>> INSPECTION END
1.CHECK IGNITION COIL WITH POWER TRANSISTOR-I
2.CHECK IGNITION COIL WITH POWER TRANSISTOR-II
CAUTION: Do the following procedure in the place where ventilation is good without the combustible.
NOTE: Do not use CONSULT to release fuel pressure, or fuel pressure applies again during the following procedure.
Spark should be generated.
CAUTION:
NOTE: When the gap is less than 13 mm (0.52 in), the spark might be generated even if the coil is malfunctioning.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace malfunctioning ignition coil with power transistor. Refer to EM, "Removal and Installation".
