I've got the service active handling, ABS, traction control lights and chimes. Anyone know a quick and painless way to get rid of or fix this problem?

Mr.Bill

I have heard ABSFixer car repair them.

The first thing you must do is check for codes to see what the problem is as it could be many different things.

Wade,

You need to post your code(s) in order to get an accurate diagnosis - Many others on the forum have had similar issues with our ABS

Jistari

Yup, cant assume its the EBCM (thats the thing you pull and send to ABSfixer) until you poke around, see if the grounds and battery are good, and check the codes.

If it does turn out to be the EBCM though, the ABSfixer route is quick, not mechanicaly difficult, doesn't take the car out of service (you can still use the car with it out) and fixes it better than new (yes, better than a new off the shelf EBCM).

I've had this problem and would like to know about the grounds and battery. Where do I find the code it may be throwing? Exactly where is the EBCM located? Think I know but not positive.

Here's what mine has done. Please let me know if I'm on the right track.
At times it will say service ABS / TC when I first start the car. If I turn it off, pull the key, etc. it doesn't do it for a while. The last time it did it, which was about a month since it had done it, I got on it pretty hard and when it went to 2nd gear it did it. Hasn't done it since. Please help me out.

Thanks!

See post #5 for checking codes.

csc67

Dan,

Pull the codes and list them (see post # 5 to pull codes) - Start with codes first

ABS Fixer doesn't fix EBCM's that are 1997-2000

The two experts are Bill Dearborn & Curlee - Use the search function or PM me for more information

The part with all the tubes is your BPMV and the part with the 'M' is your EBCM - You can see that I'm pulling the rad. hose to the side to get the picture

I have an 01 and I had the Service Active Handling and Traction Control message also. As already stated check your codes and post them. I have a warranty and mine was a wheel position sensor. The dealership repaired it in a few hours, and it cost me $85.

C02VETTE

Mine would do it only when i turned the wheel full either direction. After i lowered it, it never happened again. Loose connection i guess. Just make sure it isn't something as simple as that before you start replacing anything.

DP77Vette

Thanks to all! I'll check the codes and be back later today or tomorrow.

Thanks again!

Dan

Thank You to everyone for their time and advice. This forum and its respectable guests, is awesome. I've fixed several problems without spending any labor dollars, all on the account of fellow corvette drivers from this forum. You guys are great, Thanks Again!

Wade

important

Thumbs up to that

Guys on here are phenomenal.

28tcs-c1214

csc67

Wade,

Usually the 1214 is the 'kiss of death' - You could try cleaning the grounds, but most people just send it to absfixer or other companies - Price ranges from $60 - $150

You have to take it out and send it the companies that re-build these units - There are lots of threads on forum that describe how to remove the ECBM

Consider yourself VERY lucky to have a 2002 - For owners of YR 97-00 vettes, we have to buy new EBCM that run $600+

Hope this helps

DTC C1214 Solenoid Valve Relay Contact or Coil Circuit Open, the common one! If the service light is always on check fuse 20A ABS ELEC Maxifuse®, in the Underhood Electrical Center. Check the condition of the wire harness to the EBCM, were the harness passes in front of radiator cooling fans can be a problem area. Since you have a 2002, absfixer can possibly repair your EBCM.

If you are handy with a DMM, here are more checks you can do to help nail down the problem:

DTC C1214 Solenoid Valve Relay Contact or Coil Circuit Open




Circuit Description
The solenoid valve relay supplies power to the solenoid valves in the BPMV. The solenoid valve relay, located in the EBCM, is activated whenever the ignition switch is in the ON position and no faults are present. Power is provided to the solenoid valves through the relay from CKT 1242 going into terminal D of the EBCM. The solenoid valve relay remains engaged until the ignition is turned off or a failure is detected.

Conditions for Setting the DTC
DTC C1214 will set anytime the solenoid valve relay is commanded on and the solenoid valve relay voltage is less than 8 volts, and ignition voltage is greater than 10.5 volts.

Action Taken When the DTC Sets
ABS/TCS/Active Handling (if equipped with RPO JL4) are disabled.

Indicators that turn on:
ABS indicator
Car Icon (TCS indicator)
Messages displayed on the DIC:
Service ABS
Service Traction System
Service Active HNDLG (if equipped with Active Handling RPO JL4)
Conditions for Clearing the DTC
Condition for DTC is no longer present and scan tool clear DTC function is used.
Fifty ignition cycles have passed with no DTCs detected.
Diagnostic Aids
It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
If an intermittent malfunction exists refer to Intermittents and Poor Connections in Wiring Systems.
The Relays are integral to the EBCM and are not serviceable.
Test Description
The numbers below refer to step numbers on the diagnostic table.

Checks for a short to ground in CKT 1242.

Checks for an internal short in the BPMV.

Checks for an open in CKT 1242.

Bill, could you please send me you tutorial at your convenience? Thank you, sir !! wineczar@gmail.com

I guess I will throw my 2 cents into this............... my car is highly modified and uses more electric power. I started to have the same problems although all grounds were clean and
a new battery. I have a 2000 with a 110 generator , I finally decided the wires were getting old so I bought a 200 amp generator and problem solved. So far.
Good luck
