Diagnostic Modes
Self-diagnostic system can detect ECCS malfunctions and store related trouble codes. Trouble codes, including intermittent codes, are stored in ECU memory and are available for interpretation unless codes have been cleared.
Self-diagnostic system uses single or dual Light Emitting Diodes (LEDs), located on ECU. For system application, see SELF-DIAGNOSTIC SYSTEM table. For ECU location, see ECU LOCATION table.
