“EPS” Warning Lamp Does Not Come ON at Ignition Switch ON but Engine Stop
S4RS0A6304013
Wiring Diagram
Circuit Description
Operation (ON/OFF) of “EPS” warning lamp is controlled by P/S control module through combination meter.
If the P/S system is in good condition, P/S control module turns “EPS” warning lamp ON at the ignition switch ON, and
then turns it OFF at the engine start. If an abnormality in the system is detected, “EPS” warning lamp is turned ON
continuously by P/S control module. If P/S control module is disconnected, “EPS” warning lamp is not turned ON.
