9 Dashboard

10 Dashboard: MODE button
The MODE button controls several functions on the display and works like a turn-signal switch (move left, move right, press).

11 Dashboard: MODE button

12 Dashboard: MODE button
Use of MODE button By moving the button to the right or left, you can scroll through the functions on the display. By pressing the button you select the function. By continuously pressing the button, you confirm your choice. Sequence of functions: TRIP 1 TRIP 2  BATTERY VOLTAGE  CLOCK MENU For details on the functions (except the menu) refer to the documentation.

13 Dashboard: connections
The signal from the engine speed sensor and the coolant temperature sensor are transmitted via the K-line from the ECU to the dashborad.

14 Dashboard: connections
New connections Antenna on Ignition switch MODE button To the turn-signals Dashboard Vehicle speed sensor Switch turn-signals K-line DLC ECU

15 Dashboard: Immobilizer
The immobilizer system is integrated into the dashboard map. When switching ignition on, the key-code is read. If the code corresponds to one of the code in the dashboard memory, the dashboard starts the initial check and transmits the signal to start the engine to the ECU via the K-line. If the code does not correspond, the engine is not started and the request to type in the code manually appears on the display.

16 Dashboard: Immobilizer
Each customer receives two keys pre-coded transponders. Every time the ingition is switched on, the request to type in the 5-digit personal code appears on the display for 30 seconds. Make sure to input the customer code To input the code, the function CODE MODIFICATION needs to be selected.(See page 18)

17 Dashboard: Menu Menu (after pressing the MODE button for some time)

18 Dashboard: Settings The settings menu allows the customer to set the clock and to modify the code. The menu point CODE MODIFICATION allows the customer to change the code. The old code must be typed in first, then the new code can be entered. For new vehicles the initial code is For more details, check the documentation.

19 Dashboard: Diagnostics
To access the diagnostics menu, type in the service code: For SR 50: 45256 Diagnostic functions:

20 Dashboard: Diagnostics
NEW KEYS function: Use this function to: 1) disable a key in case the key gets lost 2) program 2 additional keys (max. no of keys per vehicle: 4) 3) enable new keys when the ignition switch has been changed First type in the customer code, then, after having had memorisation confirm of the inserted key (the 1st key), insert the others keys you want to program. The procedure is finished after a maximum of 4 keys or after 20 seconds.

21 Dashboard: Diagnostics
MODIFY KEYS function: In case of using a new ignition switch, follow these procedure: Turn key ON, the dashboard don’t recognize the key and ask owner code. Insert owner code. Now, it’s possible to enter in: MENU, DIAGNOSIS (inserting the service code), MODIFY KEYS and start the procedure to memorize new keys.

22 Dashboard: Diagnostics
CODE RESET function: The function CODE RESET allows the dealer to operate in “CODE MODIFICATION” (changing of codes). This is useful, if the customer has forgotten the code number.

23 Dashboard: Diagnostics
CHANGING THE DASHBOARD If the dashboard is replaced, 2 keys need to be inserted and during the same procedure, it’s possible to memorize 2 additional keys.

24 Dashboard: Warnings SERVICE
In the lower part of the dashboard display the following warning lights are shown. These warning lights get switched on together with the general warning light. Coolant temperature Oil level Errors recognized by the dashboard or the ECU SERVICE

25 Dashboard: Warnings These errors are saved as ACT or MEM and are displayed in the diagnosics menu. ECU errors can also be shown with the Game Boy. Coolant temperature errors and oil level errors have a higher priority than other errors. For example: In case of an oil level error and an ECU error only the oil level error is displayed.

26 Dashboard: Warnings The following warnings are also displayed in the lower part of the dashboard display. Communication errors with the ECU Turn-signal lamp faults These faults are not saved to memory, neither in the ECU nor in the dashboard. The message “ECU communication error” also appears when the RUN/OFF switch is turned to OFF, because this interrupts the power supply to the ECU. The dashboard display stays on.

27 Dashboard: Diagnostics
ECU ERROR function The dashboard receives from the ECU regocnized errors or errors from the memory. Selecting this function you can display a table of errors from the ECU displaying ACT (current errors) and MEM (errors in the memory) showed with a X in the relative column as with the Game Boy. The fault code and the explanation of these codes can be found in the troubleshooting table which already have been used for previous versions.

