(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect the ignition coil harness connector EO19.
(c)
Measure resistance between ignition coil secondary
terminals.
Standard Resistance Value: 8.86-10.82 kΩ
Is resistance normal?
No
(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect ECM harness connector EO01.
(c)
Disconnect the ignition coil harness connector EO19.
(d)
With a multimeter, measure resistance between ECM
harness connector EO01 terminal No.1 and ignition coil
harness connector EO19 terminal A, and resistance between
EO01 terminal No.17 and EO19 terminal C.
(e)
With a multimeter, measure resistance between ignition coil
harness connector EO19 terminal A, C and a reliable ground.
Check whether the circuit is short to ground.
(f)
With a multimeter, measure voltage between ignition coil
harness connector EO19 terminal A, C and a reliable ground.
Check whether the circuit is short to power supply.
