Code 14, Ignition Signal Circuit, No Signal: Notes
ECM sends voltage signal to the igniter through ECM terminal "IGF". If this signal is not present 4 consecutive times during cranking, Code 14 will set. ECM uses this signal to pulse the fuel injector.
NOTE:
Test numbers refer to test numbers on diagnostic chart.
- Verifies voltage from ignition coil.
- Checks voltage from ECM.
- Checks for open in Black wire between ignition coil and igniter.
- Checks for power to ignition coil or for a faulty ignition coil.
- Checks for an open or short to ground in Black/Yellow wire or for faulty ECM.
