“EPS” Warning Light Does Not Come ON with Ignition Switch Turned ON before Engine StartsS7RS0B6304010
Wiring Diagram
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.

“EPS” Warning Light Remains ON Steady after Engine StartsS7RS0B6304011
Wiring Diagram
Refer to ““EPS” Warning Light Does Not Come ON with Ignition Switch Turned ON before Engine Starts”.
Circuit Description
Operation (ON/OFF) of “EPS” warning light is controlled by P/S c ontrol module through combination meter.
If the P/S system is in good condition, P/S control module tu rns “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 4 1) Check for proper connection to the combination meter at
“G28-25” terminal and P/S control module at “E52-5”
terminal.
2) Measure resistance between the combination meter at “G28-25” terminal and the P/S control module at “E52-5”
terminal.
Is it infinite (
∞)? “EPS warning light
circuit” is open.
Go to Step 5.
5 1) Connect combination meter connector (“G28”) with ignition switch turned OFF.
2) Check for voltage between “E52-5” (“GRY” wire) terminal and body ground with ignition switch ON.
Is it 10 – 14 V? Replace the P/S control
module.
Replace the
combination meter.
Step
Action YesNo
Step Action YesNo
1 1) Check DTC referring to “DTC Check”.
Is there any DTC(s) (NO CODES on SUZUKI scan tool)? Go to applicable DTC
diag. flow.
Go to Step 2.
2 1) With ignition switch OFF, disconnect P/S control module connector (“E52”).
2) Check for proper connection to the P/S control module at “E52-5” terminal.
3) If OK, then turn ignition switch to ON position.
Does “EPS” warning light turn on? Go to Step 3.
Replace the P/S control
module.
3 1) With ignition switch turned OFF, remove combination meter and its connector.
2) Check for proper terminal connection to combination meter connector.
3) If connections are OK, ch eck that “EPS warning light
circuit” is as following.
• Insulation resistance of “EPS warning light circuit” wire is infinity between its terminal and each terminal
at combination meter connector.
• Wiring resistance of “EPS wa rning light circuit” wire is
less than 1 Ω.
• Insulation resistance of “EPS warning light circuit” wire is infinity between its terminal and vehicle body
ground.
Is circuit in good condition? Replace the
combination meter.
Repair EPS warning
light circuit.
