Condition for fault identification

Test condition:

The fault is recognized when the calculated temperature of the Valvetronic actuator motor rises above 200°C / 65535 (temperature in the windings of the Valvetronic servo motor).

Potential problem source(s):

• Valvetronic system consumes excessive energy owing to:
• Friction and high resistance in the Valvetronic system
• Abuse ("blipping" the accelerator pedal, etc.)
• Frequent open-loop operation (limp-home mode/learning routines)

Terminal condition: Terminal 15

Voltage condition:

• Onboard electrical system voltage between 9 V and 16 V

Temperature condition:

• None

Time condition:

• None

Other conditions:

• none
