Now if I can only find out what the Saab "drive cycle" is... I particularly like how vague option 1 is.
MY VEHICLE DID NOT PASS BECAUSE THE OBD COMPUTER IS "NOT READY".
· The proper operating or driving conditions (see *drive cycle below) for your vehicle have not been met, and the OBD computer has not completed its self-test to determine the performance history of the vehicle’s emission control system.
· A vehicle’s OBD computer may be "Not Ready" as a result of recent maintenance or if the vehicle’s battery has recently been replaced or disconnected. Again, the vehicle must be driven to complete its drive cycle.
· After completing the drive cycle, we recommend having the repair technician or emission inspector pre-scan the vehicle to determine if it is "Ready" PRIOR TO RECEIVING A RETEST.
· As always, we recommend receiving an emission inspection 4-6 weeks prior to the registration renewal date, usually the vehicle owner’s birthday.
HOW CAN I "READY" MY VEHICLE FOR AN OBD INSPECTION?
There are three (3) options:
1. Provided there is time before registration, you may choose to drive the vehicle under normal driving conditions for 1-4 weeks, which should include some highway driving. After at least a week of driving, you could go to a repair shop/dealership and ask to have your vehicle’s computer scanned to determine if it is "Ready". Be sure to ask for a cost estimate prior to authorizing this service.
2. A repair technician can complete the drive cycle on the road or by driving the vehicle on a dynamometer ("treadmill" for vehicles). Be sure to ask for a cost estimate.
3. The vehicle owner can complete the recommended drive cycle. Ask the dealership or vehicle manufacturer for written drive cycle instructions.
*WHAT IS A DRIVE CYCLE?
· Drive cycles are specific driving procedures designed by vehicle manufacturers to "Ready" their vehicles so the OBD system can perform its self-tests.
· Specific drive cycles can be obtained from the vehicle manufacturer or other sources that supply information to the automotive repair industry.
· Remember to check warranty coverage on your vehicle for emission related repairs.
