4.
Measure the resistance in each primary coil, referring to specification.(To Coil Side)
1)
Specification : Approx. 0.74 ± 0.07Ω at 20℃(68℉)
a.
No.1 & 4 cyl. : terminals 3 & 2
b.
No.2 & 5 cyl. : terminals 3 & 1
c.
No.3 & 6 cyl. : terminals 3 & 4
Ignition "OFF"
Ignition coil connector : Disconnect
Visually/physically inspect the following items:
- Damage, cracks and flashover
Measure the resistance in each primary coil, referring to specification.(To Coil Side)
Specification : Approx. 0.74 ± 0.07Ω at 20℃(68℉)
No.1 & 4 cyl. : terminals 3 & 2
No.2 & 5 cyl. : terminals 3 & 1
No.3 & 6 cyl. : terminals 3 & 4
Measure the secondary coil resistance.
- Measure the resistance between the high-voltage terminal for the No. 3 and No. 6 cylinders, between the high-voltage terminals for the No. 1 and No. 4 cylinders and between the high-voltage terminals for the No.2 and No.5 cylinders.
Be sure, when measuring the resistance of the secondary coil, to disconnect the connector of the ignition coil.
Specification : Approx. 13.3 ± 1.9 (kΩ) at 20℃(68℉)
Is resistance within specified value?
YES
Thoroughly check connectors for loose or poor connections, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure
NO
Test with a new ignition coil and check for proper operation. If problem is corrected, replace ignition coil and go to "Verification of Vehicle Repair" procedure
