With the engine off, press and hold the trip
mileage reset button, and then turn the key to accessory position 2 (OBC
and radio come on). The LED display on the instrument panel (which
normally is the odometer) will change to tESt
01 and then will begin to cycle through several
displays. Release the button. The display will continue to
cycle through several displays. Here's the data my car
displays:

Finally, all LED elements will light, and all
gauges will cycle once.
You can press the mileage reset button again to
access more tests. Tests 2 through 4 are always unlocked and hence
available. Tests 5 through 14 are normally locked -- to access these you
must first unlock the display using test 15. Otherwise the display simply
shows: --------.

Distance - used to compare odometer mileage in the
EPROM vs. the coding plug. If the two values don't agree (for
example, if one of these elements was replaced), the manipulation

to the highest value. Press and hold the reset button for 4 seconds,
and the lower mileage reading will be overwritten by the higher, and
the manipulation dot is cancelled. |
