ROLLER GP-TRACK-DOUBLE FLANGE 3097678 - Caterpillar

System Operation Description: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 the Caterpillar Monitoring System. The CAT Data Link is used for programming and troubleshooting the ECM.The ECM communicates with the Caterpillar Monitoring System in order to share engine information. The ECM communicates with the Caterpillar Electronic Technician (ET) in order to share status information. The ECM communicates with the Cat ET in order to share diagnostic information. The Cat ET can also be used to configure the ECM parameters on the engine. This information will not be available if communications fail between the ECM and the Cat ET.The 3512B engine can be FLASH downloaded over the CAT Data Link.

Test Step 1. Check for Connector Damage.
Turn the battery circuit breaker to the OFF position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Perform the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors".
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 of 6.0 N m (55 lb in).
Check the customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 lb in).
Check the harness and the wiring for abrasion and pinch points.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted, and the harness and wiring should be free of corrosion, abrasion or pinch points.Results:
OK - The connectors and wiring are okay. Proceed to test step 2.
Not OK - The connectors and/or wiring are not okay.Repair: Repair the connector and/or wiring or replace the connector and/or wiring. Stop.Test Step 2. Check the CAT Data Link.
Connect the Cat ET to the service tool connector J60.
Turn the battery circuit breaker to the ON position.
Check for any LOGGED diagnostic codes.
Start the engine and read the status information on the Cat ET.
Observe the engine oil pressure and the coolant temperature on the Cat ET.Note: If some of the parameters, but not all of the parameters were displayed, the CAT Data Link is okay. Check the component that is associated with any missing parameter.
Stop the engine.Expected Result:The Cat ET should display the Status Information.Results:
OK - The CAT Data Link is operating correctly at this time.Repair: Check the system for any diagnostic codes. Stop.
No Parameter Displayed. - There is a problem with the CAT Data Link. Proceed to test step 4.
Service Tool Did Not Power Up. - The Cat ET or the Communication Adapter did not power up. Proceed to test step 3.Test Step 3. Check the Power Supply Voltage.
Turn the battery circuit breaker to the OFF position.
Disconnect the Cat ET from the service tool connector J60.
Turn the battery circuit breaker to the ON position.
Measure the voltage between pin A and pin B at J60.
Turn the battery circuit breaker to the OFF position.
Reconnect Cat ET to the service tool connector
