measuring voltage and resistance.
CAUTION!
Keyless start control module cannot be checked by itself. It is strictly prohibited to connect voltmeter
or ohmmeter to keyless start control module with coupler disconnected from it.

Voltage Check
1) Disconnect negative (–) cable at battery.
2) Remove keyless start control module from vehicle body referring to “Keyless Start Control Module Removal and
Installation”.
3) Connect connector to keyless start control module.
4) Check voltage at each terminal number of couplers connected.
