Icon1 Help 2acc and 2acb and 3100 codes! - 01-05-2016, 02:09 AM

Was on the way home from a drag race and was driving 20kmh and all of a sudden all warnings were up and car starts to act funny, rpm up and down. Cleared the codes and got 2acc and 3100 code. Then i had to tow the car to a workshop nearby. So the next day the mechanic changed the lpfp. Now rpm is normal but throttle not working. And current code now is 2acc and 2acb and 3100. Please help me. Mods are per signature. Thanks!

2ABC is the TMAP in the CP. 3100 is a result of that.

whoops, a bit of lexiadys there.


2ACB DME digital motor electronics main relay, input signal
2ACC DME digital motor electronics main relay, switch delay

I'd image both of those would put you in to limp mode (3100)

I'm not sure what the issue is. I'd have your mechanic look in to it.

Mosfets usually throw a 30BB code.

Fuses blow for a reason, you need to track down the root of the issue.

We won't be able to tell you. Best to have your Indy investigate and diagnose the issue.

Hey, Ive got the same codes on my DME - 2ACC and 2ACB and the Car will not turn over. Not sure the DME would cause this but appears the DME also needs work. Can you describe how you fixed this? my car is a build date 11/06, DME number is 07611397
A little background, the lead to my water pump rubbed against the exhaust manifold and melted frying parts of the wiring harness, several sensors and the water pump. I've replaced the wiring harness, CAM sensors and Vanos solenoids. Also new water pump and thermostat. I open the door and the red steering wheel lock illuminates and the steering wheel is locked. Inserting the key does nothing to unlock the steering wheel. All other electronics seem fine but the steering will not unlock and the car will not start. Any ideas?

Do u think fry jb4 will cause this also? I on n20 tmap. If i took jb4 out it will have problems. and i have chucked the stock tmap away .. (I know i'm not supposed to do that )
And i have put jb4 out in the first place but that time we din't know that the relay was not working. So we put back jb4 and figured that the dme 30a fuse was blown. So we took a dme relay from someones car and replaced with mine then hit on start, the car starts fine and idle perfectly normal. So we left itfor 30mins, and still fine. So we started to drove the car and like after 1km, car died again. And the 30a fuse blown again. And i'm sure the dme relay is also blown. So i just ordered the dme relay which is quite costy here in Malaysia rm110. And i took out the ecu and gave it to a friend of mine whos experienced with blown dme. So he checked and dme is fine, not blown. So now i'm stuck with what to do. Been 2weeks now
