Anti-Lock Braking System Electronic Control Unit

The BECM communicates with the ABS ECU via hardwired connections. The BECM receives inputs from the ABS ECU for ETC/ABS warning lamp illumination and message center displays to the instrument pack.

Inputs are also passed from the ABS pressure switch in the form of completed earth paths for ABS warning lamp operation.

The ABS ECU generates a road speed signal which is passed to the BECM. The BECM uses the road speed signal and also passes it to other ECU's to control various vehicle functions. See DESCRIPTION & OPERATION in appropriate ANTI-LOCK BRAKES article.
