Use this procedure to troubleshoot the Cat Data Link if a problem is suspected with the wiring. Use this procedure if any one of the diagnostic codes in Table 1 is active or easily repeated.
Table 1
Diagnostic Codes Table
Description Conditions which Generate this Code System Response
MID 0036 - CID 0296 - FMI 09 Unable to communicate with Transmission ECM The engine's Electronic Control Module (ECM) detects a failure in the Cat Data Link. The ECM detects a loss of communication with the transmission ECM. The code is logged.
MID 0036 - CID 0800 - FMI 09 Unable to communicate with VIMS The ECM detects a failure in the Cat Data Link. The VIMS main module has failed. The Cat Data Link is used for communication between electronic modules. The Cat Data Link is used to communicate information from the Electronic Control Module (ECM) to other electronic systems. The Cat Data Link is used for programming and troubleshooting the ECM.The ECM communicates with Caterpillar Electronic Technician (ET) in order to share status information and diagnostic information. Cat ET can also be used to configure the ECM parameters. This information will not be available if communication fails between the ECM and Cat ET.The ECM communicates with other controls in order to communicate the engine's operating status. The ECM communicates with the power train in order to perform machine functions. The following control modules may be used in your application: Engine ECM, VIMS Module, RAC Module and Transmission Control.

P1 ECM connector
(P1-8) Cat Data Link +
(P1-9) Cat Data Link − Test Step 1. Inspect the Electrical Connectors and the Wiring
Remove power from the ECM.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the connectors to other modules on the Cat Data Link. Refer to the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
Check the ECM connector (allen head screw) for the proper torque. Refer to Troubleshooting, "Inspecting Electrical Connectors" for details.
Check the harness and the wiring for abrasion and for pinch points. Expected Result:All of the connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - The harness and connectors appear to be OK. Proceed to Test Step 2.
Not OK - The connectors and/or wiring are not OK.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Shorts in the Harness
Disconnect ECM connector J1/P1 at the engine ECM.
Disconnect all control modules from the Cat Data Link.
Disconnect Cat ET from the service tool connector.
Measure the resistance from P1-8 to every terminal on
