Hi Lee,
Those are not resistors, they are diodes.
Their purpose is to prevent high-voltage spikes from damaging the transistors.
When the transistor turns 'off', the magnetic field of the solenoid collapses.
This collapsing field generates a high voltage spike in the coil of the solenoid which can damage the transistor.
The diode 'short circuits' this voltage away from the transistor.

I've just had a text, you're still getting 'Hardware not Found'. Your cable passes the 'paperclip' test, so the fault is on the AXE401.
Post some pics here, showing power and solenoid connections, and someone will help.
Cheers,
Buzby
