Ford Focus test mode

2018-01-05

The Ford Focus Mk 1 has a very convenient test mode accessible from the dashboard.

Entering and leaving the mode

This will reset your trip meter!

To access the test mode:

  1. Start with the car off.
  2. Hold the trip reset button down.
  3. Turn the key to the "on" position (not necessarily starting the engine).
  4. Let go when test appears on the odometer.

To exit, turn the key to the "off" position.

Available diagnostics

There seem to be some differences (likely between regions and years), so this table might not exactly match your experience.

It automatically starts in the first diagnostic. Switch to the next one by pressing the trip reset button. After the end, it loops around to the beginning.
