Diagnostic Trouble Codes for the Data Link Circuit    
J1939 Code    Description    Notes    
1196-2     Anti-theft Component Status States : Erratic, Intermittent, or Incorrect     The engine Electronic Control Module (ECM) detects poor communications with the Machine Security System (MSS).
The ECM will log the diagnostic code.
The engine will not start.    
1231-9     J1939 Network #2 : Abnormal Update Rate     The engine ECM detects a loss of communications with the CAN B data bus.
The ECM will log the diagnostic code.
The engine will not start.    
1196-9     Anti-theft Component Status States : Abnormal Update Rate     The engine ECM detects a loss of communications with the Machine Security System (MSS).
The ECM will log the diagnostic code.
The engine will not start.    Use this procedure if the electronic service tool will not communicate with the ECM through the data link.The following background information is related to this procedure:The data link is the standard data link that is used by the ECM in order to communicate with the electronic service tool.The ECM provides multiple connections for the data link. The technician must ensure that the correct connector is being tested. The connection that is used is dependent on the application.The diagnostic connector is on the right-hand side of the left-hand operator console. The positive data link signal is from P1:8 to pin "D" of the diagnostic connector. The negative data link signal is from P1:9 to pin "E" of the diagnostic connector.The following information refers to the pin number. Ensure that the correct connector is used.CommunicationThe electronic service tool may indicate the following error message:The version of the ECM is not recognized and the integrity of the changed parameters and displayed data is not guaranteed.This message will indicate that the version of the software that is in the electronic service tool is obsolete. Install the latest version of the software for the electronic service tool in order to rectify the fault.

Thoroughly inspect the following electrical connectors:
P1/J1 ECM connector
The connection for the diagnostic connectorRefer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connectors that are associated with the data link.
Check the screw for the ECM connectors for correct torque of 6 N m (53 lb in).
Check the harness for abrasion and pinch points from the wires that connect the diagnostic connector to the ECM.Expected Result:All connectors, pins, and sockets are correctly connected and/or inserted. The harness should be free of corrosion, abrasion and/or pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Perform the following repair:Repair the connectors and/or the harness, or replace the connectors and/or the harness. Ensure that all of the seals are correctly in place and ensure that the connectors are correctly connected.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 2. Determine the Type of Fault in the Data Link
Connect the electronic service tool to the diagnostic connector that is on the engine harness or on the application.
Turn the keyswitch to the ON position.Expected Result:The power lamp should illuminate on the communications adapter. The power lamp on the communications adapter may illuminate when the keyswitch is in any position.Results:
OK - The communications adapter is currently receiving the correct voltage. Proceed to Test Step 5.
Not OK - The communications adapter is not receiving the correct voltage. Proceed to Test Step 3.Test Step 3. Check the Battery Voltage at the Diagnostic Connector
Turn the keyswitch to the ON position.
Use a multimeter in order to measure the voltage from pin A (battery+) and pin B (ground) of the diagnostic connector.Expected Result:The voltage is between 22.0 VDC and 27.0 VDC.Results:
The diagnostic connector is currently receiving the correct voltage. - Proceed to Test Step 5.
The diagnostic connector is not receiving the correct voltage. - Proceed to Test Step 4.Test Step 4. Bypass the Wiring for the Diagnostic Connector

Disconnect the wires from pin A and pin B of the diagnostic connector.
Fabricate a jumper wire in order to connect pin "A" of the diagnostic connector to battery+ and pin "B" to the battery-.
Connect the electronic service tool to the diagnostic connector.
Turn the keyswitch to the ON position.Expected Result:The power lamp should illuminate on the communications adapter. The power lamp on the communications adapter may illuminate when the keyswitch is in any position.Results:
The power lamp is illuminated - The fault is in the harness.Repair: Repair the faulty harness or replace the faulty harness.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOP
The power lamp is not illuminated. - Repair: Proceed to Test Step 6.Test Step 5. Check the Data Link Connections
Turn the keyswitch to the OFF position.
Disconnect the communications adapter from the diagnostic connector.
Disconnect connector P1 from the ECM. Check the resistance between P1:8 and pin "D" on the diagnostic connector.
Check the resistance between P1:9 and pin "E" on the diagnostic connector.Results:
The resistance is less than ten Ohms - Proceed to Test Step 6.
The resistance is greater than ten Ohms. - Repair: Perform the following repair:Repair the connectors and/or the harness, or replace the connectors and/or the harness. Ensure that all of the seals are correctly in place and ensure that the connectors are correctly connected.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 6. Change the Electronic Service Tool Components
If another electronic engine is available, connect the electronic service tool to the other engine. Ensure that
