Put key into ignition and turn it to position 1 (instruments activated).
a2) If you intend driving with diagnostic mode active, start the engine now.
b) Press and hold the trip reset button. This is the button sticking out near the speedometer.
c) Your LCD display will show "test 1.-"
d) Immediately press the reset button every half second until you get to "test 19.-". (19.0 allows access to diagnostic mode)
e) The display will now show alternating "Log 1 -on" / "Log 1 -off"
f) While it shows "Log 1 -off" press the reset button and. .
g) With no delay press within a half second (repeatedly if necessary) to get to the required section.
h) The screen will appear similar to the earlier one, but is a different series. Keep pressing every half second to select one of the following functions (there is no title on screen):
1 Car, Engine and cluster data
1.0 VIN serial number
1.1 K-number
1.2 Cluster Part Number
1.3 Coding (04)/diagnosis (52)/bus index (10)
1.4 Week of manufacture (eg. 1200 = week 12)/year of manufacture (eg. 2000)
1.5 Hardware number (eg. 09) and Software number (eg. 11600 = 16.0) of IPK.
1.6 Injection Status-number of cylinders-motor number
2 Cluster System Test
2.0 Activates the gauge drivers, indicators and LEDs to confirm function.
When function 2.0 is selected, the instrument pack provides a check of the warning lamps, major and minor gauges, displays and illumination functions. The gauge pointers are driven through their full arc and back again to check operation. All warning lamps are illuminated to check that none of the LEDs have failed. All yellow and red pixels of the message centre are flashed on and off in a chequered pattern to check that all elements of the display are functional.
3 Service Inspection (SI) Data
3.0 Fuel Used (in liters) since last Service Inspection
3.1 Periodic inspection days; elapsed days (since last SI)
4 Momentary Consumption
4.0 Momentary fuel consumption in litres/100km (eg. 0145 = 14.5 litres/100km)
4.1 Momentary fuel consumption in litres/hour (eg. 0018 = 1.8 l/hr)
5 Distance Gone Consumption
5.0 Average consumption in litres/100km (eg. 082 = 8.2 litres/100km)
5.1 Calculate distance ( km) to refuel (momentary distance to go)
6 Fuel level sensor outputs in litres (Fuel tank has left and right side sensors)
6.0 Fuel levels both (eg: 109330 means left half sensor = 10.9 litres; right half sensor = 33.0 litres)
6.1 Total tank level (eg: 0439 is 10.9+33.0 = 43.9 litres)
6.2 Indicated value with diagnostics: The Test Number (6.2) is preceded by 1, 2 or 3 (eg. 1-6.2 or 2-6.2 or 3-6.2)
If first digit is 1 - both sensors are OK. This is followed by three left signal digits, then three right signal digits.
If first digit is 2 - one sensor has an error. Side in error will display - - 0 . Functional side will show its three digits
If first digit is 3 - no sensor signal, no display. Probably - - 0 - - 0 (Needs confirming -TC)
7 Temperature and Speed
7.0 Coolant/Engine temperature - changes every whole degree Centigrade. (eg: 021+ is 21°C)
7.1 Ambient/Outside temperature - changes every 0.5 degree Centigrade. (eg.125/130/135 is 12.5°/13.0°/13.5°C)
7.2 Engine speed / Current (RPM)
7.3 Vehicle speed / Current Speed (km/hour)
8 Values of 7.0 to 7.3 in HEX form (Unknown)
9 Battery
9.0 Battery Voltage (eg: 137 = 13.7v)
10.0 Country code
11.0 Unit code
12.0 Not used
13.0 Gong test
14.0-14.4 Error memory: if 000000 no error in memory
15.0 - 18.0 not used
19 Lock Status; unlocks functions in range 3-18 (??)
19.0 Log1-On/Log1-Off Unlocks diagnostic regime: To access, press button when Log1-Off shows
20 Correction Factor for OBC Fuel Consumption display
20.0 The Factor is displayed numerically in the form ABCD (Thousands/hundreds/tens/units)
The formula for the Factor = Indicated Consumption x 1000 / Measured Consumption
The indicated consumption should be established by running the system for several hundred miles, preferably a thousand or so without resetting the OBC at any stage. The longer you allow the un-reset system to operate, the more 'accurate' is the indicated consumption. Determine the measured consumption using brim to brim calculations over a similar period.
Now calculate your more accurate factor using the formula above. These digits are what you insert for ABCD.
Press the button to show 20.1 which allows the units (D) to be set.
The display counts down from the current figure and cycles until you press at the required one.
This sets it and the display will advance to 20.2
20.2 This allows the 'tens' (C) to be set as above. When you press the set button, the display advances to 20.3
20.3 This sets the 'hundreds' (B) and then the 'thousands' (A). Each digit is set in succession by a single press.
After setting (A), the display advances to the next function (21.0)
21.0 Software Reset
Resets OBC settings. Do not press this.
You may now drive the car with the selected display showing for the duration of the journey.
If diagnostic mode is active when you're driving, it will be cancelled when the engine is turned off.
