Instrument Cluster Test Mode

The Instrument cluster of all US-Spec Foci have a built in test-mode complete with digital speedometer, tachometer and diagnostic readings... Wanna access it? :)

1) Insert Key (do not turn it)
2) Press and hold the Trip-Meter Reset Button
3) While holding the reset button, start your car and continue holding the button.
4) Within 10 seconds, the display should change to "test" (written in a silly LCD font) and the needles will go nuts. No biggie. Release the Button.
5) Pressing the button will now cycle through some 15 different modes.

It's worth me mentioning that this diagnostic mode is no substitute for taking your car in for service. Many codes found in this mode mean absolutely nothing without other, expensive test equipment at the dealership.

Breakdown of some of the functions:
1 Press - Shows a Gauge Sweep
2 Presses - shows all 8's on the LCD (LCD TEST)
3 Presses - illuminates all the bulbs on the dash
4 Presses - displays hexadecimal value for ROM level
5 Presses - Displays the hexadecimal value for EE level
6 Presses - Shows DTC Troubleshooting Codes (Nothing to worry about though)
For the true hackers out there, the following table shows DTC descriptions. As mentioned before, the codes mean very little. Before tests are run, there's lots of steps that need to be taken. If you suspect something is wrong, have your computer scanned with an OBD-II scanner. Many auto parts stores do this for free. Dealers usually charge for this.
