Title is a little misleading. My son who is in Afghanistan got a Viper and sent it to me to take care of till he gets back. The Car only has 5,200 miles and looks brand new. My problem is that I went to register it and had to get an emissions test done. The car had a check engine light on it. It failed for a gas cap being bad. Got a new gas cap and disconnected the battery for 20 minutes to reset the computer. Went in for another emission test and failed because computer wasn't working yet. Read the owners manual and found that the if you turn the check key on (but don't start) after 15 seconds the check engine light will flash if the computer hasn't reset. Well I drove it on the highway yesterday for 100 miles. Drove around town for 30 miles and it still hadn't reset. Today after reading the forum I drove down the highway 25 mile and back 25 miles keeping the speed between 50 and 60. The computer still isn't reset. I am going to wait a few hours for it to cool off then check it again. After reading a lot today on the subject it appears that I will need to perform the correct Driving cycles to get it to reset. Does anyone know what the Driving Cycles for a Viper is?? I have 3 days to get the car tagged before the temp tag from another state expires.
