### 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 CKT 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 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.

### Test Description

The number(s) below refer to the step number(s) on the diagnostic table.

1. This step tests for an open in CKT 340.

2. This step determines if the DTC set due to a poor electrical connection and NOT due to a faulty rear side door actuator control module.

Step | Action | Value(s) | Yes | No
--- | --- | --- | --- | ---
1 | Was the Power Sliding Door (PSD) Diagnostic System Check performed? | -- | Go to Step 2 | Go to Power Sliding Door (PSD) Diagnostic System Check
2 | Using a J 39200 digital multimeter (DMM), measure the voltage by backprobing between the rear side door actuator control module harness connector C1 terminal C and ground. Is the voltage within the specified range? | B+ (10-14 V) | Go to Step 3 | Go to Step 4
3 |

1. Perform the PSD re-initialization procedure. Refer to Power Sliding Door (PSD) Re-Initialization .
2. Enter the Diagnostic Mode 1: Reading DTCs. Refer to Diagnostic Modes in Power Sliding Door (PSD) Diagnostic Information .

Does the DTC 22 reset?

Go to Step 5

Go to Step 6

4 | Repair the poor connection or the open in CKT 340. Refer to Wiring Repairs in Wiring. Is the repair complete? | -- | Go to Step 7 | --
5 | Inspect the rear side door actuator control module connector C1 and connector C5 for poor terminal contact. If the connectors are OK, replace the rear side door actuator motor. Refer to Power Sliding Door Motor Clutch Replacement . Is the repair complete? | -- | Go to Step 7 | --
6 | A malfunction is not present at this time. Refer to Diagnostic Aids for additional information. Is the action complete? | -- | Go to Step 7 | --
7 |

1. Turn the ignition switch to the LOCK position.
2. Reconnect any connectors/components removed.
3. Perform the PSD re-initialization. Refer to Power Sliding Door (PSD) Re-Initialization .

Does the PSD operate correctly?

--

System OK
