  4. If connections are OK, check the following points.
    • Resistance of "A1" and "C1" circuits: less than 1 Ω
    • Resistance of "A1" circuit between "C142" connector and ground: infinity
    • Resistance between "A1" circuit terminal and each terminal at "C142" connector: infinity
    • Voltage of "A1" and "C1" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON")

Are they in good condition? 		 Go to Step 3. Repair or replace defective wire harness.
3  Primary pressure sensor check
