5 Check For Power Feed to Coil Primary Control Circuits

1. With diagnostic read-out tool connected, put system in ``Actuate Coil 1,'' select ``Voltage Sensors Battery Voltage,''then push volt/ohm button to read voltage.
2. Touch diagnostic read-out tool volt probe to coil positive terminal.
3. If voltmeter does not read battery voltage, locate and repair open circuit in gray/black wire of coil to harness splice, then proceed to Test 16.
4. If voltmeter reads battery voltage, turn ignition switch Off and disconnect black/gray wire from coil negative terminal.
5. Turn ignition switch On, then put diagnostic read-out tool into actuate ``Ign Coil'' and voltmeter mode.
6. Touch voltmeter probe to coil negative terminal.
7. If voltmeter does not read above 10 volts, replace ignition coil, then proceed to Test 16.
8. If voltmeter reads above 10 volts, select ``Stop All Tests'' on diagnostic read-out tool and go into voltmeter mode.
9. Touch voltmeter probe to loose black/gray wire near ignition coil.
10. If voltage is above 9.8 volts, replace ignition coil proceed to Test 16.
11. If voltage is below 9.8 volts, turn ignition switch Off, then disconnect 14-way connector from SMEC.
12. Inspect 14-way connector for damaged terminals, then put diagnostic read-out tool in ohmmeter mode.
13. Touch ohmmeter probe to terminal No. 12 of 14-way connector. If ohmmeter shows continuity, locate and repair short to ground in J5 black/gray wire.
14. If ohmmeter does not show continuity, connect a jumper wire between black/gray wire near coil and ground.
15. Touch probe to terminal No. 12 of 14-way connector, if ohmmeter shows continuity, replace SMEC and proceed to Test 16.
16. If ohmmeter does not show continuity, locate and repair open circuit in J5 black/gray wire between coil and 14-way connector, then proceed to Test 16.
