    Anyone got any ideas why I'm getting a C3400 and C3465 Unknown Chassis DTC?
    2008 Tahoe 5.3 V8 LT.

    The dealer would of course be the best option but I'd prefer to be aware of the problem before letting them loose on the HOE.

    I get my DTC's by using a CarChip from DAVIS Instruments California.
