I posted this in C6 tech, need some help and advice.

I just replaced the wheels and tires on my 2006 mn6 Z51. I also installed a race seat and harness.

I have not yet re-set the TPS.

Went out for a test run.

First of all, competitive driving mode is no longer avaialble.

Second, with traction control OFF, the active handling comes on under heavy cornering.

Is it the TPS ? Or is it the seat that is no londer hooked into the wiring harness for seatbelt and air bag???

Cant go to the track like this. Anyone with direct experience in these issues?

I have rcae seats in my C6Z and the air bag light stays on, but does not effect the Active Handling. Rear tire size and TPS will mess with your Competition Mode and Active handling. Just turn everything off and reset your TPS. If the tire sensors are not reset, after about 50 miles you will get signals to service Active Handling and the car can go to depressed engine mode.

If you using 18'' wheels the problem is with the wheel sensors.
Just pull the ABS Fuse off.

Can you turn everything off? (ie. Hold down the AH/TC button for 5 seconds?)

This is the age old C6 TPS question. :-(

What the heck is the TPS in this context? Throttle postion sensor is all I know and I don't see how seats or tires affect that.

Tire pressure sensor

If you installed the TPS in the new wheels and didn't put the sensors back in the same location they were in before, the TPS System will not work. Each sensor has a unique RF (radio frequency). The monitoring system must be programmed to know which RF is from which wheel location

The system will have to re-learn the sensor location. Until this is done TPS, AH & Traction control will not work.

There is an electronic gadget that is used to "re-train" the system. I borrowed one from a friend and it took less than five minuted to re-set all four wheels.

That is incorrect.

The CPU does not have a clue which wheel the TPS is "really" installed at. It simply thinks it is installed at the location is it already programed for.

Look under your OEM seat for the answer. It's not the TPS.

You could be right. When my wheels got switched, the TPM shut down. Of course, something else could have, and did, go wrong at the same time. The something else was a disconnect of the battery which caused havoc on seat memory, window indexing, etc. So it's possible that the TPM lost memory of the RF of each TPS.

I thought pulling the seat simply took away your telescoping steering wheel. There have been many different rumors about the C6 without tire pressure sensors. Ranging from limp mode, to no Comp Mode, to being unable to turn it all off...

I do not have any sensors on my track wheels and I have no problems at all.

However...if you lose your TP readings on the DIC then AH does exactly what you described. simiple put the road wheels back on and get readings back into the DIC and your set..

the computer shouldn't drop your readings unless you disconnect your battery or clear codes though.

What wheel tire combination do you use?

LOS ANGELES PI

Thanks all for the input.

After the alignment, I had the TPS's reset and voila, all is good again.

Did you try turning everything off before programming the sensors? That's what I'm most curious about. :-)

I made my first trip to MSR in my new Z06 and experienced the same thing. DIC indicated "Traction Off" but active handling still activated on hard cornering. Competition mode was not available.

Difference for me; I drove to the track with race wheels and tires without sensors, the service tire system indicaton was on before I started to run.

I forgot to add that the owner's manual page 284 says that is what will happen.

That's correct. The original poster didn't represent his problem accurately as he said he still had the TPS in the car. Location doesn't matter and they can be in the trunk under pressure and still function for the purpose of the ECU.

Missing is different. I don't have the TPS in mine but if I go park next to another C6 or next to my tires with the TPS in them on my trailer for 10 minutes or so the car will see them and "think" they are there again. Car then performs normally and it's good for 50miles or so before the problem starts over.

MattW_VA saw the same thing when he first started with the track only wheels.


If you think it through I would say the car is doing what it is designed to do. It senses a flat tire and as a result it sort of shuts the car down from aggressive driving.
