WARNING

Anti-lock Braking System (ABS) is an electrical system. When working on ABS the same

precautions must be taken as with any electrical system. The danger of electrical shock or

sparks exists which could ignite flammable substances. ALWAYS disconnect the power to

the system before any repairs are made. Failure to comply may result in death or injury to

personnel. Seek medical attention in the event of an injury.

CAUTION

When welding on an ABS equipped vehicle or semitrailer, disconnect the power connector

from the Electronic Control Unit (ECU). Also disconnect the power from the ECU/Valve

Assembly before removing any components. Failure to follow this caution can cause faults

to be recorded and stored in the ECU memory. Failure to comply may result in damage to,

or destruction of, equipment or mission.
