Fault text
Valvetronic servomotor, activation

Fault description
Valvetronic servo-motor, activation

Condition for fault identification
Test condition:
none
Terminal condition: Terminal 15
Voltage condition:
none

Condition for fault memory entry
0.3 sec.

Action in service
1. Check wires connected to Valvetronic actuator motor
(CMI-201(O_P_VVT1M) and/or CMI-202(O_P_VVT2M))
2. Measure winding resistance in Valvetronic actuator motor
(between the two terminals), if the resistance > 10 ohms, this
is a certain indication that the Valvetronic actuator motor is
defective. No reliable diagnosis is possible if the results < 10
ohms (measurement precision)
3. If the fault persists, start by replacing the Valvetronic
actuator motor, before replacing the DME
