Cause:

Fault in the cable harness or harness-to-harness connectors between the exhaust brake and the valve block or the proportional valve for the exhaust brake.

The exhaust brake is completely closed, which leads to heavy braking of the driving wheel and a risk of skidding.

Influences engine performance, causes misfiring and high fuel consumption.
