These codes were pulled off my PCM today for the ASR OFF light because my ASR doesn't turn on at all. I was wondering what the codes actually mean and what I can do to fix it.

C1215 ABS Inlet Valve Coil RF Circuit Open
C1216 ABS Inlet Valve Coil RF Circuit Short To Battery
C1217 ABS Inlet Valve Coil RF Circuit Short To Ground
C1244 ABS Outlet Valve Coil LR Circuit Short To Battery
C1246 ABS Outlet Valve Coil RR Circuit Failure

Thanks a lot for any help!!!

 

Anybody???

 

They are all to do with the Antilock brakes which you probably figured out by the ABS in every description. Try clearing and see which ones come back. Then diagnose that code or codes. Sounds like the ABS hydraulic unit may have some problems.

 

I cleared them 3 times and they come back instantly. That's why I've been trying to get these codes explained because the descriptions listed don't tell me anything. It sounds like a relay but I don't know where it is or what relay or if that's even the problem?

 

Trying to help ya but it must not be for the vehicle in your sig. Those codes don't exsist for a 98 SS. What are you working on?

 

According to my Chiltons, those are ALL valid ABS diagnostic trouble codes for a 98 F-Body. But the descriptions are different:

C1215 = Electronic Brake Control (EBC) relay contact circuit always active
C1216 = EBC relay coil circuit open
C1217 = EBC relay coil circuit shorted to ground
C1244 = Left front ABS channel will not move
C1246 = Rear ABS channel will not move

Chiltons indicates the EBC realy is in the underhood convenience box.

 

I looked it up in Shopkey5 which is Mitchell and I couldn't find any of them

 

It's a 98 SS...I watched the guy pull the codes with his scanner. I looked at all those relays but didn't know which one it was cause Shopkey didn't say. So you think that one relay could cause all those codes? Thanks a lot!

 

I didn't see a EBC Relay in the boxes under the hood (unless it's in a box I don't know about). Still haven't figured theem out? Still need help!!!

 

I'm still trying to figure these codes out...these descriptions are accurate, that's what comes up when they're scanned and if you clear them they come right back the next time we scanned them. Also the "ABS INOP", "BRAKE", and "ASR OFF" lights are all on and stay on.

C1215 = Electronic Brake Control (EBC) relay contact circuit always active
C1216 = EBC relay coil circuit open
C1217 = EBC relay coil circuit shorted to ground
C1244 = Left front ABS channel will not move
C1246 = Rear ABS channel will not move

Like 96flame said, it has nothing in Shopkey for a 98 SS about these codes which is exactly what's throwing me off. Also, agreeing with 96flame, I believe it has to do with the ABS electronic module under the hood but what can I do to resolve this or at least to determine that it is in fact the module so I don't replace it for no reason. Has ANYONE else had this problem? My mechanic friend said that some Vette owners had this problem and they had to replace the module so I'm hoping that's not my case. ANY HELP WILL BE GREATLY APPRECIATED!!! Thanks a lot!

 

Found this at Autozone. May be worthwhile:

This probably isnt much help but somewhere to start:

1) Random codes. These are also all circuit malfuncions (resistance or voltage is wrong for things such as the ABS solenoids) or the computer/module things they are wrong.

2) Looks like all those codes are internal to the main ABS valvebody or module/computer.

3) For that many codes to pop up at one time means either the sensing circuit/computer/module, supply voltage, or ground wires, any or all combinations are damaged, and not the actual ABS valve body.

Highly unlikely all solenoids or parts of the actual valvebody are bad... I would check wiring first off, then your feeling curious find info that tells you what voltage should be at the solenoids and check for that (no voltage could mean fusable link or something simple). The ABS computer/module is what checks for proper voltage/ground/solenoid resistances so if that goes out then that would explain all these "random" codes. Burnt wires could do the same thing, and in reality could blow out your ABS computer/module.

Are you sure some wires didnt get pinched, melted, or somehow cut? I would check that first.

C1215 ABS Inlet Valve Coil RF Circuit Open (this would be reported with a broken/cut/loose wire or connection on the Right Front ABS Coil - aka solenoid in the main ABS valvebody)
C1216 ABS Inlet Valve Coil RF Circuit Short To Battery (This would be reported with Right Front wire/circuit shorted to 12v)
C1217 ABS Inlet Valve Coil RF Circuit Short To Ground (This is usually when one of the wires are melted/cut/squished to ground)
C1244 ABS Outlet Valve Coil LR Circuit Short To Battery (Left Rear wires are shorted to 12v?
C1246 ABS Outlet Valve Coil RR Circuit Failure Right Rear circuit generally isnt responding or ohms are too high/low (but not completely open

Again, I would suspect in this order:
1) Some wires cut, melted, or otherwise accidentally grounded
2) ABS computer confused, blown, corroded, overheated (aka - damaged). Borrow a friends see if it works or blows his out too.
3) bad ground anywhere in ABS system (same as #1)
4) highly unlikely - any one or all of the coils/aka-solenoids in the ABS valvebody are damaged or reached end of life all at the same time.

I did remove my Traction Control solenoid box (Seperate from ABS) and things were fine for 2 months.. all the sudden the BRAKE light came on... couldnt make it go off. When I finally reconnected the Traction control box the Brake light immediately went off. I never checked the codes but point here is something you may have disconnected or modified months ago could now be throwing a code.

 

Thanks I'll have to look into all those wires. The only thing I've modified, as far as the braking system or TCS goes, is changing the rotors and painting the calipers and I don't see how that would affect it?

 

I see you have headers + y-pipe? Anything could have happened during that install.

Could just be a bad module though.

 

Exhaust has been on since I bought the car 3 or 4 years ago and this occurred within the past year.
