Schematic diagram showing the connections for the Cat Data Link
This diagnostic code is recorded when the Brake ECM receives information from one of the following electronic control modules and the information is NOT correct.
Engine ECM
Chassis ECMNote: 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 Engine ECM
Software part number for the Chassis ECMExpected Result:Consult the Business Unit that is producing the product for the correct configuration for the machine.Results:
OK - All part numbers are correct. Proceed to Test Step 2.
NOT OK - All of the part numbers are NOT correct. Repair: One of the modules that are listed above may have the wrong part number and/or the software configuration is NOT correct. 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 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 OK - The machine harness connectors require repair. Repair: Repair or replace the machine 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 related 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 the CID 0967 FMI 09. If the CID 0967 FMI 09 remains active, perform CID 0967 FMI 09 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, measure the resistance between J1-10 and frame ground. Expected Result:The resistance is greater than 5000 ohms.Results:
OK - The resistance is greater than 5000 ohms. The harness circuit is correct. Proceed to Test Step 5.
NOT OK - The resistance is NOT greater than 5000 ohms. The machine harness has failed.Repair: There is a short between frame ground and the data link circuit in the
