Thread: Cruise control enable E78

    Cruise control enable E78

    I have a 2014 chevy spark with an e78. I installed a steering wheel with cruise control. I'm wondering if I can enable this function in the ecm or if some table or option would need to be added in HP tuners. Any help is greatly appreciated!

    Likely needs to be enabled in the BCM first. Not something HPTuners can do, you'll need to get someone with the ability to program your BCM vis GM SPS or use a dealer. Downside is, if your car wasn't optioned with it from the factory, you may have a difficult time convincing the dealer and/or GM to issue you the updated software.

    You should check the cruise tables in the ECM and/or TCM and make sure they're populated properly, but as for the actual enable/disable, it's (likely) done via BCM.
