KIT-SEAL 4799627 - Caterpillar

Illustration 1 g02684778This diagnostic code is recorded when the Advisor ECM does not receive expected information from the instrument cluster through the CAN Data Link for more than five seconds.System Response:This failure results in events that are logged against an ECM that cannot be explained directly. The Advisor ECM cannot communicate with the instrument cluster or the instrument cluster appears to communicate intermittently.Test Step 1. VERIFY THE HARDWARE AND THE SOFTWARE PART NUMBERS.
Verify that the following information is correct:
The part number of the Advisor ECM Onboard Software
The part number of the Advisor ECM Note: Consult your Caterpillar Dealership for the correct part numbers of the configuration software.Expected Result:All part numbers are correct. Results:
OK - All part numbers are correct. Proceed to Test Step 2.
NOT OK - All part numbers are NOT correct. Repair: The installed Advisor ECM has the wrong part number or the incorrect configuration software is installed. Replace the incorrect Advisor ECM with a module that has the correct part number. Flash the correct configuration software. See the Testing and Adjusting, "Module - Flash Program" section of this manual.STOPTest Step 2. INSPECT THE HARNESS CONNECTIONS
Turn the disconnect switch to the OFF position.
Inspect all harness connections that are related to the CAN Data Link. Make sure that the connectors are clean and tight.
Check the connectors for proper mating. Ensure that all the seals are present and in place.
Check the harness for signs of damage or abrasion.
Check the wires at the connector. Ensure that the wires are secured tightly into the connector. Take care not to pull the wire out of the connector.
Check the exposed wires at the connectors for nicks or signs of abrasion.
Check for moisture inside the connector.
Check the connectors for dirty contacts or corroded contacts.
Check each pin and each socket of the machine harness connectors. Ensure that the contacts are properly installed. The contacts should mate correctly when the two pieces of the connector are placed together. Expected Result:The machine harness connectors are tight and free of corrosion. Results:
OK - The machine harness connectors are tight and free of corrosion. Proceed to Test Step 3.
NOT OK - The machine harness connectors are in need of repair.Repair: Repair or replace the machine
