Circuit Description
The rear side door actuator control module uses a vehicle speed signal input. While the vehicle is in motion, the powertrain control module (PCM) cycles the voltage in circuit 389 between low and high 4000 times per mile. The rear side door actuator control module uses this input in order to determine when the vehicle is in motion.
The operator may command the power sliding door (PSD) to close while the vehicle is in motion. Inertial force acting on the sliding door caused by the vehicle's motion, may reverse the sliding door. The rear side door actuator control module recognizes that the vehicle's motion may have caused the reversal and will continue to close the sliding door.
Conditions for Setting the DTC
The rear side door actuator control module has not detected a high signal on circuit 389 for 5 consecutive ignition cycles.
Action Taken When the DTC Sets
| • | The rear side door actuator control module inhibits opening the PSD if the ignition switch is on. |
| • | The rear side door actuator control module permits opening the PSD if the ignition switch is off. |
Conditions for Clearing the DTC
This DTC clears if all of the following conditions are met during the next ignition cycle:
| • | When exiting the diagnostic mode |
| • | If the rear side door actuator control module detects activity in circuit 389 (VSS circuit) for 10 seconds. |
| • | If the rear side door actuator control module detects activity in circuit 389 (VSS circuit), and detects low voltage in circuit 275 (the transaxle in PARK input). |
Diagnostic Aids
| • | Inspect the system for the following conditions: |
| - | A short to ground in circuit 389 |
| - | An open in circuit 275 |
| - | A malfunction in the transaxle range switch circuitry |
| - | A faulty control module rear side door actuator |
| • | An intermittent malfunction can be very difficult to diagnose accurately. Faulty electrical connections or wiring cause the most intermittent conditions. |
| If you suspect an intermittent condition, inspect the suspect circuits for the following conditions: |
| - | Wire chafing |
| - | Damaged connector bodies |
| • | Use a J 35616-A whenever a diagnostic procedure requires probing or testing a terminal. Use this tool in order to avoid damaging the terminal. Using this tool will help determine if the terminal tension is sufficient. |
Test Description
The number(s) below refer to the step number(s) on the diagnostic table.
-
This step verifies the integrity of the vehicle speed signal.
-
This step determines whether the malfunction is intermittent, or the rear side door actuator control module is faulty.
Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Was the Power Sliding Door (PSD) Diagnostic System Check performed? | -- | Go to Step 2 | |
2 | Does the speedometer operate correctly? | -- | Go to Step 4 | Go to Step 3 |
3 | Refer to Speedometer and/or Odometer Inaccurate in Instrument Panel, Gauges and Console for further diagnosis of the vehicle speed signal. Is the action complete? | -- | Go to Step 7 | -- |
4 |
Does DTC 32 reset? | -- | Go to Step 5 | Go to Step 6 |
5 | Replace the rear side door actuator control module. Refer to Rear Side Door Actuator Control Module Replacement . Is the repair complete? | -- | Go to Step 7 | -- |
6 | Malfunction is intermittent and not present at this time. Contact the Technical Assistance Center for the latest technical information and troubleshooting hints. Is the action complete? | -- | Go to Step 7 | -- |
7 |
Does the power sliding door operate properly? | -- | System OK |