28 Dashboard: Diagnostics
Function: ERROR ECU

29 Dashboard: Diagnostics
DASHBOARD ERROR function The dashboard provides the diagnostics for the immobilizer and the fuel level sensor. With this function you can display the errors table of the dashboard with possibly errors ACT(current errors) and MEM (errors in the memory) showed with a X in the relative column. Even if the transponder code is incorrect or if there is a malfunction of the antenna, it is still possible to start the engine by entering the customer code.

30 Dashboard: Diagnostics
DASHBOARD ERROR function The following table shows the dashboard (DSB) fault code and the description of the error.

31 Dashboard: Diagnostics

32 Dashboard: Diagnostics
Immobilizer and fuel level sensor are found only from the dashboard, for visualize errors it’s necessary show the DASHBOARD ERRORS. All other errors are found from the ECU and shown across the ERROR ECU or with the Game Boy.

33 Dashboard: Diagnostics
DISCONNECT function Dashboard and ECU are connected through the K-line. In order to connect the Game Boy, the dashboard has to be disconnected otherwise there could be errors when reading out the faults. To disconnect the dashboard, select the DISCONNECT function. The following message appears. Dashboard disconnected. Connect Game Boy now.

34 Dashboard: Diagnostics
ERASE ERROR function This function will erase all errors from the dashboard and the ECU. RESET SERVICE function This function will reset the service intervall indicator, which appears at 500km and then strictly at 4000 km and then every 4000 km (8.000, , , …). It’s possible to erase service symbol beginning from -300km in advance to the km forecasted. This function also allows to reset the odometer once, if 200 km have not been exceeded yet.

35 Dashboard: Diagnostics
Km/miles function With this function you can switch between units (km and miles).

36 Dashboard: Diagnostics
REPROGRAMMING function With this function you can fixed up the dashboard for a software reprogramming with Axone Until now there is no new software for Axone about the dashboard.

37 Updates on injection system
A new map is available for this new version 2005 with the Game Boy cartridge 2.8.0 Warning: if you make connection with Axone,you cannot go to the test map for dealer because it corresponds to the old Game Boy version All the other functions are available: engine parameter, control device, error display, etc..

38 Updates on injection system
Connecting with diagnostic instruments, you’ll always found a NOT real error due to the not connection between the ECU and the alalrm lamp (because of only K line exist on this vehicle): with Game Boy shows error: “EFI WARNING LIGHT” with Axone shows error: “CHECK ENGINE WARNING LIGHT” They are errors not to be considered important This error is not showed I n the dashboard

39 Updates on injection system
C361M: Ambient air pressure sensor now inside the ECU ( till now external) Wiring diagram of Ditech and C361M now also show connections with K-line

40 New components: fuel filter
Since July 2004 all new vehicles are equipped with an external fuel filter (until then the fuel filter was located inside the tank) which is more effective.

41 New components: fuel filter
Old filter

42 New components: fuel filter
New filter

43 New components: fuel filter

44 New components: fuel filter

45 New components: fuel filter
It is possible to install the “Filter Kit”, code on the vehicles with the old filter: in case of pump substitution it’s necessary to install the KIT, in order to prevent continuous damage to the pump . Take the old filter out of the fuel tank, and connect the ventilation tube to the new filter, not to the old ring that must be removed. Please note: When you order the old filter or the ring, the new “Filter Kit” is sent automatically.

46 New components: fuel filter

47 New components: quick fit connectors
Ditech engines are equipped with quick fit connectors (since C361M). Kit pressure gauge fuel code New Ditech engines are equipped with quick fit connectors. For connection of an old manometer to the new quick fit connectors, use code

48 New components: spark plug
Beginning January 2005, new spark plugs with platinum electrodes will be introduced for the Ditech engine. Code ZMR7AP . A heat grade 7 spark plug indicates a lower self-cleaning temperature than a heat grade 8 spark plug. Code 2BEN000319

49 New components: Catalyst
Ditech engines now have a catalyst inside the muffler (which also have been used in the Purejet engines). This already prepares the vehicles for Euro3. Operating temperature is approx. 1000°C, which is reached shortly after starting the engine.

50 New components: Catalyst
When using an old muffler of the old engine without without catalyst on a new Ditech model MY 05, not only emissions increase but also power is reduced.

51 New components: variator roller
Together with the introduction of the muffler with catalyst, which influences the engine power, for the Ditech 45km/h also variator rollers of 6.8g (7.7g for older models) have been introduced.

52 New components: Battery
To reduce starting problems, a new battery with 9A/h has replaced the old MF batteries with 4A/h.
