Warning:
Unless directed otherwise, the ignition and start
switch must be in the OFF or LOCK position, and all electrical
loads must be OFF before servicing any electrical component.
Disconnect the negative battery cable to prevent an electrical
spark should a tool or equipment come in contact with an exposed
electrical terminal. Failure to follow these precautions may result
in personal injury and/or damage to the vehicle or its
components. For Vehicles equipped with
OnStar® (UE1) with Back Up Battery: The Back Up Battery is a redundant power supply to allow
limited OnStar® functionality in the event of a main vehicle
battery power disruption to the VCIM (OnStar®module). Do not
disconnect the main vehicle battery or remove the OnStar® fuse
with the ignition key in any position other than OFF. Retained
accessory power (RAP) should be allowed to time out or be disabled
(simply opening the driver door should disable RAP) before
disconnecting power. Disconnecting power to the OnStar® module
in any way while the ignition is On or with RAP activated may cause
activation of the OnStar® Back-Up Battery (BUB) system and will
discharge and permanently damage the back-up battery. Once the
Back-Up Battery is activated it will stay on until it has
completely discharged. The BUB is not rechargeable and once
activated the BUB must be replaced. |
