Trouble Diagnoses — Diagnostic Procedure 6: IGNITION SIGNAL (Code No. 21) & DETONATION SENSOR (Code No. 34)
EF & EC-90wiring diagramL = L.H. drive model; R = R.H. drive model; A = A/T model; M = M/T model. Connector and harness routing varies between LH and RH drive configurations. Power transistor unit connector references differ: LH/A/M uses F30, F10(Brown), F9(Gray), F8(White); RH uses E46, E108.
