Power Output Circuit Inspection

Check for open in harness.
1. Ignition "OFF".
2. Disconnect IG failure sensor connector and ignition coil connectors.
3. Measure resistance between terminal "2" of IG failure sensor harness connector and "3" of each ignition coil harness connector.
  Specification: Approx. below 1Ω

4. Is the measured resistance within specifications?
  YES
  - Go to "SIGNAL CIRCUIT INSPECTION " procedure.
  NO
  - Check open in harness between IG failure sensor and Ignition coil.
  - Repair or replace as necessary and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
