I have a 2000 6 sixspeed and the "service traction control light, service ABS, service active handling" light came on after a recient trip over the mountains. It was snowing on the way over,and we spent the night. everything was fine with the car till the next day when we left and i turn onto the road(dry road ,no snow or water) and the car broke traction with me and i get the error messages.
I have read the codes and all it comes up with is a 1217 H .
Could the salt on the way over the mountains gotten into something?
No other codes are stored.
This is strange,any ideas were to start? I have checked all the fuses
and wheel sensor plugs under the car and they seem to be good and tight.

Thanks,
Mike

 

mine did this and is was while backing out of my driveway. trip the code i mean. i had it checked at the dlr and it was the front wheel sensor. they replaced the whole wheel bearing unit. it has the sensors built in. never happened since. somebody on the forum nows how to fix these. do a search on wheel bearing, or wheel sensors you should find the thread.

 

DTC C1217 Pump Motor Relay Contact Circuit Open


CIRCUIT DESCRIPTION
The pump motor is an integral part of the Brake Pressure Modulator Valve (BPMV) , while the pump motor relay is integral to the Electronic Brake and Traction Control Module (EBTCM) . The pump motor relay is not engaged during normal system operation. When an ABS/TCS/Active Handling (if equipped with RPO JL4) operation is required, the EBTCM activates the pump motor relay and battery power is provided to the pump motor.

CONDITIONS FOR SETTING THE DTC
Diagnostic Trouble Code (DTC) C1217 will set anytime the pump motor relay is commanded on and the pump 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 Driver Information Center (DIC) :
Service ABS
Service Traction System
Service Active HNDLG (if equipped with Active Handling RPO JL4)
CONDITIONS FOR CLEARING THE DTC


Condition for Diagnostic Trouble Code (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 Testing for Electrical Intermittents in Diagonstic Aids.
TEST DESCRIPTION
The numbers below refer to step numbers on the diagnostic table.


Checks for a short to ground in CKT 1642.
Checks for an internal short in the Brake Pressure Modulator Valve (BPMV) .
Checks for an open in CKT 1642.


Bill Curlee will have the answer!

 

I had a similar problem on an intermittant basis for a few years on my '01 (though my code was c1214h). I took it to the crooks at Power Chevrolet in Los Angeles and was told that the EBCM and PCM needed replacing, for $3200 - which was more than I was going to spend on an intermittant problem. Then I looked here on the forum, and found Bill Curlee's advice on cleaning the common ground connectors that attach to the frame. With about 45 minutes work, I demated and cleaned both connectors. Voila! No more problem - clearly the folks at the stealership weren't interested in looking for problems than didn't extract maximum money from Corvette owners.

Thanks Bill!!!!

 

I checked the voltage and it was zero. So i went back and looked at the fuses again and i dont know how i missed it the first time but the 40 amp ABS fuse was blown. What could have caused this? and if i just replace the fuse is it going to damage anything ? or could it have been the moisture from the weather when we came across the mountains?

 

mmm 40A is big. Not sure about the salt water...could be. I think I would replace the fuse and stand back.

 

You most likely have a loose connection, Bad pin on one of the plugs or (my pick) a bad ground. The ground for your EBTCM system is in a couple of locations. The first is on the motor/EBTCM it self. There is a stud with a ground wire.
This is NOT your year EBTCM but,,,,the nut and stud look just like the one on this motor!


I would carefully remove that wire and clean it and reinstall. It has a double nut connection. Make sure that you put a wrench on the nut next to the electric motor and DO NOT let it turn inside the electric motor! That ground goes to chassis ground G-101 which is on the drivers side chassis near the rear of the head light.





The EBTCM ground wire should be the large eyelet on the G-101 ground stud under the ground terminal plug.

The other EBTCM ground is near the battery and it is a stud and eyelet type ground:

 

I checked the ground wires last night,took me a while to find my 10mm
deepwell socket though. Went to the parts store today and got a couple of spare fuses today. Changed the fuse and it has done fine all day!
Thanks for the help guys :-)

I have the exact same problem - code C1217 thrown. Mine occurred after I put on my aftermarket rims and spun the wheels one time. Now I have Service Traction and Service ABS lights that won't go away.

Forgive me for being a techical newbie yellow00, but you mentioned you checked the voltage and came up with zero - how did you check this voltage? and where is the fuse that was blown - by the battery or in the passenger footwell?

I don't want to go to the stealership and be told I need to cough up $3200, if I can diagnose this myself.

No need to give the stealer bogus repair cash. Just send it our way!!!

DTC 1217 diffenation is sort of vauge on what is going on inside the EBTCM but there are things that you can test with a volt meter and ohm meter that will prove the system or componet good or bad. Most of it is basic electrical troubleshooting.

There are THREE fuses that you need to check!

Under Hood Fuse center:

Fuse: #52 ABS (40 amp)
Fuse: # 5 ABS/TRNS (10 Amp)

IP Fuse block:

Fuse #8 STP/HAZ ( 20 Amp)

Once you have checked and tested those fuses, Check the grounds.


Get that far and let us know how everything plays out!
