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.
NOTE
• As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when
ignition switch is ON.
• Voltage with asterisk (*) cannot be measured by voltmeter because it is pulse signal.

Description
The keyless start control module detects DTC by using signals from the key reminder and driver side door request
switches. The keyless start control module makes the key indicator light in the combination meter flash on and off by
using CAN communication.
