Reset button (right side where the Options, etc. buttons are located on the dash).

Check for codes:

If you have codes, post them up.

BTW - very possible that the battery needs replacing if it's over 3-4 years old.

Check your DIC for any codes first.

Sometimes you just have to cycle through the ignition a few times and it will reset itself.

Clear your codes. Because you had a low voltage condition on the PCM from the dead battery. Be sure to get it charged up or replaced.

1) Turn on the ignition but don't start the engine.

2) Press the "RESET" button to turn off any warning messages

3) Press and hold "OPTIONS"

4) While holding "OPTIONS", press "FUEL" four times within a 10-second period.

Initially, on-board diagnostics go into an "Automatic Mode" which shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each module. If none are present in a given module, you will see "No More Codes" on the display.

To reset the codes once in manual mode, press and hold "RESET" until it displays "NO CODES".

Everything should return to normal.

As suggested I'd still check the codes and clear them down. If you had a powerr interrupt you'll have a lot of lost comms codes which would confuse any future diagnostics.
