The ABS system has switched off and the antilock function is NOT operating. The brakes continue to operate with ABS ECU fault (or ECU removed) but remember the ABS function is not operating and wheel lock-ups can occur with heavy brake applications, especially on wet or icy roads.
1) Check ECU identification number. Affected ECUs are ATE Controllers part numbers 10.0943-0202.4 / 10.0943-0203.4 / others / on printed WHITE label. Click here to see photo of offending ECU for positive identification as there are many conflicting numbers on ECUs!
2) Confirm ABS light remains on after starting engine. An ABS light that goes out then comes on WHILST driving away indicates ABS sensor problem.
