DTC 022

Diagnostic Trouble Code Chart:

Wiring Schematic:

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 opened 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.

CONDITIONS FOR SETTING THE DTC
The rear side door actuator control module does not detect the optical sensor pulses during a PSD open or close operation.

ACTION TAKEN WHEN THE DTC SETS
The rear side door actuator control module sets DTC 22 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:
- An open in circuit 340
- Poor connector terminal contact in the PSD electrical connectors
- A faulty rear side door actuator motor assembly
^ 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 be unable to monitor 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-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
The number(s) below refer to the step number(s) on the diagnostic table.
2. This step tests for an open in circuit 340.
3. This step determines if the DTC set due to a poor electrical connection and not because of a faulty rear side door actuator control module.
