I have a 2000 Coupe that I'm having trouble with the DIC. I'm getting the message service ABS,Traction System and Active Handling. I had the recall work done on the Steering Column from a local dealer but I still get the message "wait 10 seconds and remove the key" message. Some when I hit a bump or something it will trigger the service messages on the DIC. Need help with this annoying problem. I was in Atlanta when I had the recall work done. Now, I'm in Louisville and looking for a dealer to check it. I was told it could possibly be a loose ground wire on the A post.

 

it's your abs wheel bearing sensor , you have to figure out which wheel hit the bump ,that will be your side that will need changing.

 

Do a "SEARCH" for AH/TCS faults, usually code P1214 and you'll get a TON of stuff. Everybody has it, had it, or is waiting to get it. Mine does it off and on and the latest fix was matching tire pressures all around. It came back the next day.

Lots have had success with an EBCM rebuild from http://autoecu.com/ for $158. If you have too much money, go to the stealer and let them hurt you for $1200 -$3600.

I'm going with the $158 and a lifetime warranty on the rebuild.

 

It sounds like you think the DIC is generating "false" messages. While possible, it is highly unlikely. Those messages are generated when other computers in the car post DTC codes indicating there is a problem that they have detected.

Go here and learn how to use the DIC to display the DTC codes posted in those computers.

Write down the codes (easiest done in manual mode) and post the codes here and someone can help you in determining what they mean and what it takes to fix them. Post the ENTIRE code ... that is a letter (P,C,B,U) followed by 4 digits, followed by either an H or a C (sometimes both. Code will look something like .... P0310H

I have a 2001 Corvette with manual transmission, which I have only had for 30 days. I drove it this past weekend on a road trip to shake out any problems not yet experienced. During the trip my Cruise Control disengaging without request at least three times, but I could reset it without a problem and no error message on DIC. On the return trip, the Cruise Control started acting up again but with in a 15 to 20 minute period it had disengaged several times. I then turned off the Cruise Control and continued to drive without it. Approximately 10 - 15 minutes later, I felt the car pulse to the left. At first I thought I hit a pothole on the interstate, but a few minutes later it did it again followed by an error message to have the Active Handling Serviced. I turned off the Active Handling and continued to drive. About a half hour later I decided to turn on the cruise to determine if the Active Handling had been affecting the Criuse Control. Cruise worked fine all the way back home. I stopped half way through my trip, and when I restarted the car the Active Handling Service message was gone. Active Handling remained off for the rest of the trip, but since then I have been driving the car without any problems or error messages. Thanks to the directions on this site, I read out the error code which was C1287H - Steering Sensor Rate Malfunction. I have an appointment next week to have the car looked at, but I was wondering if there is anything else I could do or just wait. I am having no other problems with the car.

 

cwmartin59,

Good diagnostics ... any time AH or TC kick on, the EBCM immediately commands the PCM to turn OFF Cruise Control. By running with AH off, you isolated the problem to the car getting "false" readings that caused the EBCM to engage AH. Those readings were probably the steering wheel position sensor (if the yaw rate sensor, or the accelerometer were messing up, that would post different codes) based on the code.

Yup, C1287 indicates a possible failing steering position sensor. However, the diagnostics in the manual have the tech test certain outputs from the sensor first, as it could be a wiring problem (loose or corroded connection) rather than the sensor. If the sensor tests good (which it might if it is an intermittent fault) then the diagnostics step you through testing the EBCM. Usually, though, if the EBCM has a problem it sets its own codes. So ...

Check the wiring around the sensor and at the EBCM for loose or corroded connections.

If everything checks OK, then replacing the sensor is the next logical step.
