Ironman433

As many have advised to do, I read all of the DTC Codes in manual mode and these are the ones that came up. I have never cleared the codes in the year that I've owned the car. There was only one listed as current:

BCM:
B0433 H: Rear Defogger Relay Circuit
B2528 H: Horn Relay Circuit
B2578 H: Right Front Turn Signal Monitor Circuit
B2583 H: Left Front Turn Signal Monitor Circuit
B2588 H: Column Lock/Unlock Drive A
B2593 H: Column Lock/Unlock Drive B

AO - LDCM:
B2282 H: Battery #1 Circuit
B2284 H: Battery #2 Circuit
U1064 H: Loss of Communications with BCM

A1 - RDCM:
B2283 H: Battery #1 Circuit
B2285 H: Battery #2 Circuit
U1064 H: Loss of Communications with BCM

A6 - SCM:
B0851 H: Battery 1 Out of Range
B2605 H: Seat Front Vert. Position Sensor Failure

BO - RFA:
U1255 H: Serial Data Line Malfunction
C2120 H: TPM System Malfunction
C2121 C: TPM System Programming Malfunction

Any suggestions on what needs repaired to stop my battery from always being drained...??

Have you had the battery unhooked in the last year (or near dead battery), sometimes this can cause codes. At this point I would clear them all and monitor for anything which may come back.

Yes. I've been having random battery draining issues. I had the two week old battery out and on a charger this weekend. It said it accepted 100% charge and I put it back in to read the codes.

I just took it on a few errands and came up with three changes when I got back:

BCM:
B0433 H: Rear Defogger Relay Circuit
B2528 H: Horn Relay Circuit
B2578 H: Right Front Turn Signal Monitor Circuit
B2583 H: Left Front Turn Signal Monitor Circuit
B2588 H: Column Lock/Unlock Drive A
B2592 H: Column Lock/Unlock Drive B
B2593 H: Column Lock/Unlock Drive B

B0367 H: Right Actuator Feedback Open

AO - LDCM:
B2282 H: Battery #1 Circuit
B2284 H: Battery #2 Circuit
U1064 H: Loss of Communications with BCM

A1 - RDCM:

B2285 H: Battery #2 Circuit
U1064 H: Loss of Communications with BCM

A6 - SCM:
B0851 H: Battery 1 Out of Range
B2605 H: Seat Front Vert. Position Sensor Failure

You should clear all those codes and see which one's come back. Make sure you've got a good battery as many codes can be caused by a low voltage situation.
