Introduction to On Board Diagnostics (II)

Fundamentals of PowertrainControl strategies & OBD IIDiagnosticsIgnition Coil ( DTCs 350-379):379):Ignition coil diagnostics are performed for deterioration of ignition coilprimary/secondary characteristics. In case of ignition coil primary/secondary electricalcircuit malfunction, fault code 350 is assigned.In case of ignition coil A primary/secondary electrical circuit malfunction, fault code 351is assigned. Similarly for the case of ignition coil B to L primary/secondary electricalcircuit s' malfunction, fault codes 352-362 362 are assigned. If timing reference highresolution signal A has malfunction fault code 370 is assigned. If timing reference highresolution signal A has too many pulses fault code 371 is assigned.If timing reference high resolution signal A has too few pulses fault code 372 is assigned.If timing reference high resolution signal A has intermittent fault, ffault code 373 isassigned.If timing reference high resolution signal A has no pulses, fault t code 374 is assigned.If timing reference high resolution signal B has similar faults, fault codes 375-379379respectively are assigned.
