Inspection (with KDS/GDS)
Electrical body system faults can be quickly diagnosed using the vehicle diagnostic system (KDS/GDS).
The diagnostic system (KDS/GDS) provides the following information.
Self-Diagnosis: Checks malfunction and Diagnostic Trouble Code (DTC)
Current Data: Check the system input/output status.
Actuation Test: Check the system operating status
Additional function: Control of other functions, including the setting parameter system and zero point adjustment.
Select "Vehicle Model" and "Body Control Module (BCM)" for inspection using the tester.
Select the "Current Data" menu to view the current input/output data status.

[Type without BCM]
Check the circuit continuity between the terminals in each switch position, as shown below.
