CWBAD TKE traction

Getting a CWBAD red light on the CWIP board. No push buttons or key switches working on the COP. Also getting a SPI loop error. CWIP board is good, all wiring is landed correctly. Any other advice would be great. Thanks.

The problem is in the SPI loop. It could be a cable, the S24 card or any other board in the loop for job specific functions.
