Schematic of the Cat Data Link
Note: The diagram above is a simplified schematic of the Implement ECM 1 and the Cat Data Link connections. The schematic is electrically correct. However, not all of the possible harness connectors are shown. Refer to the latest revision of Electrical Schematic, UENR6467 for the complete schematic.Implement ECM 2
The following is a list of Diagnostic Trouble Codes (DTCs) that are associated with the Cat data link of the machine.
Table 5
Implement (Steering) ECM 2 (MID 145)
DTC Code Description System Response
248-9 Cat Data Link: Abnormal Update Rate A Warning Level 2 Will Be Generated.
296-9 Transmission Control: Abnormal Update Rate A Warning Level 3 Will Be Generated.
296-12 Transmission Control: Bad Device or component A Warning Level 3 Will Be Generated.
E192 Steering System Malfunction event code will be activated.
Audible alarm will sound and fault indicator will flash.
296-14 Transmission Control: Special Instruction A Warning Level 2 Will Be Generated.
590-9 Engine Control Module: Abnormal Update Rate A Warning Level 3 Will Be Generated.
590-14 Engine Control Module: Special Instruction A Warning Level 2 Will Be Generated.
596-9 Implement Control Module: Abnormal Update Rate A Warning Level 2 Will Be Generated.
596-14 Implement Control Module: Special Instruction A Warning Level 2 Will Be Generated.
2466-9 Engine Aftertreatment Control #1: Abnormal Update Rate A Warning Level 1 Will Be Generated.
2466-14 Engine Aftertreatment Control #1: Special Instruction A Warning Level 1 Will Be Generated. Possible causes for an FMI 9 diagnostic code are:
A fuse for one of the ECM modules may have failed.
The wrong software is installed on an ECM.
An improper key was used.
The ECM is operating intermittently.
An open or a poor connection in the data link circuit.
There is a short in the data link circuit.
An ECM or smart device is not powering up or powering down properly.
Excessive noise on the data link circuit.
One of the ECMs or smart devices has failed. This condition is unlikely.Possible causes for an FMI 12 diagnostic code are:
A fuse for one of the ECM modules may have failed.
Incorrect transmission software is installed.
Incorrect machine application software is installed.Possible causes for an FMI 14 diagnostic code are:
The software is incorrect or incompatible for one of the modules within the data link.
The machine harness has failed.
A new ECM has been installed that is not the correct part.
One of the ECM modules in the data link has failed.

Note: Prior to beginning this procedure, inspect the harness connectors that are involved in this circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure, and in good condition. Check the wiring for pinch points or abrasions. Look for and repair areas that indicate wires
