Circuit Description
Operation (ON/OFF) of "EPS" warning light 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 light 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 light is turned ON
continuously by P/S control module. If P/S control module is disconnected, "EPS" warning light is not turned ON.
Troubleshooting
Step
1 1) Turn ignition switch ON.
Do the other warning lights come on?
2 1) Check power supply circuit and ground circuit for P/S
control module referring to "P/S Control Module Power
Supply and Ground Circuit Check".
Is check result in good condition?
3 1) Remove combination meter and disconnect combination
meter connector ("G28") with ignition switch turned OFF.
2) Check for proper connection to the combination meter at
"G28-31" terminal.
3) If OK, check voltage between "G28-31" ("RED/BLK"
wire) terminal and body ground with ignition switch ON.
Is it 10 – 14 V?
