ECU help 3 gen

My ECU is in self mode can't get anything to work truck start fine I had code that I didn't fix and the battery die the ECU forgot or is not working will don't get me wrong it is in limp mode the only time the truck power up when I turn key on I don't got no radio nothing but truck start to runs but soon I turn key off inter lights everything goes dead

 

Might need a translator, but @tonered... is this something a tuner can help with?

 

Man this is a tough first post. Sorry Jimmy.

I'd start with whatever code you had that you didn't fix.

 

"My ECU is in safe mode. I can't get anything to work. The truck started fine, I had a code that I didn't fix, and the battery died. The ECU forgot or is not working well. Don't get me wrong; it is in limp mode. The only time the truck powers up is when I turn the key on. I don't have any radio or anything else, but the truck starts to run; but as soon as I turn the key off, the interior lights and everything goes dead."

My interpretation is a code took the truck out of commission, it sat long enough for the battery to die, the ECU somehow forgot it was an ECU because it had no power, and has now defaulted to limp mode.

 

Nicely done. That's what I interpreted as well.

I know some of the tuner folks have been able to unbrick some ECU's that didn't take a tune flash appropriately, so they may be able to help here.

 

Definitely not my expertise, but I'd start with a known good battery, address any and all codes, and spend a day or two with a multimeter/test light. I'm sure if multiple components are out (not getting power), many of them likely all lead back to a common source. I'd probably also lock and unlock my doors with the key fob a few times to ensure the security system isn't kicking in or doing something weird after the power loss.

 

Unfortunately, limp modes typically clear after after cycling the ignition.

The fact that it is running is good. I just have no idea other than a short / rodent damage causing an issue?

Look for any evidence of a nest or chewing on insulators.

 

Wow, slow down and type, I know talk to text is convenient, but it's not getting you any help.

 

does not compute...

but welcome aboard anyways

 

Where did you go to school?

 

I prefer not to share my thoughts.

 

I replaced everything the truck coder read it still saying check Stabilizer I did put new tires on it when I try to reset it I will not could it be in the key fob

 

Steering angle sensor is a pretty common failure after a drained battery. Maybe read some threads about it. Heres one:
