260001055 — DCB fails to sense correct state of the RCIB fault lines
GE Healthcare CT error code, reported by the GE LightSpeed CT platform.
What 260001055 means
On LightSpeed QX/i and LightSpeed Plus CT systems, status code 260001055 indicates: DCB fails to sense correct state of the RCIB fault lines. The code originates in the DAS (Data Acquisition System) section of the GE LightSpeed CT platform. Severity level error (Error condition).
Reported action: Check the DCB's RCIB cabling before suspecting a board fault: verify the J4 signal cable and the bus terminator are seated on the correct DCB connectors (J4 vs J5) per the wiring diagram in the service manual — a swapped connection is the documented cause of this exact fault..
Reported by the OBC's HOP fault handler (hop_fault_test.c) on LightSpeed QX/i and Plus systems, typically on almost every power-up. The DCB sub-system cannot sense the correct state of one or more RCIB fault lines — the serial and parallel fault readback do not match the expected state — with the source noting the likely cause is that the RCIB is miswired on this node.
