Car generates a 2815 fault. During the cycle test it drops EES C and the DGR ((doorand gate)relay before allowing a run. The EES and C relays function fine and drop then repick as they should. The output CIO never toggles thus allowing DGR to stay picked.
I have been able to toggle the CIO output via the tool. The relays are in good shape and we did try a different EES relay with the same results.

Sorry a quick correction.
The door gate relay is actually GDS.
This problem occurs on inspect as well as normal. The route mechanic did swap the LCMLB with a spare but the problem remained.

Do you know if this has the old mlb board..or has it been upgraded with the remote FUJI relays?

The problem turned out to be a faulty LCR contact. Another example of an error code leading one in the wrong direction.
