Anti-Lock Brake System (ABS) Fault Lamp Illuminating Immediately After Engine Control Module (ECM) Calibration
Issue
When calibrating an Engine Control Module (ECM) on a unit equipped with a Bendix® EC-80™ electronic controller
the Anti-Lock Brake System (ABS) fault lamp can be illuminated in error immediately after the new ECM calibration
is installed. The ABS fault lamp illumination is caused by an interfacing issue with older versions of the INSITE™
electronic service tool and the Bendix® EC-80™ electronic controller.
The Engine Brake Control parameter by default is set to “enabled” in all standard ECM calibrations. Some Original
Equipment Manufacturers (OEMs) may choose to disable this parameter, which highlights this interface issue. The
Bendix EC-80™controller will recognize the Engine Brake Control parameter as “enabled” before the INSITE™
electronic service tool save and restore function sets the Engine Brake Control parameter to “disabled”. As a result
of the Bendix® EC-80™ controller not receiving the expected Engine Brake Control message over the datalink, the
ABS fault lamp will illuminate.
Verification
ABS fault lamp illuminates immediately after calibrating the ECM on a unit equipped with a Bendix® EC-80™
electronic controller.
