### Circuit Description

The Power Sliding Door (PSD) contains an optical sensor that provides sliding door position information to the rear side door actuator control module. The optical sensor sends pulses to the rear side door actuator control module when the sliding door is moving. The rear side door actuator control module keeps track of these optical sensor pulses at all times, even when the sliding door is open or closed manually with the power sliding door on/off switch in the off position. The optical sensor pulses allow the rear side door actuator control module to calculate the position of the sliding door. Also, the optical sensor allows the rear side door actuator control module to resume PSD operation after operating the sliding door manually.

In addition to the optical sensor, the rear side door actuator control module uses the PSD detent switch to determine when the sliding door is open, ajar, or latched. The PSD detent switch is part of the sliding door latch assembly. The PSD detent switch sends ground signals to the rear side door actuator control module through circuit 1892 indicating when the sliding door is open, ajar, or latched (fully closed). The PSD detent switch receives ground through circuit 750. Circuits 750 and 1892 pass through the switch plate plungers and pads located on the B-pillar.

When the PSD is closing and the sliding door is about 30 cm (12 in.) from being closed, the rear side door actuator control module reduces power to the cable motor. This action slows down the movement of the sliding door. Once the switch plate plungers and pads make contact, circuits 750 and 1892 are completed and the rear side door actuator control module is able to monitor the PSD detent switch input.

When the sliding door latch moves from the open to the secondary latch (ajar) position, the PSD detent switch no longer sends a ground signal to the rear side door actuator control module, thus opening circuit 1892. This action signals the rear side door actuator control module that the sliding door has passed from the open door to the secondary latch (ajar) position. Upon detecting the door ajar position, the rear side door actuator control module sends full power to the cable motor.

As the sliding door continues to close, the sliding door latch moves from the ajar to the primary latch position. The PSD detent switch sends and another ground signal to the rear side door actuator control module when the sliding door is between the secondary and primary latch position. This action signals the rear side door actuator control module that the sliding door has passed from ajar to door closed position. Then, the rear side door actuator control module disengages the clutch and de-energizes the cable motor.

### Conditions for Setting the DTC

The PSD is unable to determine the exact location of the sliding door due to a problem with one of the following inputs:

• | The optical sensor input

• | The PSD detent switch input

### Action Taken When the DTC Sets

• | The PSD is disabled.

• | Any PSD movement, if in process is stopped.

• | The rear side door actuator control module sets DTC 13 in memory.

### Conditions for Clearing the DTC

• | The conditions for setting the DTC are no longer present.

• | The power sliding door is re-initialized.

### Diagnostic Aids

• | Inspect for the following conditions:

- | Poor connector terminal contact at the rear side door actuator control module

- | Poor interface of switch plate plungers and striker

- | An open in circuit 1892

- | An open in circuit 750

- | Poor ground, G302

- | A short to ground in circuit 1892

- | A faulty PSD detent switch

• | Prevent bright light from reaching the optical sensor when performing diagnostics with the rear quarter trim panel removed. Bright light may cause the rear side door actuator control module to lose track of the sliding door position.

• | An intermittent failure may be difficult to detect and to accurately diagnose. Faulty electrical connections or wiring causes most intermittent problems. When an intermittent condition is suspected, inspect the suspected circuits for the following conditions:

- | Poor mating of connector halves

- | Backed out terminals

- | Improperly formed or damaged terminals

- | Wire chafing

- | Poor wire-to-terminal connections

- | Dirty or corroded terminals

- | Damaged connector bodies

- | A broken wire inside the insulation

• | Use a J 35616 whenever a diagnostic procedure requests probing or inspecting a terminal. Using the J 35616 ensures that no damage to the terminal will occur. Using the J 35616 provides an estimate of whether the contact tension is sufficient.
