Start diagnosis
-
Disconnect the Intake Flap Motor (V157) electrical harness connector.
Checking voltage
-
Switch the ignition on.
-
Using a multimeter, measure voltage supply between connector terminals 1 to 3 for voltage.
Specified value: approx. 5 V.
If the specified value was not obtained:
-
Check the wiring for a short circuit to each other, Battery positive, Ground or high resistance.
-
Check the wiring connections for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the specified value was obtained:
-
Using a multimeter, measure voltage supply between connector terminals 4 to 5 for voltage.
Specified value: near 4.35 V.
If the specified value was not obtained:
-
Check the wiring for a short circuit to each other, Battery positive, Ground or high resistance.
-
Check the wiring connections for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the specified value was obtained:
-
Using a multimeter, measure voltage supply between connector terminals 2 to 3 for voltage.
