCRIPTION
The power sliding door (PSD) latch/unlatch motor/actuator is responsible for latching and unlatching the PSD when the power sliding door control module (PSDM) has received a request to open or close the door. The latch/unlatch motor/actuator receives battery positive voltage from the PSDM via the PSD latch/unlatch motor/actuator control circuit. Ground is supplied to the motor/actuator via G301 for the left side sliding door and G302 for the right side sliding door. The PSDM monitors the voltage on the latch/unlatch motor/actuator control circuit during latching and unlatching operations in order to determine when a failure has occurred.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC B3260 Power Sliding Door Secondary Latch Circuit

CONDITIONS FOR SETTING THE DTC
The PSD latch/unlatch motor/actuator circuit is open, short to ground, or short to battery while the PSDM is attempting to latch or unlatch the door.

ACTION TAKEN WHEN THE DTC SETS
The PSDM sets DTC B3260.

CONDITIONS FOR CLEARING THE DTC
When the failure is no longer present.

DIAGNOSTIC AIDS
- Inspect the PSD contact plungers and corresponding B-pillar contact plate pads for the following conditions prior to performing the test steps:
- Proper door plunger operation.
- Clean electrical contact from the door plungers to the B-pillar contact pads.
- Proper alignment of the door plungers to the B-pillar contact pads.
- While performing step 2 of the procedure, close the PSD only by manual operation. The PSD may re-open without being commanded if any other method is used to close the door.
- While performing both steps 2 and 3 of the procedure, follow the guidelines listed below in order to ensure accurate test results:
- Disable the PSD at the multifunction switch
- Manually close the door
- Use the keyless entry transmitter to open the door

TEST DESCRIPTION

Step 1 - Step 12:

Step 13:

The numbers below refer to the step numbers on the diagnostic table.
2. This step verifies that the latch/unlatch motor/actuator control circuit within the PSDM is Inactive when the door is closed. In this mode, no voltage is applied to the circuit.
3. This step verifies that the PSDM can switch the control circuit from an Inactive state to an Active state. In the Active mode, the PSDM applies battery voltage to the circuit.
