FI SYSTEM DIAGNOSIS 4-755) If OK, then check the continuity between each terminal andground.1 Injector resistance: ∞ Ω (Infinity)Are the resistance and continuity OK?YES Go to Step 2.NO Replace the injector with a new one. (5-14)6) After repairing the trouble, clear the DTC using SDS tool.(4-26)Step 21) Turn the ignition switch to ON.2) Measure the injector voltage between Y/R wire and ground. Injector voltage: Battery voltage(+ Y/R – - Ground)NOTE:Injector voltage can be detected only 3 for seconds after ignitionswitch is turned ON. 09900-25008: Multi-circuit tester set Tester knob indication: Voltage ()Is the voltage OK?22VYESNO• Gr/W wire open or shorted to ground, or poor dconnection (#1 cylinder side)• Gr/B wire open or shorted to ground, or poor cconnection (#2 cylinder side)• Gr/Y wire open or shorted to ground, or poor bconnection (#3 cylinder side)• Gr/R wire open or shorted to ground, or poor aconnection (#4 cylinder side)• If wire and connection are OK, intermittent troubleor faulty ECM.• Recheck each terminal and wire harness foropen circuit and poor connection.• Replace the ECM with a known good one, andinspect it again.Open circuit in the Y/R wireECM couplers (Harness side)3) After repairing the trouble, clear the DTC using SDS tool.(4-26)
