Circuit Description

Code 72 will set if EBCM detects 3 consecutive serial data line messages that are ignored due to errors in transmission. The ANTI-LOCK indicator will NOT be illuminated and system will remain operational when Code 72 is set.

NOTE: Code 72 will only set when an off-board serial data device (Tech 1) is attempting to communicate with EBCM. ALDL flash code and code clearing methods must be used to read and clear code.
