Fault text
Valvetronic servomotor, activation, volt phase: Line
disconnection

Fault description
The diagnostic function monitors activation of Phase V in
the Valvetronic actuator motor for open circuits.

Condition for fault identification
Test condition:
The fault is recognized when the current falls below 0.3
amps despite application of voltage to Phase V.
Potential problem source(s):
- Defective wiring harness
- Valvetronic actuator defective
- Defective DME
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

Condition for fault memory entry
The diagnostic fault code is logged when the condition is
present for at least 8 ms.

Action in service
- Check wiring harness between Valvetronic actuator motor
and DME
- Replace Valvetronic actuator motor
- Replace DME

Fault effect and breakdown warning
Breakdown notice:
Engine runs in throttled operation. Normally no limitations
will be noticed. However continued driving is impossible in
worst-case scenario
Possible apparent symptoms:
Range from no effects to power reduction/breakdown
