Self Diagnosis System

A self diagnosis system is incorporated into all TCCS Electronic Control Units (ECUs) and into some Conventional EFI system ECUs. A Conventional EFI engine equipped with self diagnostics is a P7/EFI system. This diagnostic system uses a check engine warning lamp in the combination meter which is capable of warning the driver when specific faults are detected in the engine control system. The check engine light is also capable of flashing a series of diagnosis codes to assist the technician in troubleshooting these faults.
