General Service Precautions

NOTE: The following notices do not cover every possibility, but are to be followed when working on ABS/TCS. When performing service work, become familiar with ABS/TCS and how it may be interrelated with other components on the vehicle.

The ABS/TCS system is basically maintenance free. When performing work on the ABS/TCS system, the following information must be observed:

If welding work is to be performed with an electric welding unit, turn ignition switch to OFF position and disconnect the EBCM connector.
During painting work, the EBCM may be subjected to a maximum of 85°C (185°F) for approximately two hours.
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. Make sure that all connectors of the wiring harness are securely connected.
Always note the routing, position, mounting, and location of all the components, wiring, connectors, clips, brackets, brake pipes, etc., when performing service on ABS/TCS. Speed sensor wiring routing, and retention is especially important to help prevent false signals due to electrical noise picked up by the wiring.

Proper operation of the system can only be achieved if the system is restored to its original equipment condition.
