DIC Codes - can anyone tell me what these mean ?
Can anyone tell me what these codes mean and what could of gone wrong:
10 PCM
P0101 H - Mass air flow system performance ?
BO-RFA
U1096 H - Loss of Communication with IPC
U1016 H - Loss of Communication with PCM
U1064 H - Loss of Communication with BCM
C2120 H C - TPM System Malfunction (No Sensors Received)
58 SDM
B1001 H
car is idling really rough, noticeably louder, car shakes at idle, rev limiter surges while idling, wanting to shut off, can hardly accelerate, bogs when i want to accelerate and can smell heavy fumes out of the exhaust(gas like). No smoke though.
thanks

The H shows they are all history codes may have been a previous problem. The c code is the one to look at. Try clearing codes to get an accurate description of the problem :banghead:

would you or anyone else know what might trigger these particualr codes?
10 PCM

C2120 H C - TPM System Malfunction (No Sensors Received)

All of your codes indicate problems with the Tire Pressure Monitoring System.
None of them explain the rough running.
I would clear all codes and see if that clears things up
You need a trip to the dealer to deal with the TPM stuff..

Re: DIC Codes - can anyone tell me what these mean ? (nevrenuf)
i think u might be right Tom, about the sensors.. totally forgot about that.
i dont have sensors on my wheels, being that i bought a used set of ZO6 rims and tires.
the one code that I am wondering about is the B1001 code...
and those fumes are nasty... heavy fuel like fumes, as if my O2 sensors were screwed and car is running really rich or something.... and cant accelerate....bogs too.

Re: DIC Codes - can anyone tell me what these mean ? (johnnyC5)
Can anyone tell me what these codes mean and what could of gone wrong:
10 PCM
P0101 H - Mass air flow system performance ? Can be caused by poor connections, starting the vehicle without the MAF connected, broken wires, worn wires, intermittents caused by a worn wire; entrance of unmetered air into the intake due to a vacuum leak, leaking PCV system, even the engine oil dipstick not seated properly. When the PCM sets this code it goes into a speed density (RPM, MAP, IAT) for fuel management algorithm. If it is History, don't worry unless it comes back again.
BO-RFA
U1096 H - Loss of Communication with IPC
U1016 H - Loss of Communication with PCM
U1064 H - Loss of Communication with BCM A state of health signal is sent out via the data links communication circuit, at one time it did not have communciations with the IPC, PCM and/or BCM. So it set the codes. Again, don't worry unless they return again.
C2120 H C - TPM System Malfunction (No Sensors Received) Easy, your BCM is looking for tire sensors that no longer exist. If you no longer have your tire sensors, I believe a GM dealer, or someone with a Tech 2, can flip a chip in the BCM to stop looking for the pressure sensors.
58 SDM
B1001 H Restraints (air bag) ID codes did not match at one time between the SDM (sensing and diagnostic module...also known on the Corvette Forum as the infamous "black box") and the BCM. Did you ever have the BCM replaced or reprogrammed or the SDM replaced or reprogrammed. If so, and the tech did not erase the code, that could be the problem. Again, if it is History, don't worry unless it returns. Evidently, there is no problem with the air bag system, since if there were, the Air Bag light would be illuminated.
car is idling really rough, noticeably louder, car shakes at idle, rev limiter surges while idling, wanting to shut off, can hardly accelerate, bogs when i want to accelerate and can smell heavy fumes out of the exhaust(gas like). No smoke though. How are your ignition wires? If original, spray them down with some water at night and see if you have a spark show under the hood. If not the wires (or plugs), it sounds like fuel. Could be a plugged filter, but these are extremely rare in these days. Could be a bad injector(s). Could even be a bad generator. Hard to diagnose without attaching some pressure gages, or inspecting the wires/plugs/coils/charging system. The codes you listed don't reflect these idle/surging conditions you say the car has. Sounds like you need a trip to a GOOD dealer (if there is one) or a good tuner shop.
thanks

Re: DIC Codes - can anyone tell me what these mean ? (johnnyC5)
As far as the C2120 TPM code goes, not even a Tech2 can eliminate that code as your car is a '99. If it was a 2001 or newer than the TPM sytem could be turned off as some C5's had sensors and some (ZO6) did not. In '99 all C5's had sensors so it is not an 'option' as far as the Tech2 is concerned.
I learned this the hard way by unsucessfully trying to turn off the sensors on a '97 with my Tech2.

Re: DIC Codes - can anyone tell me what these mean ? (WhiteC5Vette)
great feedback everyone, much appreciated....
reset the codes, still getting that P0101 H code...
noticed one thing though.... there is a plug (female) attached to the Fan Shroud, near the bottom, on the passenger side... and it is unplugged, and one of the pins is gone from the corrosion. i put my hand down there, between the fan shroud and inside part of the bumper, and fished out another coonector (Male end). These seem to go together...
what is this plug for?

That sounds like the outside temp sensor, what is it showing on your A/C control module for outside temp :cheers:

Re: DIC Codes - can anyone tell me what these mean ? (runamuk)
i thought it was for the the fog light option... or some kinda option i which i dont have.
i have the manual controls for my HVAC controls... i dont have the LED dual climate contro setup... 99 FRC.
