Drove over a brake drum (dark street, around a corner - didn't see it but I was only going 10 mph). Went into reduced power, because the wires into the PCM were ripped out. Here's the damage they repaired...

Replace Right Fender & Paint
Replace Right Lower Inner Panel
Replace Right Lower Filler Panel
Front Bumper R&R, Repaint
Replace Emblem
Replace Right Valence
R&R Mirror, handle, blend paint
Blend paint door, hood, headlight
Replace PCM Inner Bracket
Replace PCM Outer Bracket
R&I PCM
Replace Module Actuator Throttle Control
Replace Engine Harness Connector
Replace I/P Harness Connector
Replace Tire
Wheel Alignment
RF Wheel Repair

Picked it up, and it went into reduced power mode again on the way home; service ABS, traction, etc... It's been back to the dealer two times with no luck getting the codes to not come back. Picked it up a week ago, after they replaced the accelerator pedal assembly, and no codes till last night. Doing 70 down the freeway, just cruising, it went into Reduced Power mode again, service ABS, etc - the usual.

When I pulled over, codes were:

P1125 APP System -A (History & Current)
P1275 APP Sensor 1 Circuit-C (H&C)
P1276 APP Sensor 1 Circuit Performance –C (H&C)
C1278 TCS Temporarily Inhibited by PCM (most likely tripped by other codes) (H&C)

I turn the engine off, turn ignition on, reset codes, and everything is great.... until the next time.

Anyone have any ideas or thoughts as to what could be causing this? I don't want to leave it at the dealer for another week to have them "play" with it...

TIA, Steve

 

I wonder about damage to the BCM.
It is located in the right side footwell, the area where the damage was done.
You have PCM codes, but that was replaced, so I'm wondering about the BCM.
I hit a heavy bump in the road and thats when I started having problems with my BCM and I tripped TCS codes.
Now replaced and all is fine.

So they replaced the BCM entirely? Do you know how I access the BCM? The damage was a hole behind the front wheel, and the ECM was ripped off the brackets. I did notice this morning a noise, like something was loose, coming from that area when I turned a corner, but I put it down to the manual in the glove box.

Thank for you input!
