Thanks for the replies. I finally made the time to investigate further. I was really hoping it was not the fusebox as it would be a more difficult problem to remedy. Since all three of you mentioned an earth issue as a possible cause, that is where I started. The first thing I looked for was the...

My 2004 V8 was parked for a few months while the engine was rebuilt and is now back on the road. The following problem has presented itself: -When driving with the low beams on, the wipers come on when either the high beams are turned on or the horn is honked. -The wipers stay on even if the I...

Since everything was working, I think I will just disconnect it again.

Thanks again for your continued help. I guess I will take a look at header C0287. As my truck is LHD , it looks like this header will be blue, have 20 pins and be located under the glove box near the blower fan. Does that seem right? If I don't see anything wrong with C0287 should the ECU be...

I took on a 12 mile drive and only had it in "D" and no warning light. When I got back home I put it in "R" and the light came on almost immediately. So maybe it is an ECU issue?

Got home from work in time to check this out. The wire does get 12 V when reverse is selected. The wire reads 0V on all transmission selector positions. I'm assuming there should not be 12V on this wire unless there is some kind of probelem? Hopefully this points to a fixable issue.

I will check it tomorrow. I appreciate your continued help!

The only fault was 4023 Gear Information not plausible (other than a few engine misfire codes ;)). The truck does have 4.37 gears. I checked again and the light comes on after putting it in R. Maybe the ECU is bad?

I decided to check the connections on the SLABS after reading about someone having a loose connector. I wasn't having any issues, just decided to check since I already had the kick panel off. All of the three amigos are on during the ignition self test but go off after starting the truck as they...

I am also having a similar problem on my 2004 V8 with an automatic gearbox. I was checking all the connectors on the SLABS module to make sure all were firmly connected while cleaning leaves out of the heater fan. They were but then I noticed a wire with electical tape on the end right by one of...
