Inspection of Rain / Light Sensor and Its Circuit (If Equipped)

Voltage and Signal Check

1) Remove harness cover. Rear View Mirror Removal and Installation
2) Check voltage using circuit tester and oscilloscope function of SUZUKI scan tool.

NOTE:

- Confirm that battery voltage is 11 V or more.
- An "ignition mode" in the following table represents a power supply mode available with the keyless push start system. For more details, refer to Description of Keyless Engine Start Function Description of Keyless Engine Start Function.
- Outputs from terminals marked with asterisk (*) cannot be measured with voltmeter because they are pulse signals. Use oscilloscope for its check if necessary.
