- Warming up cycle
The warming up cycle refers to the riding cycle
which allows to increase water temperature to at
least 22°C above the temperature at the moment
of the engine start-up, reaching at least 70°C.
- Riding cycle
The riding cycle comprises the engine start-up and
stop.
N.B.
- THE CODE CAN BE CLEARED IN ABOUT 30 SECONDS.
IN SOME CASES, HOWEVER, MORE TIME COULD BE RE-
QUIRED. BESIDES, THE CODE CAN BE CLEARED BY DIS-
CONNECTING THE CIRCUIT, AS WELL AS THE BATTERY
POWER SUPPLY AND FUSE CONNECTION. IF THE BAT-
TERY TERMINAL MUST BE DISCONNECTED, TAKE NOTE
OF THE RADIO CHANNELS. AFTER FINISHING THE OP-
ERATION, SET THE RADIO CHANNELS AGAIN.
- IN CASES IN WHICH THE SAME MALFUNCTION IS NOT
DETECTED ANYMORE DURING THE COURSE OF THE 40
ENGINE WARMING UP CYCLES, THE FAILURE CODE AND
FROZEN IMAGE DATA ARE CLEARED AUTOMATICALLY
FROM THE CONTROL UNIT MEMORY (ONLY IN VEHICLES
WITH EU SPECIFICATIONS).

Diagram of basic operations to check the engine
If the electronic control unit does not detect any diagnostic failure code during the malfunction phe-
nomenon test, and during the visual inspection no failure is detected, perform a progressive trouble-
shooting of circuits which are presumably the cause of malfunctions. In many cases, the areas causing
malfunctions can be quickly and efficiently identified by carrying out a basic check of the engine, as
indicated in the following diagram. Therefore, it is very important to carry out these checks to identify
engine failures.
1. Check that battery voltage is equal to 11 V or more, with the engine stopped
Charge or replace the battery, if necessary.
2. Check that the engine runs with the starter motor
3. Check if the engine does not start
•
Proceed with step 6, otherwise proceed with step 4.
