4. Ignition ON, verify that a test lamp illuminates between ignition voltage circuit terminal D and ground.
瀚慖f the test lamp does not illuminate, test the ignition voltage circuit for a short to ground or an open/high resistance. If the circuit tests
normal and the ignition voltage circuit fuse is open, test all the components connected to the ignition voltage circuit and replace as
necessary.
5. Engine running, observe the Ignition Coil 1-6 Control Circuit Low Voltage Test Status on the scan tool. Test Status should be Ok or Not
Run.
瀚慖f test status is Malfunction test for open or short to ground.
6. Engine running, observe the Ignition Coil 1-6 Control Circuit Open Test Status on the scan tool. Test Status should be Ok or Not Run.
瀚慖f test status is Malfunction test for open circuit.
7. Engine running, observe the Ignition Coil 1-6 Control Circuit High Voltage Test Status on the scan tool. Test Status should be Ok or Not
Run.
瀚慖f test status is Malfunction test for short to voltage.
8. If all circuits test normal, test or replace the appropriate T8 ignition coil.
