Indicator lamp will come on for 20 seconds. Ignition switch to ON (II), without starting the engine. It takes at least three days of driving under various conditions to set the codes again. If your vehicle battery has been disconnected or gone dead, these codes are erased. If they are not set, the test cannot be completed. In some states, part of the emissions testing is to make sure these codes are set. Your vehicle has certain ‘‘readiness codes’’ that are part of the on-board diagnostics for the emissions systems.

There is a very specific drive cycle (at least for my I4, keep in mind both the I4 and the V6 have the same exact manual so it should be the same) and it is mentioned in the drivers manual.
