tor light blinking from idling
to approximately 1300 rpm
Engine test with Modus-IWT-IT2000
Replacement of defective injector, if
any
The control unit must modify the signal to
the relevant injector (Cylinder Balancing)

wards the involved cylinder
Engine running with 3 cylin-
ders
Check for leaks outside injector pipes
or inside the injector
Do not switch off the engine since it will re-
start only after having removed the failure

Battery voltage too low
Accelerated idling up to
1300 rpm with released
pedal
Battery test with IWT-IT2000
Perform suitable checks on voltage
regulator and batteries

Battery voltage too low
Engine switching off or not
starting
Battery test. Check battery, terminals,
wiring, alternator and voltage regulator
