    Default 2001 C5 Z06 Traction Control, ABS and Check Engine Lights Illuminated on Dash

    I have a 2001 C5 Corvette Z06 with Service Vehicle Soon in the DIC when I start the car. In addition the Traction Control, ABS, and Check Engine lights are on in the dash. The below codes were obtained from the DIC code recovery system.
    The car has 73,073 miles. The traction control and active handling lights started coming on in March 2022 with the message to Service Vehicle Soon. The check engine light came on yesterday.
    The HVAC does not work when the car is started. The HVAC does operate intermittently while the car is driven.
    The dealer sent the ABS unit to ABS Fixer for repair in October 2019 to fix code C1214.
    Any repair/troubleshooting guidance would be appreciated. Thanks for any and all help.

    I'd start with the TCM. Check the connections and the grounds. And load test the battery and check it's connections. These cars are very sensitive to voltages. It looks like you also have issues with O2 sensors. So, I'm wondering if they share a ground somewhere.
