Checking For Fuel Leaks

Using Diagnosis Check Wire (SST09843-18020), connect Data Link Connector 1 (DLC1) terminals +B and FP. Turn ignition on, with engine off. When fuel return hose is pinched (DO NOT bend hose, as it may cause cracking), fuel pressure within high pressure line will rise to approximately 57 psi (4 kg/cm² ). Pinch fuel return hose and verify there are no fuel system leaks. When inspection is completed, turn ignition off and remove diagnosis check wire from DLC1.
