Connections of the CAN A Data LinkThis diagnostic code is recorded if the Transmission ECM determines that information on the keypad data link is erratic or the information makes no sense.System Response:This condition causes the keypad to operate erratically or the keypad may not function at all.Test Step 1. INSPECT THE BUTTONS ON THE KEYPAD.
Turn the disconnect switch to the OFF position.
Inspect the buttons for the keypad in order to ensure that the buttons operate smoothly.
Toggle each button on the keypad.Expected Result:The buttons appear to move smoothly. Results:
OK - The buttons appear to move smoothly. Proceed to test step 2.
NOT OK - One or more of the buttons appear to be improperly activated. The face plate of the Transmission ECM is causing one or more of the buttons to be improperly activated.Repair: Either remove the face plate and reinstall the face plate or manipulate the buttons in order to ensure smooth operation.STOPTest Step 2. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Turn the disconnect switch and the key start switch to the ON position.
Clear all inactive diagnostic codes.
Operate the machine.
Check the status of CID 3583 FMI 07.Expected Result:The diagnostic code is NO longer active.Results:
YES - The diagnostic code is NO longer active. The diagnostic code does NOT exist at this time. The initial diagnostic code was probably caused by a poor electrical connection of the buttons for the Transmission ECM. Resume normal machine operation.STOP
NO - The diagnostic code remains active. Failure of the ECM is unlikely.Repair: Exit this procedure and perform this procedure again. If the cause of the problem is not found, the ECM may have failed.Prior to replacing an ECM, always contact your Technical Communicator for possible consultation with Caterpillar. This consultation may greatly reduce repair time. If the cause of the diagnostic code is not found and the ECM must be replaced, refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace".STOP
