+18 Vsc Trac Off Check Engine Light Scion Xb References. I did not use the plastic wrap. My mechanic advised i use 93 octane gas instead of 87 to cure this.
The vsc, trac off lights came on because there is a drivability problem which is why the engine light came on. While doing so i accidentally broke the black piece off. Web it sounds like you may have a vacuum leak somewhere that is causing the evap system to have a leak, therefore affecting power to some of the traction control.
