General Operation
The control module self–diagnoses SSPS system. If there
is any malfunction, the warning lamp comes ON and at the
same time a trouble code is set. The trouble code can be
retrieved or cleared only by SCANTOOL.
In normal condition, If the ignition is turned on, the warning
lamp comes on for the first 2 sec and out. During this 2 sec,
the control module is diagnosing SSPS system, so a driver
can feel a little heavy steering effort.
If the warning lamp stays on after the 2 sec or comes on
afterward, it means there is a malfunction and a related
trouble code is recorded.
The warning lamp once come on does not go off even if the
malfunction is cleared. It goes off after ignition is turned off
and on without a malfunction.However the trouble code still remains in the control mod-
ule.
