Indicator Failure
- If tests of warning light does not prove out, connect Breakout Box to ABCM with adapter cable. Connect Breakout Box pin No. 1 (if testing ABS warning light) or pin No. 4 (if testing Red brake warning light) to ground pin.
- Turn ignition switch to ON position. Wiggle wire harness at several point between ABCM and instrument cluster. If warning light flickers, repair or replace respective wiring circuit.
