Another AH/TC thread - need your thoughts
Background: had LG longtube headers installed at LG Motorsports back in March; drove the car from Dallas to Ohio with zero problems. Have not driven it much since then and foolishly let the battery run down last week.Second time the battery has gone flat. Put the charger on it, got it back to 12.75 volts (no load) and turned on the key. Immediately got the "Service Active Handling" and "Service ABS" messages.
So, pulled the trouble codes and got:
C1221H - LF wheel speed sensor input is 0
C1222H - RF wheel speed sensor input is 0
C1248H - ??
C1291HC - Open brake lamp switch during decal
C1292 - DTC C1291/C1292 Set Curnt/Prev Ign Cycle??
B2282H - Battery #1 fault DCM left
B2284H - Battery #2 fault DCM left
B2283H - Battery #1 fault DCM right
B2285H - Battery #2 fault DCM right
U1225H - ??
Unless I misread a couple I can't find the ones with no explanation.
My guess is the bad battery has finally caught up with the car, as it exhibited no symptoms of handling or traction control problems prior to its current stay in the garage. Would appreciate any thoughts or suggestions on this; right now my first move seems to be a new battery. Thanks in advance.

C1248 says DRP has been deactivated. Probably due to the fact that two wheel speed sensors on the same axle are having problems.
C1292 Indicates a problem with the brake fluid pressure sensor or the EBCM however it is voltage related.
C1291 has some voltage related items as well.
This could very well be related to your battery problem. Get it sorted out and make sure all battery and ground connections are in good condition and reset the codes and see what happens.

Thanks to everyone who replied. Appears to be solved at this point. Recharged the battery, cleared the codes, started up fine with no codes shown. Promptly took it to get a new battery and had the charging system checked as well - no problems. Just have to drive it more often.
