5) If OK, then check the continuity between each terminal and
ground.
 Injector continuity: ∞ Ω (Infinity)

 Tester knob indication: Resistance (Ω)
Are the resistance and continuity OK?
YES Go to Step 2.
NO Replace the injector with a new one. (5-23)
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.
 Injector voltage: Battery voltage
NOTE:
Injector voltage can be detected only 3 seconds after ignition
switch is turned ON.
