4-78 FI SYSTEM DIAGNOSIS
5) If OK, then check the continuity between each terminal and
ground.
Injector continuity: ∞ Ω (Infinity)
09900-25008: Multi-circuit tester set
Tester knob indication: Resistance (Ω)
Are the resistance and continuity OK?
6) After repairing the trouble, clear the DTC using SDS tool.
(4-27)
Step 2
1) Turn the ignition switch ON.
2) Measure the injector voltage between Y/R wire and ground.
