3.7 Protective functions
3 Description
3.7 Protective functions
The engine has an engine diagnostics, which monitors various operating parameters. The protection
functions described in this chapter are intended for your protection and to protect your engine when the
operating parameters exceed defined limits.
Protective function Description
Coolant temperature Temperature variations during engine operation are normal. Therefore
the protective function will be activated in several stages, to protect the
engine from overheating.
Coolant temperature 91 – 110 °C
The temperature range can occur due to operational temperature
variations. The engine output is reduced continuously with increasing
temperature to about 60 %.
No measures are required.
Coolant temperature 111 – 115 °C
The temperature warning light illuminates and the engine power is
reduced to about 30 %. The critical coolant temperature has almost
been reached.
Measures are required. (See chapter 3.9.1 Lights in vehicle.)
Coolant temperature > 115 °C
The temperature warning light and the malfunction indicator light
illuminate at the same time. The engine power is reduced to about 25
% and the engine speed is limited. The critical temperature range is
reached and an engine damage caused by overheating is imminent.
Measures are immediately required. (See chapter 3.9.1 Lights in
vehicle.)
Temperature intake air The protective function is activated when the temperature of the intake
air exceeds 35 °C. The engine output is reduced continuously with
increasing temperature.
Throttle control pedal / Brake
pedal
Observe that the engine power is reduced during vehicle operation
when brake pedal and throttle control pedal are actuated at the same
time.
Roll over detection If your vehicle is equipped with a roll over detection, the roll over
detection will be activated under specific operating conditions. (See the
vehicle manufacturer‘s documentation.)
In this case the ignition, fuel injection and the fuel pump will be
switched off immediately.
For resetting this protective function, turn off the ignition switch and turn
it on again.
