Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.

- Special tool
- (A): SUZUKI scan tool
- Turn ignition switch ON and confirm that MIL lights.
- Read DTC and freeze frame data according to instructions displayed on scan tool and print them or write them down.
Refer to scan tool operator's manual for further details.
If communication between scan tool and ECM is not possible, check if scan tool is communicable by connecting it to ECM in another vehicle. If communication is possible in this case, scan tool is in good condition. Then check data link connector and serial data line (circuit) in the vehicle with which communication was not possible.
- After completing the check, turn ignition switch off and disconnect scan tool from data link connector.
