This diagnostic code indicates the VIMSTM ECM is not sending the necessary parameters to the "Chassis" ECM at the proper rate. The parameters update rate generated by the VIMS ECM is not correct.This diagnostic code could be caused by:
Failed VIMS ECM fuse
Incorrect VIMS ECM software
Incorrect "Chassis" ECM software
Incompatible software
Harness failure
ECM failureTest Step 1. CHECK FUSE
Turn off the key switch and the disconnect switch.
Check the VIMS ECM fuse.Expected Result:Fuse has not failed.Results:
OK - Fuse has not failed. Proceed to Test Step 2.
NOT OK - Fuse has failed.Repair: Replace the fuse.STOPTest Step 2. CHECK SOFTWARE
Use Cat® Electronic Technician (Cat® ET) to verify that the software versions are correct and compatible.Expected Result:The proper software is installed.Results:
OK - The proper software is installed. Proceed to Test Step 3.
NOT OK - The proper software is not installed.Repair: Flash the proper software to the appropriate ECM.Cycle the key switch to initialize the new software.Ensure that the diagnostic code is no longer active.STOPTest Step 3. CHECK THE HARNESS
Inspect the harness.Clean and inspect the harness connector contacts for corrosion or damage.Check the wire insulation for damage caused by heat, corrosion, or chafing.
Perform a 45 N (10 lb) pull test on each circuit wire.
Reconnect all harness connectors.Verify that the connectors are fully seated and the clips are fastened.
Check for intermittent problems. Use Cat® Electronic Technician (Cat® ET) to perform a wiggle test on the harness.
Turn on the disconnect switch and the key switch.
Operate the machine.
Determine if the CID 800 FMI 14 diagnostic code is active.Expected Result:CID 800 FMI 14 is not active.Results:
OK - CID 800 FMI 14 is not active.Repair: The initial diagnostic code was probably caused by a poor connection at one of the connectors that was checked.Clear the diagnostic code.STOP
NOT OK - CID 800 FMI 14 is active. Proceed to Test Step 4.Test Step 4. CHECK THE CAT DATA-LINK CIRCUITThe key switch and the disconnect switch are in the off position.
Disconnect the harness from all the ECM modules in the Cat Data Link circuit.
Measure the resistance between the harness connector contacts for the following:
VIMS ECM Cat Data Link + and "Chassis" ECM Cat Data Link +
VIMS ECM Cat Data Link - and "Chassis" ECM Cat Data Link -
Reconnect all disconnected ECM modules.Expected Result:The resistance is greater than 5000 ohms.Results:
OK - The resistance is greater than 5000 ohms. The VIMS ECM may have failed.Repair: Exit this procedure and perform this procedure again. Contact the technical communicator at your Caterpillar dealer. If the ECM requires replacement, see Testing and Adjusting, "Electronic Control Module (ECM) - Replace".STOP
NOT OK - The resistance is less than 5 ohms. The circuit is shorted.Repair: Repair or replace the harness.STOP
