Did you ohm out the communications plug? On the board, it should be open from pins 1-3 and 460-480ohms pins 2-4. Does the LED on the CLC board come one and stay on?
Replacing the resistors is probably not gonna work as it's not fixing the underlying problem (what blew them?) and there's a good chance there's other damage.

Replace CLC. If you try and plug service tool directly into CLC with selector and door disconnected and no comms

Watchdog LED is ON. I have 5.1V between C48 and CLC Ground.
I can't stablish communication in any card (door operator , CLC and selector)
I have 2.3kOhm between PSC and physic ground. The same with NSC and physic ground. That data was taken with serial harness (LCC9 and LCC10) disconnected from CLC board, door operator and selector. The problem continues...

I have seen a few pins removed from the jack where you plug in the fast tool. Check that the pins didnt get pushed through or the wire removed to fool you.
I like elevators and cars. Be Smart Work Safe!
