Fault text
Electric fan, activation: short circuit to positive

Fault description
The diagnostic function monitors the wire between the
electric fan and the DME.

Condition for fault identification
Test condition:
The fault is recognized when a short circuit to positive is
present.
Potential problem source(s):
- Defect in wiring harness
- Electric fan defective
Terminal condition: Terminal 15
Voltage condition:
- Electrical system voltage > 10 V
Temperature condition:
- Coolant temperature > -20 °C
Time condition:
- 5 sec.
Other conditions:
- none

Condition for fault memory entry
The fault is logged in the fault memory if it remains
continuously present for longer than 5 sec.

Action in service
- Check wiring harness between DME and electric fan
- Unplug electric fan and then measure resistance on electric
fan between power-supply voltage (Pin 2) and activation
(Pin 4) terminals. If the resistance is less than 10 ohms
respond by replacing the electric fan

Fault effect and breakdown warning
Breakdown notice:
- Probably not possible to activate electric fan, continued
driving at reduced power possible.
Possible apparent symptoms:
- Engine can overheat, breakdown in extreme cases
