TECHNICAL FEATURE
OBD (On-Board Diagnostic) SYSTEM
This vehicle complies with the emission limits of Euro 4 and OBD stage 1 regulation.
Existing PGM-FI system already equips the self-diagnostic system that detects the PGM-FI system malfunction, and that
malfunction data can be read by MCS (Motorcycle Communication System) as the DTCs or freeze data.
Based on existing PGM-FI diagnostic system, for OBD stage 1, following items are equipped with this vehicle.
– Additional self-diagnostic function for the fuel emission control
– MIL indication pattern for malfunction
– GST (General Scan Tool) connection to the vehicle
PGM-FI SELF-DIAGNOSTIC SYSTEM
In addition to existing self-diagnostic system, following function and DTC (Diagnostic Trouble Code) are prepared (page 4-46).
– EVAP purge control solenoid valve circuit
– PAIR control solenoid valve circuit
– Ignition Primary circuit
MIL INDICATION
In the existing PGM-FI system, if the PGM-FI system detects the malfunction at the present, the MIL blinks the number of trouble
code with idle engine speed.
But in this PGM-FI system for OBD, when the system detects the malfunction, it turns the MIL ON without blinking unless otherwise
the SCS circuit short (reading DTC with DLC connector).
