Paperclip test
Open fusebox under steering wheel. Straighten a paperclip, and insert as shown:
Turn on ignition, and count the flashes of the EML. Easiest way to describe is to watch this video:

Note: On a v6, if the engine isn't running, it is normal to get a 31. On a v6, you can do test again with engine running.
Note: Systems using 2 digit codes (2.5/3.0 and earlier 2.0), the system flashes a 1-2 (12) 3 times to indicate start of
sequence. Systems using 4 digit codes (later 2.0l), there is no start of sequence - it starts flashing out fault codes (if
any) immediately.
