Hello.
If you follow the FSM trouble shooting guide to Diagnosis for "No Condenser fan no magnetic clutch operation" on page U-12 and have a failure at STEP 4 it tells you to Check ECU operation.
If you would like to save $100 and not buy a spare ECU pop that boy out and the most likely culprit is Resistor R842 which is the first component from the 1J pin.
The other lead in resistor is from the 1Q pin is R505 but is connected to the AC switch so that should blow up first it is a film 666Ω if you did manage to blow it.
I had the R842 resistor blown in 2 of the ECU's I have. On a non-blown one I measured the value at 4.1Ω and pulled the part number to confirm that value and determine its wattage rating.
The only visible number on the part I can make out is
3R9J
There are two major resistors with that code
RS-1-3R9J and RS-2-3R9J
They are Metal Oxide resistors rated at 3.9Ω and a 5% tolerance.
The different number there is the wattage. The other physically similar resistors are 1w.The 2w labeled resistors are about double the size. I would not recommended over watting these as this resistor is protecting an IC down the line if I pathed it proper.
Any 1 watt Metal Oxide resistor rated at 3.9-4Ω and a 5% tolerance should work fine. As I can only find those verbatim ones for sale in bulk. And do not need 50 of them.
