I removed LCC9 and LCC10 connectors, to read the harness resistance. Everything is ok, pins 1-3 are open and pins 2-4 shows 472 Ohms. The CLC LED is ON. I don't want to remove the CLC battery because the CLC data will be deleted.

I have doubt with the resistances because are old and overheated. The current CLC board was made in 1998.
