Code B0-RFA C2120 ???? 99 C5 Diagnostic
Going through my codes I discovered a code that I could not identify on Corvette Doc. I hope I did not look right at it and missed. But has anyone seen this code before?? Will you please help me out?
Thank you very much

doesn't look like a trouble code, you missed something. But I will look later to make sure something seems like I have seen it before.

Thanks alot this explains the tire pressure warnings. Shouldnt the active handling have a code as well if the warning is always being displayed? The check engine light and warning is on as well would it be shown under the codes somwhere as well?? I had a total of 7 codes 3 for air bags 3 for the air conditioning and now the 1 for the tire sensors. Would these other 6 make the engine light come on?

2120 indicates the receiver has lost the signal from the sensor(s).
It could be a potential problem or just a glitch.
You should clear the code and reprogram the sensors and see if it comes back.
Here's the link to program the sensors:

Active Handling has nothing whatsoever to do with the tire pressure system.
The check engine light is displayed whenever an emissions-related trouble code is set....these will almost always be in the 10-PCM section.
List all your codes and we can probably figure what tripped the CE light.

The codes that showed current were B0017/B0026/B0051. Air bag codes
P0645/P0480/P1546. Air Conditioning Codes
And the B0-RFA C2120 Tire sensor codes.
Would any of these cause the service engine light????

This what I found
B0-RFA - Remote Function Actuation
C2120 TPM System Malfunction (No Sensors Received)
If all those codes coming up sounds like you are having a control module going bad on you that feeds all these circuits, if there all on the same Body control module. And as I was looking today there's like about 9 body control modules on the vettes, plus your PCM.

those sensor's on the wheels an't like your ABS stuff now. I can't believe how many problems people are dealing with on these Corvette's. Okay I can, I guess thats why GM is going under.

there is only 1 bcm.there is a tac,pcm,rfa,ebcm,sdm,ldcm,rdcm,hvac[dual zone],rtd. the tpm faults are because i think he swapped over wheels. the 2 a/c faults are for system performance and a compressor clutch circuit[may be out of refridgerant or a default because there is a cooling fan problem].
the faults are NOT a bad control module[highly unlikely].the tpm system is built into the rfa module.the airbag module[sdm]is a stand alone unit,the pcm is another.more than likely his glitches are all minor problems. has nothing to do with GM's profit problems.that is a whole other ball game. on low speed the fans run in a series circuit[one fan gets its ground by going through the other]and on high speed they switch over to a parrallel circuit.that's why there are 3 fan relays.if the fans go straight to high without seeing low first,the pcm knows something is wrong[this was basically a short cooling fan lesson].
the airbag faults are because the car has been in a wreck or THINKS it's been in a wreck[51 is deployment commanded.the other 2 are for the front airbag deployment circuits first stage.gm uses 2 stages depending on speed,impact,rate of decel,etc.].this one may be a bad sdm if the car hasn't been wrecked.if the bags haven't gone off,the unit is bad[this is common].but with the front bag faults,the car has probably been in a accident.JMO
