Circuit Description
The Power Sliding Door (PSD) operates through three switches installed on the vehicle, and via the keyless entry transmitter.
When the B-pillar PSD open/close switch is pressed, the PSD open/close switch sends a ground signal to the rear side door actuator control module through circuit 1894. This action causes the PSD to either open or close (depending on the position of the door) as long as the power sliding door is unlocked, the transaxle is in PARK (for open command only), and no Diagnostic Trouble Codes (DTCs) are present.
Diagnostic Aids
| • | Inspect for the following conditions: |
| - | A faulty RH B-pillar PSD open/close switch with the internal contacts always open |
| - | An open in circuit 1894 |
| - | An open in circuit 650 |
| • | 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. |
