The Problem
Bendix has determined that if the trailer-mounted ABS warning lamp circuit experiences an
electrical short for reasons unrelated to the EC-30T, and the short is not repaired, the high side
power switch inside the ECU may eventually become thermally stressed and experience an
electrical short. The high side power switch controls the illumination of the trailer-mounted
ABS warning lamp.

power switch inside the ECU may eventually become thermally stressed and experience an
electrical short. The high side power switch controls the illumination of the trailer-mounted
ABS warning lamp.
If the power switch shorts, it can result in an over-current condition in the ECU and lead to excessive heat, smoke
and in rare cases, even fire in the ECU, the connector or the pigtail wiring harness. The fire that could result from
this situation involves an unreasonable risk to motor vehicle safety. The service, parking and emergency braking
of the trailer and tractor are not affected by this condition.

The Cause
The electrical short must occur in the wiring between the ECU and the warning lamp. Failure cannot be caused
by any wiring defect on the ground side of the warning lamp.
