IGNITION COIL CHECK M1163001200380
Check by the following procedure, and replace the coil if there
is a malfunction.
.
PRIMARY COIL AND IGNITION POWER
TRANSISTOR CONTINUITY CHECK
NOTE: No test can be performed on the Primary side of coil.
.
SECONDARY COIL CHECK
NOTE: It is impossible to check the secondary coil through the
continuity check as a diode is integrated in the secondary coil
circuit of this ignition coil. Accordingly, check the secondary coil
in the following procedure.
1. Disconnect the ignition coil connector.
2. Remove the ignition coil and install a new spark plug to the
ignition coil.
3. Connect the ignition coil connector.
4. Disable vehicle fuel pump by removing fuel pump relay or
disconnecting fuel pump connector D-18 (under rear seat).
5. Ground the side electrode of the spark plug and crank the
engine.
6. Check that spark is produced between the electrodes of the
spark plug.
7. If no spark is produced, replace the ignition coil with a new
one and recheck.
8. If spark is produced with the new ignition coil, replace the
old one as it is faulty. If no spark is produced again, the
ignition circuit is suspected as faulty. Check the ignition
circuit.
