The truck started running a little funny on monday. I was running the canned performance tune from the SCT x4. I never had a problem with that tune. I got the truck home, not running horribly, check engine light never came on. Somewhere between trying to revert back to the stock tune, i got a com error on the sct x4. The errors on the sct were 21301, and also 110D8. I looked those up, and I've been trying to contact SCT to get this straightened out. Apparently The stock tune got lost , or something, according to those error codes. I've been trying to contact SCT for 2 days now and apparently the tech must be on vacation or something because I've yet to reach a tech. I keep getting a message to please call back later. Total BS!
The starter is good, I jumped it to the yellow wire on the passenger side fender...it turns over.
So in the mean time I tried to pull codes off the truck and I did get some.
B1201 Body,is a fuel sender error. The fuel guage had been acting up for about a week. No biggie.
B1352.Body. is a Ignition key in circuit failure...interesting. But it seems to be ok unless something got screwed up when i shut it off for the last time.
B2900 Body. Sets when there is a VIN mismatch between the module with the B2900 and the Powertrain Control Module (PCM). Either the PCM or the body module stored VIN may be incorrect. Read more: https://www.autocodes.com/b2900_ford.html
U0101, TCM com loss...ok now we're getting somewhere, maybe.
U1900 CAN com loss. has to do with guage cluster coms and ABS?, 4wd? I think.
u2023 fault received from external node. This seems to refer to a com loss between the ECU and some other control unit. Might be the TCM or one of the other controllers.
Thats all I got.I checked for loose plugs and chafed wiring, so far no joy.
I checked the starter relay and fuses, and Ignition relay and fuses. But I need to investigate those a little further, I ran out of time.
I got off early today to try and contact SCT during normal business hours, did I mention that they never ever answer the effing phone.
The truck ran and started, though not the greaest until I tried to load the stock tune back on it. Then Maybe the battery ran down and corrupted the download. Thats all I can think of.
I just dissconnected the batteries, to maybe hopefully reset the ECU. I'm grasping at straws here.Help!
