Self-Diagnostic System: Notes

The self-diagnostic system is used for diagnosing malfunctions of Electronic Concentrated Control System (ECCS) sensors and actuators. The Electronic Control Unit (ECU) has 2 available diagnostic modes. Before entering self-diagnostics, perform BASIC TESTING . This eliminates wasted diagnostic time and invalid diagnostic results.

NOTE: When performing BASIC TESTING , be careful not to erase any diagnostic information stored in ECU memory.
