4xrockrod@gmail.com Report post Posted September 26, 2020 I have a check engine light on my beaver motorhome. i read the CAT manual says you can do self diagnostic on it by leaving the cruise control switch off have key on and push and hold the set/resume switch. i did this and tried 5 times and nothing. the coach has been setting in storage i just got it running and want to drive it home about 170 miles but not sure about this engine light. thanks Share this post Link to post Share on other sites
