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
