    • Hi! Many reported that. Apparently this is one of the GEM functions that needs to be activated with diagnostic interface.

  • This is so awesome! I’ve had my focus a year and it just broke down. I had NO IDEA it had this feature until I was looking for ways to diagnose my car. Unfortunately I have to complete a drive cycle though because the battery was changed. Cant wait to get my codes to fix my car.

  • Hey . Thank you . Great trick . But the temperature of my focus 1.4 16 zetec se is 89 to 94 celsius .
    Thank you .

  • hello- thanks for this link

    my car has a suspected overheat problem , can you tell what the ideal coolant and engine temps should be ? and when should the fan turn on?

    • 88-92 on warm engine while driving. It can go as high as 100 but shouldn’t drop below 88-ish.
      You can have thermostat issues, fan issues or even temp. sensor issues.

  • My car is costantly showing glow plug indicator and wont start anymore wat could be the problem

  • is it possible to see the gauge welcome, in every start like the new generation cars,

  • Why does my odometer reading on the hidden menu read more that what it says at the normal dash screen?

  • Hey,
    I just swapped my generator for a used replacement. Replacement has some communication error so the battery warning light is on constantly, but actually it’s charging the battery. I was wondering – does the hidden menu have an option to check the voltage on my battery?

  • Hey! Is it possible to make my ST170 /SVT focus do the needle sweep every time I start up? Thanks!

  • Hi Mr-Fix,
    We have a 2002 Mk1 Ford Focus, and we suspect that the speedo is not reading correctly! It would appear that it is showing a faster speed than we are actually traveling at!?
    Can the speedometer be adjusted or calibrated with these codes?? More over, should we even attempt to do this our selves!?
    Thanks in advance

  • Hi and thanks for this thread. I have an issue with my Ford focus Automatic 2005. While driving all the lights on dashboard displays and it says Engine System Fault, Acceleration reduced RPM gauge goes up and down like crazy. Took it to garage but mechanic doesn’t seem to think it’s electrical issue. Can you help?

  • Hi, i want to save some options. For example i want to save option number 1, GAGE. I want every time when i turn on car to apply this function
