Power Sliding Door - Alarm Always On

Diagnostic Chart:

Schematic:

CIRCUIT DESCRIPTION
The rear side door actuator control module monitors the position of the transaxle shifter through the transaxle range switch. If the transaxle is shifted out of the PARK position while the PSD is open, the rear side door actuator control module sounds the power sliding door alarm to warn the driver that the door is not fully closed.

If the transaxle shifter is out of PARK and the operator commands the PSD to open, the rear side door actuator control module sounds the power sliding door alarm (for as long as the PSD open/close switch is pressed) to warn the driver that the power sliding door has been inhibited from opening.

In addition, during PSD diagnosis, the power sliding door alarm is also used to read Diagnostic Trouble Codes (DTCs) stored in the rear side door actuator control module.

When the transaxle is in the PARK position, the transaxle range switch sends a B+ signal to the rear side door actuator control module through circuit 275. When the transaxle is shifted out of the PARK position, the transaxle range switch removes the B+ signal to the rear side door actuator control module.

The rear side door actuator control module energizes the power sliding door alarm (causing the power sliding door alarm to sound) by sending a B+ through circuit 902. The power sliding door alarm is grounded through circuit 901.

DIAGNOSTIC AIDS
^ inspect for a short to B+ in circuit 902.
^ 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:
- Improperly formed or damaged terminals
- Wire chafing
- Damaged connector bodies
^ Use a J 35616-A whenever a diagnostic procedure requests probing or inspecting a terminal. Using the J 35616-A ensures that no damage to the terminal will occur. Using the J 35616-A provides an estimate of whether the contact tension is sufficient.

TEST DESCRIPTION
