C6 Active Handling System


I have a message come up on my dashboard saying 'Service Active Handling System' and the Traction Control symbol comes on.
Does anyone know how you actually service this system please?

Unfortunately it doesn't mean routinely service an item, it's found a fault somewhere (likely a sensor or connection) and needs further diagnosis.

It should have set a trouble code. Is this C5 or 6?

I should have read this properly, on a C6 it's not as easy tobget codes out of. In fact, I think a normal code reader might struggle as OBD2 only required the manufacturers to make powertrain codes generically available, it may need scanning with a Tech 2 or equivalent...

Re: C6 Active Handling System


If you are lucky it is a wheel sensor or a bad connection.

If you are unlucky it is the EBCM (Electronic Brake Control Module) which is probably going to cost you 1k to replace.

Identify which bit is the EBCM in your engine bay. Drivers side between the engine and radiator. It has a lot of steel brake pipes going in and out of it. On the side of it there will be a wiring harness plugged in. Clean the pins on the connector and cross your fingers that sorts it.

Well, the message has disappeared but I don't trust it. It'll be back.
I've looked under the hood and found the module and connector. Absolutely impossible to get at. Maybe I'll look from underneath and see if I can sneak a hand in.

Steering wheel position sensor was the culprit on mine

Oh yes. I have had that one before too. Forgot about that one. That confuses the active handling. It's a cheap part too. Both in price and quality.

At least with our cars the parts are cheap, and cheaply made, with a Ferrari the parts would be cheaply made and hugely expensive Rofl

Re: C6 Active Handling System


you will need to codes read... I doubt it be the steering wheel position sensor.
The reason why a steering wheel position sensor could cure the problem is down to the plug that connects to it . The telescopic steering pulls on the wiring loom that connects to the SWPS and this causes fretting that can cause this issue.


Easiest is to buy a small comb that plugs into the plug that connects to the SWPS. and it's a GM part fix I can supply one if needed

The active handling service code is only stored if it stays on when you restart the car. It could also be the ABS pressure valve

It wont be the EBCM

I do have a tech 2 . not sure what area you live?

it could also just be dirty contacts on each speed sensor. Unplug each one and squirt some contact cleeaner and reconnect

Re: C6 Active Handling System


You could get one of those OBDII readers that plugs into the port
under the steering wheel and use an App such as Torque Pro to read them.
Would be cheaper than a finding someone with a Tech 2 possibly.
