Go to the +5 VDC (IOT) Wirenet and check the wires between
on the IOT LVPS and P/J418B8-6 on the IOT Drive PWB. Go to the DC
COM (IOT) Wirenet and check the wires between P/J21-5 on the IOT
LVPS and P/J418B-4 on the IOT Drive PWB.
Go to Flag 1 on BSD 9.11 and check the wire for a short circuit to ground. Go to
Flag 3 on BSD 9.11. Check the wires for an open circuit. If the wires are good,
replace the IBT Clean Blade Home Position Sensor
Replace the IOT Drive PWB (PL 9.2).
