  • In addition to the above diagnostic modes, the Police (Chaser) Instrument clusters also have a Speedo Calibration mode.
    The Police (Ex-Chaser) instrument cluster allows re-programming of the Speedo Reading, (and consequently the Odometer), so as a Precise Speedo Reading can be made.
    This also means that the Speedo can be re-calibrated, when making changes to the Factory fitted wheels, Tyre Profiles, as well as altering differential Ratios.
    To determine if you have a Police (Ex Chaser) Instrument Cluster fitted, try the following Routine, to enter the calibration mode.
    To Calculate Calibration figures for the Police Instrument cluster, when making the above modifications, please check the Diff and Tyre Calculator Page.

    Warning : Playing with the Instrument Calibration feature will modify your Speedo, and Odometer readings.
    Please be sure of the consequences of changing these settings, and also Make note of your Original Calibration Setting
    This will ensure that you can return the Speedo Calibration Back to its original condition, if modified.

    Entering the Police Instruments Calibration Mode - (Police EF to AU Series I models)
  • 1) With the ignition key in the On position, press and hold the Odometer reset knob for 5 seconds, then release.
  • 2) The Odometer will then display "SPEEDO #.#" - where #.# is the Speedo calibration Percentage, and is set to "0.0" Percent from the factory.
  • 3) To increase the Percentage adjustment, Press the Odometer reset shaft for a short period of time (0.2 to 0.7 seconds). This will increase the adjustment by 0.5%
  • 4) To decrease the Percentage adjustment, Press the Odometer reset shaft for a long period of time (0.8 to 4.9 seconds). This will decrease the adjustment by 0.5%
  • 5) To exit the Speedo calibration mode, press and hold the Odometer Reset shaft for a period longer than 5 seconds.

    Entering the Police Instruments Calibration Mode - (Police AU Series II - AUIII and BA Models)
  • 1) With the ignition key in the Off position, press and hold the Odometer reset knob
  • 2) Turn the Ignition Switch On, and continue to hold the Reset shaft in for 5 seconds, until the cluster enters calibration mode, (Typically 5 seconds)
  • 2) The Odometer will then display "SPEEDO #.#" - where #.# is the Speedo calibration Percentage, and is set to "0.0" Percent from the factory.
  • 3) To increase the Percentage adjustment, Press the Odometer reset shaft for a short period of time (0.2 to 0.7 seconds). This will increase the adjustment by 0.5%
  • 4) To decrease the Percentage adjustment, Press the Odometer reset shaft for a long period of time (0.8 to 4.9 seconds). This will decrease the adjustment by 0.5%
  • 5) To exit the Speedo calibration mode, press and hold the Odometer Reset shaft for a period longer than 5 seconds.
