PROBLEM

Show/hide table

The engine harness needs to be inspected and possibly replaced on certain C3.4B Industrial Engines installed in TL943C and TL642C Telehandlers. The existing engine harness does not have a section of the harness crankshaft sensor wiring shielded which may therefore introduce spurious signals to the engine ECM.
