4-76     FI SYSTEM DIAGNOSIS

“C41” (P0230-H/L) FP RELAY CIRCUIT MALFUNCTION

INSPECTION
Step 1 (When indicating C41:)

1) Turn the ignition switch to OFF.
2) Remove the seat tail cover. (

8-4)

3) Check the FP relay coupler for loose or poor contacts. 

If OK, then check the FP relay. (

5-6)

Is the FP relay OK?

DETECTED CONDITION

POSSIBLE CAUSE

C41

No voltage is applied to fuel pump 
although fuel pump relay is turned ON, 
or voltage is applied to fuel pump, 
although fuel pump relay is turned OFF.

• Fuel pump relay circuit open or short
• Fuel pump relay malfunction
• ECM malfunction

P0230

H

Voltage is applied to fuel pump although 
fuel pump relay is turned OFF.

• Fuel pump relay switch circuit shorted to power 

source

• Faulty fuel pump relay (switch side)

L

No voltage is applied to fuel pump 
although fuel pump relay is turned ON.

• Fuel pump relay coil circuit open or short

• Recheck each terminal and wire harness for 

open circuit and poor connection.

• Replace the ECM with a known good one, and 

inspect it again.

NO

Replace the FP relay with a new one.
