n1: Check Continuity of IDM Circuit
Steps _Key Off, wait 10 seconds
_Disconnect E-Core ignition coil
_Disconnect processor 60 pin connector. Inspect for damaged pins, corrosion, loose wires, etc. Service as necessary
_Install breakout box, leave processor disconnected
_DVOM on 200,000 ohm scale
_Measure resistance between Test Pin 4 at the breakout box and ignition coil harness connector negative terminal
Result Is resistance between 20,000 and 24,000 ohms?
Direction YES

Remove breakout box. Reconnect processor. Service open circuit. Rerun Quick Test. Reconnect E-Core ignition coil

Notes It is important to know that the IDM circuit has a 20,000 ohm resistor between Test Pin 4 and Ignition Coil Negative Terminal
