Antilock Brakes / Traction Control Systems: Service Precautions
Service PrecautionsWARNING: Brake fluid may irritate eyes and skin. In case of contact, take the following actions:
^ Eye contact - rinse thoroughly with water.
^ Skin contact - wash with soap and water.
^ Ingestion - consult a physician immediately.
To help avoid personal injury due to poor braking, DO NOT tap into the vehicle's brake system to operate a trailer brake system.
CAUTION: When fasteners are removed, always reinstall them at the same location from which they were removed. If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may be used. Fasteners that are not reused, and those requiring thread-locking compound will be called out. The correct torque values must be used when installing fasteners that require them. If the above procedures are not followed, parts or system damage could result.
CAUTION: Use only DOT 3 equivalent hydraulic brake fluid. The use of DOT 5 (silicone) brake fluid is not recommended. Reduced brake performance or durability may result.
CAUTION: Avoid spilling brake fluid on any of the vehicle's painted surfaces, wiring, cables, or electrical connectors. Brake fluid will damage paint and electrical connections. If any fluid is spilled on the vehicle, flush the area with water to lessen the damage.
Computer System Service Precautions
Take care to avoid Electronic Brake Control Module (EBCM) circuit overloading. In testing for opens or shorts, do not ground or apply voltage to any circuit unless instructed to do so by the diagnostic procedure. Test circuits only with a high-impedance multimeter. Never remove or apply power to any control module with the ignition switch in the ON position. Always turn the ignition to the OFF position before removing or connecting battery cables, fuses, or connectors.
General Service Precautions
^ Disconnect the EBCM connector before performing any vehicle welding work using an electric arc welder.
^ Do not attempt to disassemble any component designated as nonserviceable. The hydraulic modulator and the EBCM can be separated from each other and replaced separately but cannot be serviced. They have no replaceable parts, and there is no access to the components they contain.
