Communication Gateway #1 ECM (VIMS Main ECM) MID 161
Communication Gateway #2 ECM (VIMS Application ECM) MID 162    
DTC    Code Description    System Response    
246-9     Proprietary CAN Data Link - Abnormal Update Rate     There is a lack of VIMSTM communication on a data link.    
533-9     Brake Control - Abnormal Update Rate     There is a lack of communication between VIMS and the Brake ECM.    
590-9     Engine Control Module - Abnormal Update Rate     There is a lack of communication between VIMS and the Engine ECM.    
800-9     VIMSTM Main Module - Abnormal Update Rate     There is a lack of VIMS communication on a data link.    
890-9     Telemetry Data Link - Abnormal Update Rate     There is a lack of communication between VIMS and the telematic components.    
1089-9     VIMS Analysis Control Module - Abnormal Update Rate     There is a lack of VIMS communication on a data link.    
1273-9     Chassis Control Module - Abnormal Update Rate     There is a lack of communication between VIMS and the Chassis ECM.    
3050-9     Drivetrain Control - Abnormal Update Rate     There is a lack of communication between VIMS and the Drivetrain ECM.    
3643-9     Motor Control #1 - Abnormal Update Rate     There is a lack of communication between VIMS and Motor Control #1.    
3644-9     Motor Control #2 - Abnormal Update Rate     There is a lack of communication between VIMS and Motor Control #2.    Each data link circuit:
Is an input and output of select electronic control modules (ECMs)
Is designed to carry communications between the ECMs
Consists of internal control circuits and the connecting harness wiringPossible Causes for a Data Link Associated Diagnostic Trouble Code Are:
Poor ECM connections on the data link
Incorrect ECM hardware or software part numbers
Failed data link harness
Failed ECM on the data link

Troubleshooting Steps    Values    Results    
1. Check for Diagnostic Codes
A. Connect Cat® Electronic Technician (Cat ET) to the machine.
B. Check for active codes.    
There are no active data link associated codes    
OK - There are no active data link associated codes.
STOP
Not OK - There are active data link associated codes.
Go to Step 2.    
2. Check Connectors
A. Inspect the circuit harness connectors.    
Connectors are:
* Clean
* Secure
* In good condition    
OK - Connectors are OK.
Go to Step 3.
Not OK - Connectors are not OK.
Repair:
A. Correct any connection problem.
B. Verify that the problem is corrected.
STOP    
3. Check the Hardware Part Numbers and the Software Versions
A. On Cat ET, click "ECM Summary".
B. Check "Software Group" for info (1).    
*Hardware is the correct part number
*Software is the latest version    
OK - The hardware and software are correct.
Go to Test Step 4.
NOT OK - The hardware or software are not correct.
Repair:
A. Install correct part number ECMs, if necessary (2).
A. Update the software (3).
B. Clear the diagnostic
