IGT is ignitor gate drive.
IGF line is ECU read back, (called the spark monitor)
IGT is the ECU driving dwell and spark,
if IGT toggles and the monitor pin does not
that means the coil is open(ohm it yet)
or the ignitor is dead
if the IGT line is dead, the ECU is bad or CMP /CKP dead. (we are not getting DTC codes for CMP or CKP so they are not dead) this is why cranking for 5 full seconds is so important,
The Ignition coil was tested:
primary = 1.4 ohms
secondary = 13.46K ohms
- Below is a picture of igniter and noise suppressor from another Turbo Sprint car which has a running engine. We will double check that the Igniter chassis has a good ground, on the non running car later today. I wonder if a poor igniter ground can also cause code 41?
- Also attempted to sketch schematic showing igniter and noise suppressor guts. Guessing a bit on the igniter internals, as I was using bits of information posted on various Suzuki forums.
