Vehicle Damage Warnings

ELECTRICAL AND ELECTRONIC COMPONENT DAMAGE
- Never disconnect the battery from the electrical system with the engine running.
- Never connect or detach the Electronic Brake Control Module (EBCM) harness connector with the ignition switch ON.
- Before performing electric welding procedures, unplug the EBCM harness connector.
- Do not use a fast charger for engine starting. Disconnect the battery from the vehicle electrical system when fast charging the battery.
- Do not hang the suspension components by the wheel speed sensor cables; these cables are delicate.
- Take extreme care not to damage the toothed exciter ring. Also, do not hammer the tooth ring. Striking this can cause demagnetization or polarization, affecting the accuracy of the speed signal returning to the ABS control module.
- When servicing or replacing ABS components including the EBCM, wheel sensors, hydraulic valve, or wiring harness, verify proper ABS operation using approved procedures.
- Always carefully note the routing, position, mounting and location of ABS wiring, connectors, clips, brackets, etc. Anti-lock components are extremely sensitive to EMI. Proper mounting is critical when servicing ABS components.

WHEN PAINTING: the following temperature limitations apply:
- Do not expose the EBCM to temperatures above 95~C (203~F) except for brief periods.
- Do not expose the EBCM to temperatures above 85~C (185~F) for longer than two hours.

BRAKE FLUID CAUTIONS
- Use care when handling brake fluid to avoid paint or plastic component damage.
- Never use DOT 5 silicone brake fluids in the ABS system; silicone brake fluid will seriously damage ABS hydraulic components.
- When adding fluid to the anti-lock brake system, use only DOT 3 brake fluid from a clean, sealed container. Brake fluids meeting DOT 3 specifications are glycol-based. Glycol-type brake fluids are NOT compatible with silicone-based fluids.
- Do not use brake fluid from any container which is wet with water. The use of improper brake fluid, water contaminated, or mineral oil contaminated brake fluid will cause deterioration of rubber ABS components.

BRAKE LINE ROUTING
- Make absolutely sure the brake lines are properly routed after service.

COAT THE WHEEL SPEED SENSOR WITH AN ANTICORROSION COMPOUND
- Coat the wheel speed sensor with an anticorrosion compound before installation. Do not use grease.
