Self-Diagnostic System Description: Description

The self-diagnostic system is used for diagnosing malfunctions of Electronic Concentrated Control System (ECCS) sensors and actuators. The Electronic Control Unit (ECU) has a number of available diagnostic modes within the computer.

Both models have 5 diagnostic modes. Before selecting any mode of self-diagnosis, always perform BASIC TESTING first. This will eliminate wasted diagnostic time and invalid diagnostic results.

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