Q: Is the check result normal?

YES :

Go to Step 17.

NO :

Repair.

STEP 17. Check harness between battery and C-
215 (terminal No. 4) fuel pump relay (1)
connector.

NOTE: Before checking harness, check intermediate
connector C-202, and repair if necessary.

œ

Check power supply line for damage.

Q: Is the check result normal?
