Had the wot defeat for a few years, no problems. Wife went to drive the car and got the shvcs message today and the car won't charge. Stuck at work so I'll check the coolant levels when I get home but not sure where else to start digging around. I'll order a vcx nano so I can reset it in case a normal obd2 won't. Is there any way to test the defeat to see if it has failed?
