Differential Braking Differential braking is automatically activated when drive wheel(s) on one side of the vehicle are spinning. This notifies the vehicle operator that the off-road mode is active. When the ECU is placed in the ATC off-road mode (the lamp will flash steadily every 2.5 seconds). When ATC is no longer active, the ATC active/indicator lamp turns off. During an ATC event (the lamp will flash rapidly at a rate of 2.5/second). Retarder Brake System Control On surfaces with low traction, application of the retarder can lead to high levels of wheel slip at the drive axle wheels, which can adversely affect vehicle stability.ģ. If the ECU does not detect excessive wheel slip, it will not activate ABS control, and the vehicle stops with normal braking. Normal Braking During normal braking, brake pressure is delivered through the ABS PMV and into the brake chamber. Pressure Modulator Valve Chuff Test Bendix® EC‑80™ controllers will perform a Bendix-patented Pressure Modulator Valve (PMV) Chuff Test. Trailer ABS Indicator Lamp Operation Certain models of the ECU will control the Trailer ABS indicator lamp when a PLC signal (SAE J2497) from a trailer ABS ECU is detected. The ECU will illuminate the ATC indicator lamp whenever ATC is disabled due to a Diagnostic Trouble Code. To display blink codes for diagnostic purposes after the external diagnostic switch is activated. When the ECU is placed into the ABS off-road mode (the lamp flashes rapidly). when the vehicle is started) and turns off after the self‑test is completed, providing no Diagnostic Trouble Codes (DTCs) are present on the tractor.

An oscilloscope can be used to measure or identify the presence of a PLC signal on the power line. Identifying a Bendix EC‑80 Controller with PLC Refer to the information panel on the ECU label to see if the controller provides PLC. PLC controller and the Bendix EC‑80 ATC controller (12 volt versions) support PLC communications in accordance with SAE J2497.
