Complex failures
Disconnect the cable from the solenoid and test the
solenoid with a testing apparatus to detect a break. So-
lenoid resistance shall be 2...4 Ohm. In case the sole-
noid failure is not detected check the solenoid control
cable for mechanical damage, and check the wire with
the testing apparatus to detect if there is a break be-
tween the solenoid socket terminal and the terminal 2
of 25-pole socket of the electronic unit (Figures 6.13.1,
6.13.2, 6.13.3).
Disconnect the cable from the solenoid and test the
solenoid with a testing apparatus to detect a break. So-
lenoid resistance shall be 2...4 Ohm. In case the sole-
noid failure is not detected check the solenoid control
cable for mechanical damage, and check the wire with
the testing apparatus to detect if there is a break be-
tween the solenoid socket terminal and the terminal 14
of 25-pole socket of the electronic unit (Figures 6.13.1,
6.13.2, 6.13.3).
Disconnect the cable from the solenoid and test the
solenoid with a testing apparatus to detect a short cir-
cuit. Solenoid resistance shall be 2...4 Ohm. Or meas-
ure the solenoid useful current applying the current of
6 V. The current shall not exceed 3.2A. Disconnect the
socket from the electronic unit, check the terminals 2
and 14 for a short circuit (the solenoids shall be dis-
connected during this procedure) (Figures 6.13.1,
6.13.2, 6.13.3).
Check the remote control buttons cables for mechani-
cal damage by lift of RLL. Disable each button for lift
one-by-one until the failure is gone. Stop the engine
when you disable the buttons. If the failure is still not
eliminated, disconnect the socket from the electronic
unit and ring out the terminals 10 and 12 for a short
circuit by testing apparatus (Figures 6.13.1, 6.13.2,
6.13.3).
Check the remote control buttons cables for mechani-
cal damage by lift of RLL. Disable each button for lift
one-by-one until the failure is gone. Stop the engine
lowering 5
when you disable the buttons. If the failure is still not
eliminated, disconnect the socket from the electronic
unit and ring out the terminals 20 and 12 for a short
circuit by testing apparatus (Figures 6.13.1, 6.13.2,
6.13.3).
