    Default Service Traction Control and ABS Display

    My 2003 Z06 with 31,515 miles on it just started displaying the "service traction control, service ABS" warning. I have the following codes In the DIC:
    10-PCM P1431H
    28-TCS C1214H C
    A0-LDCM B2282H
    A0-LDCM B2284H
    A0-LDCM B2264H
    A0-LDCM U1064H
    A1-RDCM B2283H
    A1-RDCM B2285H
    A1-RDCM U1064H

    I think that the 28TCS C1214H C is the key here. Are there any wiring connections that I should check? Does this indicate that a particular electronic component has failed? I would appreciate any input as to the potential source of this problem. Thank you.

    Check speed sensor on hubs. Each will have a plug from bearing hub.

    I believe c1214 is a low voltage code within the ebtcm
    If the battery is good
    Here is the fix

    I just noticed that the part listed in that post is discontinued

    I found the replacement part here
    http://www.sourceresearch.com/Store1...2290&do=detail

    Funny thing, I replaced both of my front wheel bearings and the next day when I was off to work that code came up.
    I thought "s#!t, now what"?
    When I started it up after work the lights were still on. Stopped at a C-store on my way home for some spirits and when I started it up the lights were off. So I was thinking that the battery was charged from driving and replaced it the next day.

    No more lights for 2 weeks, now it's back on. Time for the relay repair I guess!

    Not a month after I bought my 03 Coupe in March, did I start getting the C1214. Pull all the wheels and checked connections and cleaned, took the two front grounding unit's apart and cleaned. Still would come on once in a while. For a week or so, every time I would hit a good bump in the road, bingo, on. I'd drive the car 10 or so miles , shut it off, restart, dash cleared. Got to where it stayed on more than off.
    Found my HP hose from the powersteering leaking and loosing PS fluid so changed that line out. Really having to turn the front wheels back and forth lots to reprime the Power Steering system. First, with a dead engine, then with it running to make sure all was primed and full. Amazingly, no ABS/Trac Control light for about a week. Then pull front wheels off and clean rusted hubs about the Brake Disk. What! No light on the dash for about a week. Opened and closed the hood. Hmmmmmm light on. after about 20 miles light off after a restart. Wierd car.
    Pretty sure it's a bad wheel sensor but really not gonna get excited about it. I'll just double chek all next time I have any of the wheels off.

    is it possible to get a C1214 code from a wheel speed sensor issue?
    If so
    That would explain my light on!

    I believe that the C1214 code is triggered by a faulty EBCM.

    I removed the EBCM and sent it to a repair shop in Missouri to have the faulty component replaced and a surge protector installed. I installed the repaired unit in my car and there are no codes.
    If you are going to perform this job I suggest that you remove the upper radiator hose and the air bridge as that will make the job easier. I would also suggest magnetizing your torx driver so it will hold the screws.

    What did the unit cost to get repaired?

    I sent the EBCM to Brandon Hite at ABSFixer.com in Missouri. He charged $150.00 for the basic EBCM repair and an additional $50.00 to install a surge protector. You are also responsible for the shipping fees.
