3.CHECK HARNESS AND CONNECTOR (PUSH START SWITCH - CERTIFICATION ECU [SMART KEY ECU ASSEMBLY])

Disconnect the G171 push start switch connector.

Disconnect the G170 certification ECU (smart key ECU assembly) connector.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
G171-5 (SWIL) - G170-20 (SWIL)	Always	Below 1 Ω
G171-3 (GND) - G170-30 (AGND)	Always	Below 1 Ω
G171-5 (SWIL) or G170-20 (SWIL) - Body ground	Always	10 kΩ or higher
G171-3 (GND) or G170-30 (AGND) - Body ground	Always	10 kΩ or higher

Result:

Proceed to
OK
NG
