Abs inop/trac off
ABS HISTORY CODES, NO CURRENTS comes on right after startup
021 LF NO SIGNAL
025 LF EXCESSIVE
026 RF EXCESSIVE
032 LF OPEN OR SHORT TO GR/BAT
047 LF ABS MOTOR FREE SPIN
Speedo is also off about half (too slow), but the abs problem was present befor this. Has two cheapy for hubs (not fixed) checked the third bulbs. Ion is checking to see if its in the tune for the speedo. I have a DTC90 TCC failure in my M6 car...

Okay, latest and greatest
cruise works, low trac light not on. the ABS INOP and TCS OFF are on after start up and remain on.
I checked the grounds and they are all okay.

21, 25 & 32 are all saying 25 signal from the left front hub is missing, 25 excessive variations in pulses (could be noise) and 32 an open LF sensor circuit. The 26 is saying you are getting excessive variation RF pulses. Since the PCM VSS signal feeds the ABS maybe the speedometer settings could be a culprit. The 47 is different it says the LF ABS motor is freespinning (internal nut or gear linkage), it is not drawing enough current when activated during initial ignition on testing. This may be a fluke. What do you mean by ' two cheapy hubs' are they aftermarket ? All the wheel sensor stuff is internal to the hubs. Unfortunately all the diagnostic stuff in the service manual requires a tech tool.

had an extra pack, swapped it after I found a bad motor inside the pack. I thought the gear was loose on the LF wheel but the motor was the loose part. Replaced all is well
