Well on top of what is happening below. Here are some more issues.

1. The dealership thought the problems were being caused by the overhead display. Since last friday it was unplugged and all was well until yesterday.

2. Fueled up the truck and went through the car wash and on the way home the airbag light came on along with a chime.

3. then the headlights would go out

4. Then the tach went to zero.

5. Then everything came back operational.

6. Then it happend again

7. Now the check engine light is on.

This truck is driving me nuts

Here is how it was happening at the beginning. And of course the dealer doesn't know unless he rips the whole truck apart.


1. the turn signals will work intermintantly.
2. air bag light will come on and turn off
3. when i first start the truck the voltage gauge will drop sharply from 14 volts to under 12 then go back, this happens twice and then it seems normal.
4. took to automotive store and they found a code U1403 Fuel Level Signal Received.

I looked a little bit on this website and found it is tied with the PCM? And there may be a short or open circuit. A

Can anyone give me an idea where to look to trouble shoot this or is the PCM taking a poo?

THIS truck is really upsetting me, now i know why the guy traded it off

 

What condition is the battery in?

 

So you went through the carwash, got everything good and wet and then got some electrical issues? Hmmm?

Could it be something got wet?

 

That was the thought at first but why has that been happening all along??? The other times it has happend, the truck was not washed...

Doesnt the TIPM control alot of this?

 

Well i was being more humorous than serious. If you download the service manual for your truck in the links listed below it will go over what all the TIPM covers

 

your turn signals would be a check of oyur multifunction switch, look in the maual for the various voltages and test it.

 

I knew that... I tried to download the book but apparently I dont have the correct software.

The stealership just p/u my truck so lets see what they say.

Thanks

 

Dealer just called and said the bottom of the TIPM is corrdid and pins are missing.

GREAT!!!! That sucks butt!!!!

 

Where do i find it and can i replace it? i suppose it will have to be programmed or flashed? They quoted me 1500 to replace and clean the terminals on the plugs. Is it worth it?

 

finding a replacement isnt an issue but getting them to program it is. PM DirtyDog as he just went through this
