- If connections are OK, check the following points.
- Resistance of "A1" and "A2" 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 "A2" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON")
