1. Turn the ignition keys to the run position for 30 seconds and then off for 5 seconds.
2. Turn the ignition keys to the run position for 05 seconds then start the engine
3. let idle for 5 min then got for a drive around town and then out on the high way.
If not check engine light is on then your good to go.
You may find the transmission to shift harder then it used to at first but will adjust it self as you continue to drive the Sonoma.
