So got replacement software chips (DK15) from TKE and installed them in a World Electronics CLC board that is supposed to be the equivalent of a BP4 board. Have comms with the Door Board & Selector board but no comms with CLC or Group. It is a 5-stop Duplex. Plugged into Power/Relay board and CLC board directly with no comms. WD LED is out on CLC board. Have 5.09 VDC on CLC board and 54.6 ohms on PSC to NSC with everything connected up. Believe it should be 55 ohms, so I think the 5VDC is good and the resistance check is good. FAST manual says if WD LED is not continuously lit, then CLC SW must be replaced. Checking to see if there are any other suggestions as I just got this SW from TKE. The M1 chip is soldered in, so I just replaced M2, M3 and M4. Also noticed in DMC 1 manual that if car is part of a group, the CLC and SW must be changed in all cars. So that may be what my issue is? No CLC comms or Group comms?
