Condition for fault identification

Test condition:

The driver circuit is deactivated when a fault is suspected. The diagnostic fault code is logged when the voltage measured during diagnosis is less than 0.2 V and the voltage behind the Valvetronic relay is greater than 6 V.

Potential problem source(s):

• Defective wiring harness
• Valvetronic actuator defective

Terminal condition: Terminal 15

Voltage condition:

• Onboard electrical system voltage between 9 V and 16 V

Temperature condition:

• None

Time condition:

• None

Other conditions:

• Voltage behind motor relay > 5V
