KIT-SEAL- 2430396 - Caterpillar

Illustration 1 g01816865This diagnostic code is recorded when the Transmission ECM receives information from the Chassis ECM and this information is NOT correct.Note: Each connector contact should withstand 45 N (10 lb) of pull. Each wire should remain in the connector body. This test checks whether the wire was properly crimped in the contact and whether the contact was properly inserted into the connector. Note: Other related diagnostic codes may cause this diagnostic code. Check for other related diagnostic codes.Test Step 1. VERIFY THE HARDWARE AND THE SOFTWARE PART NUMBERS.
Verify whether the following part numbers are correct:
Software part number for the Transmission ECM
Software part number for the monitoring systemNote: Consult the Business Unit that is producing the product for the correct configuration of the machine. Expected Result:All part numbers are correct.Results:
OK - All part numbers are correct. Proceed to Test Step 2.
NOT OK - All of the part number are NOT correct.Repair: One of the following modules may have the wrong part number and/or the software configuration is NOT correct: the Chassis ECM, the electronic engine control ECM, the Transmission ECM and the Brake/Cooling ECM. See Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program".STOPTest Step 2. INSPECT THE HARNESS CONNECTIONS.
Turn the key start switch and the disconnect switch to the OFF position.
Inspect the harness connections that are related to the Cat data link. Make sure that the connectors are clean and that the connectors are tight.
Check the mating of the connector.
Check the wires at the connector.
Check each wire for nicks and/or signs of abrasion in the insulation.
Check for moisture at the connector.
Check for dirty contacts and/or corroded contacts.
Check each pin and check each socket. Expected Result:The machine harness connectors are tight and free of corrosion.Results:
OK - The machine harness connectors are tight and the connectors are free of corrosion. Proceed to Test Step 3.
NOT - The machine harness connectors require repair.Repair: Repair the harness or replace the harness.STOPTest Step 3. CHECK FOR ADDITIONAL RELATED DIAGNOSTIC CODES.
Ensure that all electronic control modules that use the Cat data link are connected.
Turn the disconnect switch and the key start switch to the ON position.
Acknowledge any active diagnostic codes that are currently displayed on the message center.
Verify that NO related diagnostic codes are present. Expected Result:No other diagnostic codes are present.Results:
OK - No other diagnostic codes are present. Proceed to Test Step 4.
NOT OK - Other related diagnostic codes are present.Repair: Exit this procedure and perform the other related diagnostic codes. Verify that the other related diagnostic codes are NOT present. Observe the status of CID 1273 FMI 09 diagnostic code. If the CID 1273 FMI 09 diagnostic code remains active, perform the CID 1273 FMI 09 procedure again.STOPTest Step 4. CHECK FOR SHORTS TO GROUND.
Turn the disconnect switch and the key start switch to the OFF position.
Disconnect the machine harness from all electronic control modules that use the Cat data link.
At the machine harness for the Transmission ECM, measure the resistance between frame ground and the following data link
