Drive Cycle For Emissions Inspection

[GlennSullivan]

My battery went dead last fall from not driving the car and not connecting the battery tender soon enough. Today I went to get the car inspected and it failed because it had not been driven sufficently since the battery incident caused the computer to see no voltage.

Each manufacturer has a specific "drive cycle" which is necessary to reset the computer after a dead battery incident.

Does anyone have access to the document or know the specific steps for the Viper.

Thanks

The trick here is to use the "bulb check" routine to tell when you have completed the monitors... it's in the owners manual. It will save the trip to the check station.

The other trick while driving is to drive "normally", get out on the freeway and run some nice steady state driving... the monitors run best when they have good info to work from. 5 or 6th gear at legal speeds and have a steady pedal. Big changes in speed/load cancel the monitors...

Use the status lamping to tell when you are ready for the station again... When things are set, it will flash for a bit as part of the lamp test, but then will go steady. If the lamp just keeps flashing you still have incomplete tests. This part is right from the owners manual:

This light is part of an onboard diagnostic
system called OBD II which provides in-field
emissions inspection tests required in some
states. If certain self-diagnostic monitors are
not complete, the light starts flashing 14 seconds after the
key is switched on and will continue to flash for approximately
11 seconds. If the OBD II monitors have completed,
the malfunction indicator lamp will not flash as
described above.​
