Cat® data-linkNote: MID 161 is generated by one ECM, this ECM is referred to as the following in various venues:
Communication Gateway 1 ECM
VIMS Main Module, in Caterpillar® Electronic Technician Cat® (ET)
VIMS 3G Main ECM, in this publication This diagnostic code is recorded when the VIMS 3G Main ECM does not receive expected information from the Transmission ECM at the correct rate. The information is transmitted through the Cat® data-link.System Response:This failure results in events that are logged against the Transmission ECM that cannot be explained. The VIMS 3G Main ECM cannot communicate with the Transmission ECM or the Transmission ECM appears to communicate intermittently.Test Step 1. VERIFY THE HARDWARE AND THE SOFTWARE PART NUMBERS
Verify that the following information is correct:
VIMS 3G Main ECM onboard software part number
Transmission ECM flash software part number
VIMS 3G Main ECM part number
Transmission ECM part numberNote: For the correct part configuration software numbers, consult the business unit that produces the product.Expected Result:All part numbers are correct. Results:
OK - All part numbers are correct. Proceed to Test Step 2.
NOT OK - All part numbers are not correct. Repair: Replace the incorrect VIMS 3G Main ECM or the Transmission ECM with an ECM that has the correct part number. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace". Flash the correct configuration software. See Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program".STOPTest Step 2. INSPECT THE HARNESS
Turn off the disconnect switch.
Inspect Cat data-link harness for the following:
Inspect the connectors, pins, and sockets for the following:
Cleanliness
Security

AbrasionNote: Take care not to pull the wire out of the connector.
Inspect the harness for the following:
Damage
Abrasion
KinksExpected Result:The harness is in good condition.Results:
OK - The harness is in good condition. Proceed to Test Step 3.
NOT OK - The harness is not in good condition.Repair: Repair or replace the harness. STOPTest Step 3. CHECK FOR SHORTS TO GROUND The disconnect switch remains off.
