Fuel Injector Circuit Check - Suzuki 2006 SX4 Service Manual

1A-196 Engine General Information and Diagnosis:
Step
11 Sensor power source circuit check
1) Connect connectors to ECM with ignition switch turned
OFF.
2) Turn ON ignition switch, measure each voltage between
"C01-14", "E01-35", "E01-34" and "C01-43" terminal of
ECM connector and vehicle body ground.
Is each voltage 4 – 6 V?
12 Sensor power source circuit check
1) Disconnect connectors from ECM, TP sensor, MAP
sensor, A/C refrigerant pressure sensor (if equipped with
A/C) and APP sensor with ignition switch turned OFF.
2) Measure each resistance between "C01-14", "E01-35",
"E01-34" and "C01-43" terminal of ECM connector and
vehicle body ground.
Is each resistance infinity?
