EPS Diagnosis General Description
S4RS0A6301003
The P/S system in this vehicle is controlled by the P/S
control module. The P/S control module has an on-board
diagnostic system which detects a malfunction in this
system. When diagnosing troubles, be sure to have full
understanding of the outline of “On-Board Diagnostic
System Description: ” and each item in “Precautions in
Diagnosing Troubles: ”, and then execute diagnosis
according to “EPS System Check: ”.
On-Board Diagnostic System Description
S4RS0A6301004
The P/S control module performs the on-board diagnosis
(self-diagnosis) on the system and operates the “EPS”
warning lamp (1) as follows.
• The “EPS” warning lamp lights when the ignition
switch is turned to ON position (but the engine at stop)
regardless of the condition of the P/S control system.
This is only to check if the “EPS” warning lamp is
operated properly.
• If the areas monitored by the P/S control module is
free from any trouble after the engine start (while
engine is running), the “EPS” warning lamp turns OFF.
• When the P/S control module detects a trouble which
has occurred in the monitored areas the “EPS”
warning lamp flashes ON and OFF while the engine is
running to warn the driver of such occurrence of the
trouble and at the same time it stores the exact
trouble area in memory inside of the P/S control
module.
Driving Cycle
A “Driving Cycle” consists of engine startup and engine
shutoff.
3 Driving Cycles Detection Logic
The malfunction detected in the first and second driving
cycle is stored in P/S control module memory (in the
form of pending DTC) but the “EPS” warning lamp does
not light at these time. It lights up at the third detection of
same malfunction also in the next driving cycle.
