STEP 4. Measure voltage at C-215 fuel pump
relay (1) connector.

œ

Remove relay, and measure at junction block
side.

œ

Ignition switch: ON

œ

Voltage between terminal No. 3 and earth.

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 6 .

NO :

Go to Step 5 .

STEP 5. Connector check: C-303 ignition switch
connector

Q: Is the check result normal?

YES :

Check intermediate connector C-203, and

repair if necessary. If intermediate
connector is normal, check and repair
harness between C-215 (terminal No. 3)
fuel pump relay (1) connector and C-303
(terminal No. 2) ignition switch connector.

œ

Check power supply line for open
circuit and damage.

NO :

Repair.

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 9 .

NO :

Go to Step 8 .

STEP 8. Connector check: C-303 ignition switch
connector

Q: Is the check result normal?

YES :

Check intermediate connector C-203, and

repair if necessary. If intermediate
connector is normal, check and repair
harness between C-303 (terminal No. 2)
ignition switch connector and C-213
(terminal No. 3) fuel pump relay (2)
connector.

œ

Check power supply line for
open/short circuit.

NO :

Repair.

STEP 9. Connector check: C-134 engine-ECU
connector

Q: Is the check result normal?

YES :

Go to Step 10 .

NO :

Repair.

STEP 10. Measure voltage at C-134 engine-ECU
connector.

œ

Disconnect connector, and measure at harness
side.

œ

Ignition switch: ON

œ

Voltage between terminal No. 22 and earth.

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 11 .

NO :

Check intermediate connectors C-106 and

C-205, and repair if necessary. If
intermediate connectors are normal, check
and repair harness between C-213 (terminal
No. 2) fuel pump relay (2) connector and C-
134 (terminal No. 22) engine-ECU
connector.

œ

Check earthing line for open/short
circuit.
