Diagnostic Circuit Check

CAUTION:
- A TECH-1 that displays faulty data should not be used, and the problem should be reported to the manufacturer. The use of a malfunctioning TECH-1 can result in misdiagnosis and unnecessary parts replacement.

The "Diagnostic Circuit Check" is an organized approach to identifying a problem created by an anti-lock brake system (ABS) malfunction. It must be the starting point for any ABS complaint diagnosis, because it directs the service technician to the next logical step in diagnosing the complaint.

The "Scan Data" listed in the table may be used after completing the "Diagnostic Circuit Check" and finding the on-board diagnostics functioning properly and diagnostic trouble codes (DTCs) displayed.

Only the parameters listed below are used in this manual for diagnosing. If a scan tool other than TECH-1 is used and reads other parameters, the values are not recommended by Suzuki Motor Corporation for use in diagnosing.
