Precautions in Diagnosing Trouble

- Do not disconnect couplers from HVAC control module, battery cable from battery, HVAC control module ground wire harness from body or main fuse before confirming diagnostic information (diagnostic trouble code) stored in HVAC control module memory.
- Diagnostic information (diagnostic trouble code) stored in HVAC control module can be checked by reading the flashing pattern of the fresh air indicator lamp and recirculation air indicator lamp. Also, it can be checked by using SUZUKI scan tool. Before checking diagnostic information (diagnostic trouble code), read this manual and operator's manual for SUZUKI scan tool to know how to read diagnostic information (diagnostic trouble code).
- When checking diagnostic information (diagnostic trouble code) by reading the flashing pattern of the fresh air indicator lamp and recirculation air indicator lamp, keep in your mind that each diagnostic information (diagnostic trouble code) has priority. And, only diagnostic information (diagnostic trouble code) which has the highest priority is indicated. Therefore, after troubleshooting the malfunction, make sure if there exists any other diagnostic information (diagnostic trouble code).
- Be sure to read Precautions for Electrical Circuit Service before inspection.
