Illustration 1 g02163817
Schematic of the Cat data link
This diagnostic code is recorded when the Advisor ECM has an abnormal update rate with the VIMS Analysis Control Module through the Cat data link.Note: Cat ET will report a CID 1089 code as a VIMS Analysis control module fault. In a VIMS 3G system the VIMS 3G Application ECM is the ECM that has created the fault.System Response:This failure results in events that are logged against the VIMS Analysis Control Module that cannot be explained directly. The Advisor ECM cannot communicate with the VIMS Analysis Control Module or the VIMS Analysis Control Module appears to communicate intermittently.Test Step 1. VERIFY THE HARDWARE AND THE SOFTWARE PART NUMBERS.
Verify that the following information is correct:
The part number of the Advisor ECM onboard software
The part number of the flash software for the VIMS Analysis Control Module
The part number of the Advisor ECM
The part number of the VIMS Analysis Control ModuleNote: Consult the Business Unit that produces the product for the correct part numbers of the configuration software.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: The installed Advisor ECM or the VIMS Analysis Control Module has the wrong part number or the incorrect configuration software is installed. Replace the incorrect Advisor ECM or the VIMS Analysis Control Module with an ECM that has the correct part number. Refer to Service Manual, "Electronic Control Module (ECM) - Replace". Flash the correct configuration software. Refer to Service Manual, "Electronic Control Module (ECM) - Flash Program".STOPTest Step 2. INSPECT THE HARNESS CONNECTIONS.
Turn the disconnect switch to the OFF position.
Inspect all harness connections that are related to
