Diagnostic Codes for a Switch Input That is Programmed to a J1939 Device
Diagnostic Trouble Code Conditions Which Can Cause the Code
69-9 Two Speed Axle Switch : Abnormal Update Rate The engine ECM is receiving no information about the switch input from the J1939 device. This code is caused by one of the following conditions:
The switch input is programmed to the wrong J1939 device. This is the most likely cause of the code if there is only one -9 code.
The switch input is programmed to the correct J1939 device. However, there is a problem with the J1939 device.
There is a problem with wiring for the J1939 data link between the engine ECM and the J1939 device. There may be a problem inside an electrical connector.

1321-14Engine Starter Solenoid Lockout Relay Driver Circuit - Special Instruction The Transmission Neutral Start Interlock parameter is set to Enabled and the engine does not receive a Crank Enable value of 0 or 1 from the transmission via the J1939 datalink.
The Engine Running Output is not set to pin 29, 30, or 31.
There is a problem with the wiring between the J1939 device and the ECM. Illustration 1 shows the portion of the system that can cause each diagnostic trouble code.

The following information will be helpful as you perform this procedure.
The J1939 devices that are installed on the vehicle
The list of switches that are connected to each J1939 deviceTest Step 1. Determine the Failure Mode IdentifierDetermine the type of code.Expected Result:There is a -9 code.Results:
There is a -9 code. - The engine ECM is receiving no information about the switch.Repair: Perform the following procedure:
Verify that the switch input is programmed to the correct J1939 device. Program the switch input to every possible J1939 device if you do not know the vehicle configuration. Wait for a few seconds after the switch input is programmed to a J1939 device. Then, determine if the -9 code is gone.Continue with this procedure, if necessary.
If programming the switch input does not solve the problem, there may be a problem with the J1939 device. Check for the following conditions:
The J1939 device is receiving electrical power.
The J1939 device is programmed correctly.Refer to the troubleshooting information for the J1939 device. Make the necessary repairs.
Check the wiring for the J1939 data link. The
