Pinpoint Test Z : U0151:00 (APIM (Sync Module))

WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.
  1. Refer to MODULE COMMUNICATIONS NETWORK for schematic and connector information.

    Normal Operation and Fault Conditions 

    The APIM communicates with the RCM over the CAN. If messages are missing or not received from the RCM, features such as the emergency roadside assist or the passenger airbag disable indicator may be inoperative.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    APIM U0151:00 Lost Communication With Restraints Control Module: No Sub Type Information Sets in continuous memory when the APIM detects messages from the RCM are missing for more than 5 seconds.

    Possible Sources 

    • Network communication concern
    • APIM concern
    • RCM

  2. Z1 VERIFY THE CONCERN

    • Ignition ON.

    • Verify there is an observable symptom present.

    Is an observable symptom present? 

    Yes  GO to  Z2
    No  CLEAR the DTC. The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

  3. Z2 CHECK THE COMMUNICATION NETWORK

    • Using a diagnostic scan tool, carry out the network test.

    Does the RCM pass the network test? 

    Yes  GO to  Z3
    No  REFER to: Communications Network .

  4. Z3 CHECK FOR NON-NETWORK APIM (SYNC MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, carry out the APIM self-test.

    Are any non-network Diagnostic Trouble Codes (DTCs) present? 

    Yes  DIAGNOSE all non-network Diagnostic Trouble Codes (DTCs) first. REFER to the APIM DTC Chart  in this information.
    No  GO to  Z4

  5. Z4 CHECK FOR NON-NETWORK RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, carry out the RCM self-test.

    Are any non-network Diagnostic Trouble Codes (DTCs) present? 

    Yes  REFER to: Airbag Supplemental Restraint System (SRS) - Vehicles Without: Rear Seat Side Airbag .
    No  GO to  Z5

  6. Z5 RECHECK FOR APIM (SYNC MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, clear the APIM Diagnostic Trouble Codes (DTCs).

    • Ignition OFF.

    • Ignition ON.

    • Wait 10 seconds.

    • Using a diagnostic scan tool, carry out the APIM self-test.

    Is DTC U0151:00 still present? 

    Yes  GO to  Z6
    No  The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

  7. Z6 CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK CONCERN

    NOTE: If new modules were installed prior to the DTC being set, the module configuration can be incorrectly set during the PMI or the PMI may not have been carried out.

    • CHECK the vehicle service history for recent service actions related to the RCM and the module in question setting the DTC. If recent service history is found:

      • verify correct replacement module was installed

        • vehicle parts build list may be used to verify correct part fitment

      • verify the configuration of replacement module was correct

        • re-configure module using as-built data if prior configuration is suspect

      • verify the module was not obtained from a like vehicle and installed into vehicle with concern

        • return the swapped module to source vehicle and obtain new replacement module

    • Operate the system and determine if the observable symptom is still present.

    Is the observable symptom still present? 

    Yes  GO to  Z7
    No  The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

  8. Z7 CHECK FOR CORRECT RCM (RESTRAINTS CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect all the RCM and any related in-line connectors.

    • Repair:

      • corrosion (install new connectors or terminals - clean module pins)
      • damaged or bent pins - install new terminals pins
      • pushed-out pins - install new pins as necessary

    • Reconnect the RCM and any related in-line connectors. Make sure they seat and latch correctly.

    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new RCM. REFER to: Restraints Control Module (RCM) .
    No  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
