9-18 ELECTRICAL SYSTEM
Step 2
1) Measure the battery voltage between input lead wires (O/W and B/W) at the ECM with the ignition switch
in the “ON” position.
Is the voltage OK?
Step 3
1) Measure the ignition coil primary peak voltage. (
!
9-19)
NOTE:
This inspection method is applicable only with the multi-circuit tester and the peak volt adaptor.
Is the peak voltage OK?
Step 4
1) Inspect the spark plug. (
!
2-10)
Is the spark plug OK?
Step 5
1) Inspect the ignition coil. (
!
9-19)
Is the ignition coil OK?
Step 6
1) Measure the CKP sensor peak voltage and its resistance. (
!
9-20 and 9-21)
NOTE:
The CKP sensor peak voltage inspection is applicable only with the multi-circuit tester and peak volt adaptor.
Is the peak voltage and resistance OK?
YES
Go to Step 3.
NO
• Faulty ignition switch.
• Faulty engine stop switch.
• Broken wire harness or poor connection of related circuit couplers.
YES
Go to Step 4.
NO
Go to Step 5.
YES
Go to Step 5.
NO
Faulty spark plug.
YES
Go to Step 6.
NO
• Poor connection of the ignition coil.
• Faulty ignition coil.
YES
• Faulty ECM.
• Poor connection of ignition couplers.
• Open circuit in wiring harness.
NO
Faulty CKP sensor.
