Parking Assist Control Module: Testing and Inspection

Inspection of Parking Sensor System Control Module and Its Circuit (If Equipped)

Voltage and Signal Check

1) Remove parking sensor system control module (with connectors connected).
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 measuring these outputs.
