Question about Traction Control
I have a 2004 C5 that occasionally displays the "Service traction control" message on the dash. Along with this, frequently when braking I can feel ABS kicking in when it definitely should not be (dry roads, sunny day, perfect road conditions).
I just cleaned the ground below the battery and the ground splice pack near the front of the engine (I don't know how else to describe it). After I cleaned these I cleared the codes and continued to get these same 6 ABS/TC codes:
C1121 - LF WHEEL SPEED SENSOR INPUT SIGNAL IS 0
C1222 - RF WHEEL SPEED SENSOR INPUT SIGNAL IS 0
C1242 - BRAKE PRESSURE MODULATOR VALVE PUMP MOTOR GROUND CIRCUIT OPEN
C1248 - DYNAMIC REAR PROPORTIONING (DRP) DISABLED
C1278 - TRACTION CONTROL SYSTEM (TCS) TEMPORARILY INHIBITED BY POWERTRAIN CONTROL MODULE (PCM)
C1287 - STEERING SENSOR RATE MALFUNCTION
Should my next step be to do the EBCM solder fix?
Any and all help is very much appreciated!

That's a pretty good list of codes. It does seem like there ought to be a singular cause for all of them, would be quite the coincidence if they're all occurring separately/on their own.
Only chiming in here because I started looking into EBCM stuff... last night my '01Z threw a C1214 code that wouldn't clear, and that code is the EBCM 'death' code from what I understand. Without C1214 I don't think EBCM solder fix will help, but it also won't hurt as apparently these EBCMs will all eventually need solder fix.

Contact ABS fixer on the web. See if he believes he can fix these. These are a
