Check harness connector B-12X at MFI relay fordamage.Q: Is the harness connector in good condition?YES : Repair harness wire between MFI relay connector B-12X (terminal No. 4) and fuel pressure solenoidconnector B-101 (terminal No. 1) because of opencircuit or short circuit to ground. Then go to Step 12.NO : Repair or replace it. Refer to GROUP 00E, HarnessConnector Inspection P.00E-2. Then go to Step 12.CONNECTOR: C-121STEP 6. Measure the power supply voltage at ECMconnector C-121 by backprobing.(1) Do not disconnect connector C-121.(2) Turn the ignition switch to the "ON" position.HARNESSCONNECTOR:COMPONENT SIDE13 12 11 10 9 8 7 6 5 4 3 2 126 25 24 23 22 21 20 19 18 17 16 15 14C-121 (Y)AK203488AB1 2 3 4 5 6 7 8 9 10 11 12 1314 15 16 17 18 19 20 21 22 23 24 25 26C-121 HARNESSCONNECTOR:HARNESS SIDEAK203494AB(3) Measure the voltage between terminal No. 3 and ground bybackprobing.• Voltage should measure battery positive voltage.(4) Turn the ignition switch to the "LOCK" (OFF) position.Q: Is battery positive voltage (approximately 12 volts)present?YES : Go to Step 9.NO : Go to Step 7.CONNECTOR: C-121STEP 7. Check harness connector C-121 at ECM fordamage.Q: Is the harness connector in good condition?YES : Go to Step 8.NO : Repair or replace it. Refer to GROUP 00E, HarnessConnector Inspection P.00E-2.
