Component Inspection
Check Ignition Coil
1.

IG KEY : OFF , Engine : OFF

2.

Disconnect ignition coil connectorC52/ C53.

3.

Measure the primary coil resistance.

- Connect the negative (-) terminal of a 3V power supply to terminal 2 of the power transistor; then check whether there is continuity between terminal 1 and terminal 2 when terminal 3 and the positive (+) terminal are connected and disconnected.

1)

[Specification]

a.

In case of connecting terminal 3 with the positive (+) terminal

Resistance between terminal 2 and 1: Approx. 0.78Ω±10%(20°C)

b.

In case of not connecting terminal 3 with the positive (+) terminal

Resistance between terminal 2 and 1: infinite(∞Ω)

4.

Measure the secondary coil resistance between the high-voltage terminals of the ignition coil.

1)

[Specification] Approx. 20kΩat 20°C(68°F)

5.

Is the ignition coil normal?

YES

a.

Ignition coil is OK.

b.

Possibility of defective ECM. Temporarily test with a new ECM and check for proper operation.

If problem is corrected, replace ECM and go to "Verification of Vehicle Repair" procedure.

NO

a.

Test with a new ignition coil and check for proper operation.If problem is corrected, replace it.

And go to "Verification of Vehicle Repair" procedure.
