What does it mean for a vehicle to be “Not-Ready”?
“Not Ready” failures imply that a vehicle’s readiness monitors have not been fully reset. The onboard
computer resets anytime there is an uncommon electrical event within the car. The most common
causes are removing the battery cables, jumpstarting another vehicle, adding out-of-market electrical
equipment to the vehicle, and clearing DTCs from the computer. When the onboard computer has been
reset, the vehicle must be driven in a certain manner determined by the manufacturer, called a ‘drive
cycle’. This drive pattern usually involves a normal combination of city and highway driving for about
two weeks. Contact your vehicle’s manufacturer or LDEQ for specific drive cycles. There may be
nothing wrong with your vehicle. After completing the drive cycle, return the vehicle to the motor
vehicle inspection station for a retest.
