CIRCUIT DESCRIPTION
The Power Sliding Door (PSD) is operated through 3 switches installed on the vehicle and via the keyless entry transmitter.

The interior lamp and the multifunction switch located in the overhead console contain the following components:
^ The PSD on/off switch
^ The PSD open/close switch

The PSD on/off switch enables (ON position) or disables (OFF position) the PSD operation. When the PSD on/off switch is set to the ON position, the PSD on/off switch sends a ground signal to the rear side door actuator control module. The ground signal is sent through circuit 1896. This action enables the PSD operation. When the PSD on/off switch is set to the OFF position, circuit 1896 is no longer grounded. This action disables the PSD operation. A ground signal is sent to the rear side door actuator control module through circuit 1894 when either of the following components are pressed:
^ The PSD open/close switch located in the overhead console
^ The PSD open/close switch (RH B-pillar)

This action causes the PSD to either open or close if all of the following conditions exist:
^ The PSD on/off switch is set to the ON position.
^ The sliding door lock is unlocked.
^ The transaxle is in the PARK position (for PSD open commands only).
^ No Diagnostic Trouble Codes (DTCs) are present.

The PSD open/close switch (RH B-pillar) works in the same matter as the PSD switch located in the overhead console.

The following components receive their ground through circuit 650.
^ The PSD on/off switch
^ The PSD open/close switch located in the overhead console
^ The PSD open/close switch (RH B-pillar)

DIAGNOSTIC AIDS
^ Inspect the PSD for the following conditions:
- A faulty PSD on/off switch
- A faulty PSD open/close switch (overhead console)
- A faulty PSD open/close switch (RH B-pillar)
- A short to the ground in circuit 1894
- An open in circuit 1894
- A malfunction in the keyless entry system
^ An Intermittent failure may be very difficult to detect and to diagnose accurately. Faulty electrical connections or wiring causes most Intermittent problems. When an Intermittent condition is suspected, check the suspected circuits for the following conditions:
^ Poor mating of connector halves or backed out terminals
^ Improperly formed or damaged terminals
^ Wire chafing
^ Poor wire to terminal connections
^ Dirty or corroded terminals
^ Damage to connector bodies
^ Wire broken inside the insulation
^ Use a J 35616-A whenever a diagnostic procedure requests probing or inspecting of a terminal. In order to ensure no damage will occur to the terminal use the J 35616-A. This tool will give you an idea of how much terminal tension contact is sufficient.
