Re: How to DISENGAGE VSA-traction control
as to add to what 90sedan said. You need to get a scanner on there and see if there is any history or any other faults that may not trigger a dummy light.
Anything in the PGM-FI menu, or Engine menu, history or current, light on or off will cause VSA problems.
As already stated, check the TPMS menu, even if there is no TPMS or low tire light on, and there is a code stored, this overrides the VSA manual control.
