Popular Post theakerstwo Posted February 4, 2023 Popular Post Share Posted February 4, 2023 I had a RW that was doing same thing.I used some steel wool on the sensor and that stopped that.I dont know if it was the cleaning or if it was a bad connection on the sensor plug/in. 1 2 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/72469-cl-engine-shutdown-light-and/#findComment-524576 Share on other sites More sharing options...
Dirtymilkman Posted February 7, 2023 Share Posted February 7, 2023 When you first start it up are the cab air bags deflated? Where the harness comes through the firewall for the shutdown system it can rub through. When your cab is down it pulls harder on the wires, same as with hitting bumps. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72469-cl-engine-shutdown-light-and/#findComment-524779 Share on other sites More sharing options...
