If connections are OK, check the following points.
Resistance of "A1" and "A2" circuits: less than 1
Resistance of "A1" circuit between knock sensor connector and ground: infinity
Resistance between "A1" circuit terminal and other terminal at knock sensor connector: infinity
Voltage of "A1" and "A2" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON")
Are they in good condition?
YES
Go to Step 3.
NO
Repair or replace defective wire harness.
