TRANSDUCER 6V2192 - Caterpillar

This diagnostic code is recorded when the VIMS electronic control module does not receive expected information. For example, engine speed or actual gear information is not received from other electronic control modules through the CAT data link. This diagnostic code causes the readouts, that are dependent upon the CAT data link information, to indicate abnormal values.The possible causes of this diagnostic code are listed in the order of probability:
A poor electrical connection at a machine harness connector
A circuit in the CAT data link is shorted to ground.
The CAT data link circuit in the machine harness is shorted to +battery.
The CAT data link circuit in the machine harness is open.Note: Prior to beginning the troubleshooting process, confirm that the Product ID and Equipment ID are the same. Make corrections, if necessary. Check the diagnostic clocks and synchronize, if necessary. If changes are required, shutdown the machine and run Cat® ET after switching the machine key switch to the on position. Review the code log to confirm the existence of this diagnostic code. Complete the troubleshooting process if the code is active.Test Step 1. CHECK FOR OTHER CODES.
Check for similar diagnostic codes that are logged against other electronic control modules. If a similar diagnostic code is found, exit this test and perform the corresponding procedures for the other diagnostic codes that are shown.Expected Result:Other diagnostic codes are showing.Results:
YES - Exit this procedure and perform the CID/FMI procedure for the diagnostic codes that are shown.STOP
NO - There are no other related diagnostic codes. Proceed to test step 2.Test Step 2. INSPECT THE HARNESS CONNECTORS.
Turn the key start switch and the disconnect switch to the OFF position.
Inspect the connections of the machine harness that are related to the CAT data link.
Make sure that connectors are clean and tight.Expected Result:The machine harness is correct.Results:
OK - The machine harness is correct. Proceed to test step 3.
NOT OK - The machine harness is not correct.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK FOR A SHORT TO GROUND
The key start switch and the disconnect switch remain in the OFF position.
Disconnect the machine harness from all electronic control modules that use the CAT data link.
At the machine harness connector for the VIMS electronic control module, measure the resistance between frame ground
