(a) Turn the ignition switch to "OFF" position.
(b) Disconnect the ignition coil harness connector EN19 (EN20).
(c) Measure resistance between the ignition coil secondary
terminals.
Standard Resistance Value: 9.68-12.32 kΩ
Is the resistance specified value?
Replace the ignition coil. Refer to
No
2.10.8.3 Ignition Coil Replacement
(a) Turn the ignition switch to "OFF" position.
(b) Disconnect ECM harness connector EN01.
(c) Disconnect the ignition coil harness connector EN19 (EN20).
(d) Measure resistance between ECM harness connector EN01
terminal No.3(7) and the ignition coil harness connector
EN19 (EN20) terminal No.2 with a multimeter.
(e) Measure resistance between the ignition coil harness
connector EN19 (EN20) terminal No.2 and a reliable ground
with a multimeter. Check whether there is short to ground
circuit.
(f) Measure voltage between the ignition coil harness connector
EN19 (EN20) terminal No.2 and a reliable ground with a
multimeter. Check whether there is short to power supply
circuit.
