TITLE: Power Door Locks Cycle After Doing S/B 05-005
APPLIES TO: 05 RL
SERVICE TIP:
Just wrapped up doing S/B 05-005, Product Update: Front Door Speakers and Driver's MPCS Unit, and now the power door locks keep cycling?
Here's how to fix this problem:
1. Connect the HDS to the 16P data link connector (DLC), and check for B-CAN DTCs. If you find any, clear them. If any of them come back, do the appropriate troubleshooting procedures before continuing.
2. Make sure the ignition switch is turned to ON (II). From the rear seat, push and hold the rear power window switch to lower the rear power window all the way. Pull the switch up, and hold it to raise the window all the way. Do this for the other rear power window.
3. Test-drive the vehicle for 15 to 30 minutes. Make sure the power door locks work properly.
- If the power door locks work properly, return the vehicle to your client.
- If the power door locks keep cycling, you need to do a battery cable reset. Go to step 4.
4. Make sure you have the anti-theft codes for the radio and the navigation system, then write down your client's audio presets. Make sure the ignition switch is turned to LOCK (0).
5. Disconnect the negative cable from the battery first, then disconnect the positive cable.
6. Turn the ignition switch to ON (II), and hold the positive cable to the negative cable for 1 minute. Turn the ignition switch to LOCK (0).
7. Reconnect the positive cable to the battery first, then reconnect the negative cable.
8. Test-drive the vehicle. Make sure the power door locks work properly.
- If the power door locks work properly, go to step 9.
- If the power door lock still keep cycling, then press on with normal troubleshooting.
9. If necessary, enter the anti-theft codes for the radio and the navigation system, then enter your client's audio presets.
10. Do the power window control unit reset procedure.
11. Do the steering column position memorization procedure.
The battery cable reset may clear all stored memory settings. Make sure you let your client know he or she will need to link the keyless remotes and to restore all of the DPMS custom memory settings.
