ABS Component Replacement and Electrical Warnings

Observe the following general precautions during any ABS/TCS/ICCS service. Failure to adhere to these precautions may result in ABS/TCS/ICCS system damage.
1. Unplug the Electronic Brake and Traction Control Module (EBTCM) harness connector before performing electric welding procedures.
2. Carefully note the routing of the ABS/TCS/ICCS wiring and wiring components during removal. The ABS/TCS/ICCS components are extremely sensitive to EMI (electromagnetic interference). Proper mounting is critical during component service.
3. Do not use a quick charger for engine starting or for battery charging with the battery still connected. Brake failure or ABS/TCS component damage may result.
4. Disconnect the battery with the ignition OFF.
5. Disconnect the EBTCM connector with the ignition OFF.
6. Do not attempt to repair the Brake Pressure Modulator Valve (BPMV) or any other non serviceable ABS/TCS/ICCS components where noted. Many ABS/TCS/ICCS components are serviceable by component replacement only.
7. Do not hang the suspension components from the Wheel Speed Sensor (WSS) cables. The cables may be damaged.
8. Do not subject the EBTCM to temperatures of more than 85°C (184°F).
9. Do not use petroleum based fluids in the master cylinder. Do not use any containers previously used for petroleum based fluids. Petroleum causes swelling and distortion of the rubber components in the hydraulic brake system, resulting in water entering the system and lowering the fluid boiling point.
10. Inspect the ABS/TCS/ICCS system after service using a scan tool.
