Ecm

[MOliveira]

I have a 2009 stock truck. I installed a CM flatbed on it the first week I got the truck. After about two years the lights on the flat bed and my parking lights started doing some strange things. I was informed the ECM was bad and I had to replace it. That was about six months ago. Yesterday while fueling up the truck reved up and then died, and I mean DOA. Towed it to the place that replaced the ECM and said they have recently had to replace ECM's on about a half dozen other trucks in the last year, all had flat beds installed. Has anyone heard of this problem?

The ECM doesn't have anything to do with lighting, that's all TIPM related.

You're right my mistake

you should really look at the "TIPM" saver.

If he's not making those units, look at the pic and replicate one.

I now have all headache, rear bumper and trailer light on a separate auto-reset fuses and on relays.

I now never have to worry about frying the tipm due to added electrical devices, or bad trailer wiring.
Thanks to his, now, plug and play unit.

The problems have nothing to do with CM flatbeds or any flatbeds but with sloppy or faulty wiring harnesses or workmanship by whoever installed the beds.

I bought my truck in January '08 and had a CM bed installed a couple days after I bought it. I've never had a light problem, a TIPM problem, or any problem with the truck other than a failed U joint at 75k miles a couple years ago.
