It is my experince that this procedure must be followed to the letter on reconnecting the battery. I have posted this previously but could not find the link, still always worth a reminder.
Following reconnection of the battery, the engine should be allowed to idle as the stored idle and drive values contained within the powertrain control module (PCM) have been lost. This may cause driveablity concern if the following procedure is not carried out.
1) Connect the battery negative cable.Tighten to 4 Nm.
2) Start the engine and allow to idle until the engine reaches normal operating temperature.
3) Switch the engine off.Restart the engine and allow to idle for approximately two minutes (this will allow the PCM to learn the idle values).
4) Apply and hold the brake pedal, select drive and allow the engine to idle for a further two minutes.
5) Drive the vehicle for approximately five miles/eight kilometers of varied driving to enable the PCM to complete it´s learning strategy.
6) Reset the audio unit and climate control assembly to original settings to avoid customer complaint.

Further, if any OBD monitors have not set then see JTIS again (codes PDF).

That's the shop process that returns a car to a waiting customer so he doesn't wonder why his favourite radio station is missing or why the car idles differently for a few minutes.
Not much value and just wasted time and fuel for a DIY type.

After battery reconnection, before cranking, Ignition in II, slowly depress the accelerator through to it's full span, hold 5 seconds, slowly release, wait 5 seconds. Repeat a total of three times. Ignition to 0.
