if you check the EV100 troubleshooting guide on this code you will see there are many things that can trigger this code. Here is what it says as possible causes:

POSSIBLE CAUSE
Defective 2 REC circuit.
* Check that 2 REC will gate on.
* Check for open circuit or loose connection
between 2 REC gate and PZ10 (white/red wire).
* Check for open circuit or loose connection
1 REC and 1 C through the 2 REC circuit.
Defective 5 REC circuit.
* Check for shorted 5 REC.
* Check for shorted 5 REC snubber (25 REC)
Open Choke (1X).
* Check for open circuit between T5 and T3.
Ohm meter should read zero ohms.
F or R contactor or power tips bouncing open.
* Check that power tips on F and R contactor
power tips do not bounce open during operation
(ie: travel over speed bumps or dock plates).

Now if you want the complete manual on this you can always go to flight systems website and get it.

What i usually find in most cases with these codes is a bad rec, it HAS TO be checked with a tester that can gate and preferrably load tested using a leak test like the handyman tester can do.
Using a VOM test or just pulling off gate wires is not definitive enough imo. It is easy to let one component throw you a curve on these panels and lead you around in circles, you usually wind up testing ALL the related components to find the culprit causing the issue.
