Fault text
Valvetronic relay, activation: short circuit to positive

Fault description
The diagnostic function monitors electrical control-
activation of the Valvetronic relay for a short circuit to
positive.

Condition for fault identification
Test condition:
The fault is recognized when a short circuit to positive is
detected when activation voltage is transmitted to the
Valvetronic relay.
Potential problem source(s):
- Defective wiring harness
- Valvetronic relay 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
This fault is logged in the control module's fault memory
immediately.

Action in service
- Inspect wiring harness between DME and Valvetronic
relay
- Replace Valvetronic relay
- Replace DME

Fault effect and breakdown warning
Breakdown notice:
None
Possible apparent symptoms:
If the malfunction occurs while the VVT system is at
maximum stroke extension (full load, vehicle parked), only
limited or no effects will be apparent to the customer.
(Switching process may be felt after GD, starting response).
Otherwise breakdown vehicle, as power is no longer
transmitted to the VVT system, which thus closes.
