Schematic For CAT Data Link Note: When a CCM is connected to a single genset, "B+" is connected directly from TS1-17. When a CCM is connected to multiple gensets the diode must be connected. Also, "B+" must be wired to TS1-15. | |
Note: CID 248 FMI 9 replaces the former CID 560 FMI 11 for a fault with the CAT data link.
The following conditions will cause a CID 248 FMI 9:
- There is a short from the wire that connects to contact "19" of the CAT data link to the battery ("B+").
- There is a short from the wire that connects to contact "20" of the CAT data link to the battery ("B+").
- There is a short from the wire that connects to contact "19" of the CAT data link to ground ("B-").
- There is a short from the wire that connects to contact "20" of the CAT data link to ground ("B-").
The GSC cannot detect an open in the circuit of the CAT data link. Troubleshoot the wiring and repair the wiring. See Testing And Adjusting, "Schematic and Wiring Diagrams".
The GSC treats a CID 248 as an alarm fault. Active alarm faults are shown on the display when the alarm codes key is pressed. Also, the ECS is in any position except the OFF/RESET position. Clear the fault from the fault log after troubleshooting is complete.
