Vehicle Damage Warnings
WARNING^ Certain components in the Antilock Brake System (ABS) are not intended to be serviced individually. Attempting to remove or disconnect certain system components may result in personal injury and/or improper system operation. Only those components with approved removal and installation procedures should be serviced.
^ This vehicle has a Supplemental Inflatable Restraint(SIR) System. Failure to follow the precautions could cause air bag deployment, personal injury, or unnecessary SIR system repairs.
CAUTION:
^ Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. General Motors will call out those fasteners that require replacement after removal. General Motors also will call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and the joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.
^ Before welding on the vehicle with an electric welding unit, turn the ignition switch "OFF" and disconnect the EBCM connectors.
^ Make sure all wiring harness connectors are securely connected.
^ Always note the routing, position, mounting, and location of all components, wiring, connectors, clips, brackets, brake pipes, etc., when servicing the ABS. Speed sensor wiring, routing, and retention is especially important to help prevent false signals due to electrical noise. Proper system operation can only be achieved if the system is restored to its original equipment condition.
^ Do not use a fast charger for starting the engine.
^ Disconnect the negative battery cable when fast charging.
^ Never disconnect the battery from the vehicle electrical system with the engine running.
NOTE:
^ The items mentioned above do not cover every possibility, but must be followed when working on ABS. When doing service work, become familiar with ABS, and how it interrelates with other components on the vehicle.
