if this is the wrong forum i am sorry
today i went to start my car and the theft deterrent fault popped up on the info center few seconds later the the dash lit up like a christmas tree and guages where going nuts and more fualt messages where going a crossed the info center. air bag, stability, ant-theft
none of the windows will go up or down and the driver door will no longer lock or unlock with the fob or interior button and the driver side mirror will not move passenger will work. interior lights with any door open will randomly turn on and off. the radio will also randomly shut off and on if it is on if you leave it off the radio remains off. head lights will also randomly stop working wile the car is acting up
i checked the codes with my OTC genesis scan tool and this is what it gave me
U1064 Loss of Communications with DIM
U1096 Loss of Communications with IPC
U1255 Serial Data Line Malfunction
U1016 Loss of Communications with PCM
U1040 Loss of Class 2 Communications with ABS
U1160 Loss of Communications with DDM
B1004 Loss of Keep Alive Memory (KAM)
C1288 Steering Sensor Circuit Malfunction
P1599 Engine Stall or Near Stall Detected
i have checked all fuses none are blown even changed the battery as it was originally purchased in 2006. no changes to the car
any ideas would be greatly appreciated as it's my only running car

@ tigger. Is this infamous scotchlock under the seat or PCM issue? Sounds like the latter to me, but could be the former. |

Haha, I throw that POS scotchlok under the bus every chance I get, but it's not the problem here. It only connects the slave door modules to the master Driver's Door Module (DDM). I'd almost bet it's the PCM, but could be the serial data circuit shorting to ground... LOTSA purple wire to chase! mater, You said, "...while the car is acting up". Is this issue intermittent? That would make me lean more towards a short... |

I'd wonder if you had a loose ground to the PCM

yes it's intermittent the only issue that persists is the inability to lock or unlock the driver door. the passenger door has also started to not lock.
the other day the trans dumped down into limp mode for about 5 minutes after that i stopped driving it and it;s parked till i can look at it closer.
if it helps the car has 178,000 original 4.0L and 4l80. had to replace the starter last winter

Well after 2 months and the dealership calling in a gm engineer then shipping the car down to Detroit to gm. Finally found it. It was many things.
First was the driver door modual was shorted internally. But it was not the case as the new one fried after they installed it (at this point it went to Detroit) they then dug through the whole wiring harness and found internally broken wires in the door harness some even poked through there insulation and grounded. This was frying the driver door modual.
It was still messing up but no where near as bad turns out the fuel sender that gas been inoperative sense I bought the car was grounding out and shirting cussing a back feeds to the gauge cluster this was resulting in all the warning lights going off.
Car us back and running great even have a custom made door harness from gm now
