      I ha e a question about this. I could see doing the proxi if it was just the flashing odometer.. but with the check engine light code as well would that mean there is an issue with the bcm anyways?

      Anytime you do an upgrade like fog lights, the bcm needs a PROXI or the upgrade will not work. The flashing odometer means the bcm detected a change from it's original configuration. Usually a PROXI fixes that. Your BCM isn't happy after a PROXI. Hence the code.

      Ok! So good news! I had read somewhere that when you clear codes with alfaobd, you have to do it a certain way... turn the key to mar and clear the code, then take out the key, lock the doors, and wait a little while . I had tried that this morning and I have no more flashing odometer 😁 but my speakers are still messed up... I performed another proxy alignment, and did it the same way. Car was running why I did the proxy, then took out the key and locked the doors. I will see tomorrow morning if that fixes anything... but no more flashing odometer is a start 😊

      NOTE: Diagnose Lost Communication DTCs (not to be confused with CAN Bus Off or Can Bus Performance DTCs) before diagnosing other CAN related DTCs.

      Which type of Communication DTC is active?

      Lost Communication

      •Go To 7

      Implausible Data, Implausible Signal, Missing Message, or Invalid Data

      •Go To 9



      5.CHECK STORED DTCS

      1. Refer to the Vehicle Scan Report.

      NOTE: Diagnose all Lost Communication DTCs before diagnosing other CAN related DTCs.

      Which type of Communication DTC is stored?

      Lost Communication

      •Perform the STORED LOST COMMUNICATION DTCS procedure. (Refer to 29 - Non-DTC Diagnostics/Communication/Diagnosis and Testing) .

      Implausible Data, Implausible Signal, Missing Message, or Invalid Data

      •Go To 6



      6.CHECK OFFENDING CONTROL MODULE FOR DTCS

      NOTE: The ‘Offending Control Module’ is the module that the Implausible DTC is set against.

      1. Refer to the Vehicle Scan Report.

      Are any DTCs set in the Offending Control Module?

      Yes

      •Refer to the appropriate diagnostic procedure.

      No

      •Go To 11



      7.CHECK FOR MULTIPLE LOST COMMUNICATION DTCS

      1. Refer to the Vehicle Scan Report.

      Choose the scenario that best describes the condition of the vehicle from the list below:

      One module is reporting a Lost Communication DTC against a single Control Module.

      •Go To 8

      Multiple Control Modules are reporting a Lost Communication DTC against a single Control Module.

      •Perform the NO RESPONSE diagnostic procedure for the Control Module that is not communicating. (Refer to 29 - Non-DTC Diagnostics/Communication/Diagnosis and Testing) .



      8.CHECK OFFENDING CONTROL MODULE FOR COMMUNICATION

      NOTE: The ‘Offending Control Module’ is the module that the Loss of Communication DTC is set against.

      1. Refer to the Vehicle Scan Report.

      Is the Offending Control Module active on the bus?

      Yes

      •Replace the Reporting Control Module in accordance with the Service Information.
      •Perform the appropriate VERIFICATION TEST. If a VERIFICATION TEST is not available for that Control Module, perform the BCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Body Control (BCM) /Standard Procedure).

      No

      •Perform the NO RESPONSE diagnostic procedure for the module that is not communicating. (Refer to 29 - Non-DTC Diagnostics/Communication/Diagnosis and Testing) .



      9.CHECK OFFENDING CONTROL MODULE FOR DTCS

      NOTE: The ‘Offending Control Module’ is the module that the Implausible Data, Implausible Signal, Missing Message, or Invalid Data DTC is set against.

      1. Refer to the Vehicle Scan Report.

      With the scan tool, check the Offending Control Module for non-U-code DTCs that are related to the U-code that is set, or related to the customer complaint if the U-code DTC name is not clear about which signal is faulted.

      Yes

      •Refer to the appropriate diagnostic procedure.

      No

      •Go To 10



      10.CHECK OTHER CONTROL MODULES FOR RELATED NON U-CODE DTCS

      NOTE: IMPORTANT: Some Control Modules simply pass information from one Control Module to the other. In some cases, a U-code DTC may be set that implicates the “pass-through” module that sent the information. For example, if an Engine Coolant Temperature (ECT) Sensor DTC is set in the Powertrain Control Module (PCM), the HVAC module may set an “Implausible Data from BCM” DTC because the BCM is the module that normally passes that information from the PCM to the HVAC module. However, the BCM may not set any DTCs related to the faulted ECT Sensor because the BCM does not use the ECT information. In this case, the PCM ECT DTC should be diagnosed before the Implausible Data DTC. If you suspect a scenario like this, diagnose the non U-code DTC(s) before diagnosing any Implausible Data, Implausible Signal, Invalid Data, or Missing Message DTCs.

      1. With the scan tool, check all other Control Modules for non-U-code DTCs that are related to the U-code that is set, or related to the customer complaint if the U-code DTC name is not clear about which signal is faulted.

      Is a related non U-code DTC set in another Control Module?

      Yes

      •Diagnose the related DTC. Refer to the appropriate Diagnostic Procedure.

      No

      •Replace the Offending Control Module in accordance with the Service Information.
      •Perform the appropriate VERIFICATION TEST. If a VERIFICATION TEST is not available for that module, perform the BCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Body Control (BCM) /Standard Procedure).



      11.CHECK RELATED WIRE HARNESS CONNECTIONS

      1. Disconnect all related wire harness connectors.

      2. Disconnect all related in-line wire harness connections (if equipped).

      3. Inspect wire harness connectors, component connectors, and all male and female terminals for the following conditions:
      •Proper connector installation.
      •Damaged connector locks.
      •Corrosion.
      •Signs of water intrusion.
      •Weather seal damage (if equipped).
      •Bent terminals.
      •Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
      •Terminals that have been pushed back into the connector cavity.
      •Perform a terminal drag test on each connector terminal to verify proper terminal tension.

      Repair any conditions that are found.

      4. Reconnect all related wire harness connectors. Be certain that all wire harness connectors are fully seated and the connector locks are fully engaged.

      5. Reconnect all in-line wire harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.

      6. With the scan tool, erase DTCs.

      7. Using the Vehicle Scan Report, operate the vehicle in the conditions that set the DTC.

      8. With the scan tool, read DTCs.

      Did the DTC return?

      Yes

      •If there is a history of this DTC setting multiple times, replace the Offending Control Module in accordance with the Service Information.
      •Perform the appropriate VERIFICATION TEST. If a VERIFICATION TEST is not available for that Control Module, perform the BCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Body Control (BCM) /Standard Procedure).

      No

      •Perform the appropriate VERIFICATION TEST. If a VERIFICATION TEST is not available for that Control Module, perform the BCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Body Control (BCM) /Standard Procedure).
      •Test complete.
