I have not been able to use the cruise control because each time I engage it, the check engine light appears. I had the service center check it and they found no problem. Anyone have any ideas what may be happening?
I have a 2006 Beaver Monterey Laguna IV with 400 hp cat C9
Thanks

I presume your exhaust brake switch is set to off when you try to use the cruise?

From your description, it sounds like your Smart Wheel control module is malfunctioning, however it will usually cause erratic problems with your windshield wipers also when the module fails, but not always.

If it malfunctions, the Smart Wheel control module can light the check engine light when a function is requested without setting a trouble code in the ECM (engine control module).

We had this problem. It was caused by dirty contacts in the steering wheel.

You can get contact cleaner at any Radio Shack store in an aerosal can.

You can not access the steering wheel control contacts without removing the steering wheel. So randomly spraying a contact cleaner into the steering wheel area will probably do more damage than good.
