DESCRIPTION AND OPERATION
The following table shows the code and abbreviation for the available markets. Note that the on-board computer
language variants for CDN, AUS, GULF and ZA use the same display texts as GB.
The country code does not only define the language displayed in the message centre, but also defines if the odometer/
trip meter display is in miles or kilometres and if the temperature display is in Celsius or Fahrenheit.
Test Function No. 11 – Read Units Display
l
This function is locked and needs to be unlocked via the procedure in Function Test No. 19. The following data
can be scrolled through using the trip reset button.
The unit coding of the on-board computer, clock and ambient temperature is programmed at the factory during
build and is stored in the EEPROM. This coding can be queried using this function. The unit coding is shown in
hexadecimal form for each individual byte. The following shows the coding for bytes 1 and 2. When byte 3 is
reached the display changes to byte 1 again.
l
'EINHEIT 1: 00' – hexadecimal value for byte 1.
l
'EINHEIT 2: 00' – hexadecimal value for byte 2.
l
The units for
°
C or
°
F or 24 hour or 12 hour clock for example, can be changed using TestBook/T4 to change the
bit assignments for bytes 1, 2 and 3. Refer to TestBook/T4 for details of units which can be changed.
Test Function No. 12 – Average Speed for Arrival Time Calculation
l
This function is locked and needs to be unlocked via the procedure in Function Test No. 19. The following data
can be scrolled through using the trip reset button.
This function shows the average speed used for calculation of the arrival time and also the momentary arrival
time value.
l
'VANK: 136.5 km/h' – this shows the average speed used for arrival time calculation.
l
'ANK: 23:46' – this shows the momentary arrival time.
l
The calculation of average speed uses signals from the ABS ECU for speed and distance to produce the average
speed value. After the system is reset, a default average value of 40 km/h is used, until the vehicle is moving
again with the engine running.
When the vehicle is stationary, with the engine running, the calculation of average speed is interrupted. The
arrival time is adjusted by monitoring the clock. Every full minute that passes on the clock, with the vehicle
stationary, is added to the arrival time.
Test Function No. 13 – Activation of the Chime Signals
l
This function is locked and needs to be unlocked via the procedure in Function Test No. 19.
This function provides for testing of the instrument pack sounder in the fascia closing panel, below the steering
column. When the function is selected, 'CHIME?' appears in the message centre. Pressing the trip reset button
once activates the three available chime signals as follows:
l
Chime T1 – activated for 100 milliseconds with a 2.5 second pause. Used for the MEMO signal.
l
Chime T2 – activated for 100 milliseconds with a 2.5 second pause. Used for the Ambient temperature
warning.
l
Chime T1 and T2 – activated for 100 milliseconds with a 2.5 second pause. Used for LIMIT/CODE warning.
l
Chime T3 – Activated for 100 milliseconds with a 2.5 second pause. Used to indicate check control
messages.
