Power off
-
Before switching off completely, the system switches to "power latch" mode.
During this phase, the system checks the operation of certain components that
cannot be tested during the operating phase.
To ensure that all the tests are performed correctly, power must be
maintained for at least 30 seconds after dashboard shutdown (wait 30 seconds
between turning off the engine: using switch (12) before cutting off the
general power supply with switch (1)).
Fault diagnosis
Symptom 1: When the system is powered up, the effort required to turn the wheel
does not reduce. Furthermore, the system does not "click".
Solutions:
 Ensure that the ignition switch is in the up position (on).
 Check that the wiring harness is connected to the battery and that the
battery is charged.
 Check all connections between the battery, EPS and ignition switch.
Ensure that there is no power loss and that they are connected to the
correct pins.
 Check that all fuses between the battery and the EPS are in working
order.
If the system is still malfunctioning after these checks, it must be immediately returned
to the Alpine after-sales service.
Symptom 2: When the steering wheel is turned, the power steering stops before
reaching full travel. When the wheel it turned in the opposite direction, however, the
power steering operates correctly to full travel.
Solution: This problem is due to the maximum rotation allowed by the system of
1600°. If the 0° position stored by the system is significantly different from the angle
of the wheels, the angle measured by the EPS may exceed the maximum value in one
direction. To solve this problem, disconnect the intermediate shaft and rotate the
wheel 360° in the direction of correct system operation. This will align the system's
0° position with that of the wheels.
Symptom 3: When driving the vehicle, the power steering varies randomly, even
though the system is constantly powered up.
Solution: Ensure that all connections between the EPS, the battery and the ignition
switch are shielded and sealed and that there is no corrosion or dirt on them.
If these solutions fail to solve the problem, the system must be immediately returned to
the Alpine after-sales service.
