Hello all,

I had my transmission and rear replaced recently now I am receiving service active handling. The AH system will randomly engage then disengage at speed even on the highway

This NEVER happened before.

The shop says they didn't touch anything having to do with the system. Any ideas?

The car is a 2001 C5 Z06.

 

AH and TC rely on numerous sensors to determine if they need to intervene. Perhaps a wheel speed sensor wiring harness was damaged during the R&R of your drivetrain. In any event, pull your codes from the DIC (Hold Fuel, press Options 4 times) and research each one. Specific codes will be logged when abnormal results are being received from those sensors, and the "Service Active Handling" message appears on the DIC. After researching the codes, clear them all out and watch for new ones to appear after making the necessary repairs.

 

I agree with the above.

Sounds like either you're experiencing a wheel speed sensor issue or you have an unrelated issue with your steering wheel position sensor. (Or possibly the combination of the two.)

 

I have a ground that vibrates loose that started after trans rebuild will come on when I hit a bump guy that replaced trans just tightened it up has just started back a second time after 10,000 miles but it doesn't turn off until car has been restarted
