Yes
Step 4
Measure the ignition coil secondary resistance.
(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
Replace the ignition coil.
Yes
Step 5
Check the ignition coil control circuit.

Ignition Coil Harness Connector EO19
ECM Harness Connector EO01
FE02-9105b
(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.
Test Items
Standard Value
EO01 (1)-EO19 (A) / EO01 (17)-EO19
(C) Resistance
0 Ω
Resistance Between EO19 (A, C) and
A Reliable Ground
10 kΩ or higher
Voltage Between EO19 (A, C) and A
Reliable Ground
0 V
All normal?
No
Repair the circuit fault.
Yes
Note
Each time the ignition switch can not stay at the "ST" position longer than 5 s, otherwise it will damage the starter motor.
