Hi, So I took my C5 to Van Bortel in Macedon and had new tires and (Z06) wheels put on the car. Now I am getting "Service Active Handling/Service ABS/Service Traction Control" warning lights on the dash.Can I reset the codes so they go away? Also, can anyone recommend a good shp near Lyons, New York to take the car to? I really was not impressed with the way Van Bortel handled this whole thing and calling them back,I am just getting the run-a-round.

 

Check to make sure all of the AH/ABS plugs are secure by the shocks. This tripped the same warnings for me as well when I had an alignment done. Also, did the TPMS get activated properly on all four wheels?

 

The tires,BF Goodrich Sport Comp-2, I had put on the Z06 wheels were 255/45/17 front and 275/40/18 rear and before I even bought the tires I checked and their service dept said I would be fine. Now they say the front tires are turning faster than the rear tires,and that's why the codes are activating, and I should have bought 245/40/17's for the front! What a nightmare, now I am concerned about driving the car. They took the sensors off my stock wheels and put them on the Z06 wheels

 

The tire sizes aren't likely the problem. If they didn't put the sensors back in the same position as original, you probably need to do a re-learn. Your front sensors might be in the back now, for example.

 

Trying to talk to this dealer is like pulling teeth now, the conversation just goes to he said,she said, and I really don't want to take the car back there. I have called two different Speed Shops here and both say I really should get the correct tires for the Z06 rims and that would solve the problem.

 

I really think you should try a sensor relearn before spending money on new tires again. Since my z06 doesn't have the system, I don't have first hand knowledge of the procedure, but it seems simple enough.

Just got off the phone with Tirerack and its the Z06 wheels that are the "real" problem because I put them on a stock C5. Now I am screwed, cant use the tires or the wheels!

 

No. There are numerous C5s here that have z06 wheels and all sorts of other aftermarket wheels without any problems. You need to get the TPMS sensors relearned and go from there. The dealer that installed your wheels/tires should have done this for you, and you should really go back and make them do it. But if you really want to avoid that dealer, go to a different one, they might charge an hour of labor.

Or click the link I gave you and learn how to do it yourself for free.

 

The wheels are definitely not the problem.

You can relearn the sensors yourself with a speaker magnet. I just did this on Saturday because I had a single TPMS replaced. Takes 3 minutes tops. Four if you walk around the car slowly.

 

Stop talking to these people. Whoever told you that needs a new job.

Those front tires are 26" diameter.
The rears are 26.7" diameter.

Physically impossible for the fronts to be turning faster.

The stock tires are 25.3" front and 26.1" diameters.

You are 0.1" closer together than stock. This won't be your problem. Relearn the sensors.

 

Thanks for all your help, for now it's going to sit until I can sort it all out. All said and done this ordeal just cost me $2200 in tires and service charges at the dealer so I need to figure out what my next move is going to be.

 

Your next move is to get a magnet and relearn the sensors for free. It sounds like you're making mountains out of molehills.

TPMS relearn procedure:

Programming Procedure

1. Turn the ignition switch to the ON position. (Engine should be off.)
2. Press the RESET button on the Driver Information Center (DIC) to clear any Instrument Panel Cluster (IPC) warning messages.
3. Press and release the OPTIONS button on the DIC to cycle through the display options until the IPC display becomes blank.
4. Press and hold the RESET button until the “FOB TRAINING” message appears.
5. Press the OPTIONS button once and a “TIRE TRAINING” message will appear.
6. Press the RESET button once and a “LEARN L FRONT TIRE” message will appear. This message signals the beginning of the programming sequence.
7. Hold the Tire Pressure Monitoring System (TPMS) Programming Tool over the valve stem of the left front wheel. When the horn beeps once, programming is complete for the left front wheel ONLY. NOTE: You may have to move the tool around the valve stem to hit the right spot.
8. After the horn beep, proceed to program the remaining three sensors. You MUST program the sensors in the order directed by the IPC messages.
9. The order of programming is fairly simple to follow. First, start with the (1) LEFT FRONT WHEEL. Wait for the horn beep. Then, move to the (2) RIGHT FRONT WHEEL. Wait for the horn beep. After, move to the (3) RIGHT REAR WHEEL. Wait for the horn beep. Finally, move to the (4) LEFT REAR WHEEL. Wait for the horn beep.
10. The programming/reset process has successfully been completed at this point.

 

This! You presumably came here for advice, and it's been given to you. Stop freaking out and relearn the sensors.

 

Everyone here has told you what you need to do. Start with re-learning the sensors. Tirerack and the speed shop you talked to don't know what they hell they are talking about. All they want to do is sell you new wheels and tires.

 

The C5 corvette tire ratio must be followed to a T. The rear tires must 1 inch taller than the fronts or the "Service Active Handling/Service ABS/Service Traction Control" warning lights on the dash will come on. I will try and find the post talking about it. If you choose a different ratio it will effect the C5 corvette. If the ratio is less than 1 inch or more than 1 inch or it will effect the abs etc. You can check at www.tiresize.com (Tire height calculator), also check out the rpm calculator you will be able to see speed difference. Original tire size c5 front 245/45-17 = 25.7 inch rear 275/40-18 = 26.7 inch 26.7 -25.7 inch = 1 inch Ratio
Your setup Front 255/45-17 = 26 inch, Rear 275/40 - 18 = 26.7 inch 26.7 - 26 = .7 inch less that 1 inch ratoi
You are .3 inches off, you will need 2 new rears or 2 front tires, you have to get the ratio to be 1 inch!!!!! The corvette computer wants to see 1 inch in height between front and rear tires, the computer can tell buy the abs etc.

 

What codes do you show?

 

Should still be fine. People run square tire setups on Z06 rear wheels without interference.

Since when does the tire pressure sensors cause a "Service Active Handling/Service ABS/Service Traction Control" warning light? I've had tire pressure sensors not working and they did not cause that warning light. They cause a message on the DIC though.
OP, don't freak out. I run Z06 rims on my coupe and have absolutely no problems. I would guess what scorpiofox69 replied, I'd be checking the AH/ABS sensors. Do you know how to pull codes on the DIC? The codes will tell you what sensor or if it's the EBCM.

 

I was wondering the same thing. I thought I had missed something.
