Technician Safety Information

Certain components of the ABS system 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 the components with removal and installation procedures should be serviced.

Use the following general precautions whenever servicing the ABS system:
a. If any welding work is to be performed using an arc welder, CAB should be disconnected.
b. When the ignition switch is in the ON position, the CAB electrical connector should not be disconnected or connected.
c. Some components of the ABS system are not serviced separately and must be serviced as complete assemblies. Do not disassemble any component which is designated as non-serviceable.
d. Always de-pressurize the hydraulic accumulator, refer to Brakes and Traction Control/Brakes/Antilock Brake System/Accumulator/Service and Repair when performing any service that requires disconnecting any hydraulic tube, hose or fitting. The ABS system uses brake fluid at high pressure. Failure to de-pressurize the accumulator may result in personal injury or damage to painted surfaces.
