Convertible Top Does Not Function after Battery Replacement - kw 4.6 accessory battery body charge dead door DTC electrical entry information inoperative LH2 lock module operation performance power

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Thursday, October 16, 2003 This is a service VME to all Cadillac dealers regarding the XLR and battery disconnects. Anytime the battery is disconnected or if the battery is in a rundown condition and requires a charge such as in an extended storage period, the windows need to be initialized in order for the top to operate properly. The top will not operate and the windows express up and down will not function unless the window module knows the window position. This will occur anytime power is lost to the window module; for example, when the battery is disconnected. To initialize the windows both doors must be fully closed, then push the window switches to the up position and hold for five seconds. Once the window module learns the window’s position the top will operate properly. If the door window express up or express down function does not operate, use the window initialization process before attempting any repairs.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.
