PROBLEM

Show/hide table

The existing wiring harness can experience noise on the signal lines of the steering cylinder position sensors on certain 793F CMD Off-Highway Trucks and 793F Off-Highway Trucks that have converted to CMD trucks. If the wiring harness noise becomes bad enough it will cause the truck to stop wherever it is.
