PLATE AS-LUMBAR 1361543 - Caterpillar

System Operation Description:Most of the switch inputs to the Engine Control Module (ECM) must be programmed to match the vehicle wiring. The switch inputs can be programmed to a specific terminal on the P1 connector or to a J1939 device on the vehicle.The engine ECM activates a diagnostic trouble code if a switch input is programmed to a J1939 device and there is a problem with the data link information for that switch input. Table 1 lists the codes that can be activated.
Table 1
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.
