Pinpoint Test Aw: Invalid Data Received From Another Module

WARNING: This page is about a different car, the 2022 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
  1. Normal Operation and Fault Conditions 

    The AWD module expects to receive network data from other modules on HS-CAN1. The AWD will set a DTC when it receives an invalid or incomplete messages from another module. Incomplete or corrupted messages typically result from high network traffic preventing the complete message from being received within the calibrated time limit.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    AWD U0401:00 Invalid Data Received from ECM/PCM A: No Sub Type Information Sets when the AWD module received a message from the suspect, but the message was not complete.
    AWD U0415:00 Invalid Data Received from Anti-Lock Brake System (ABS) Control Module "A": No Sub Type Information Sets when the AWD module received a message from the suspect, but the message was not complete.
    AWD U0422:00 Invalid Data Received From Body Control Module: No Sub Type Information Sets when the AWD module received a message from the suspect, but the message was not complete.
    AWD U0423:00 Invalid Data Received from Instrument Panel Cluster Control Module: No Sub Type Information Sets when the AWD module received a message from the suspect, but the message was not complete.
    AWD U0428:00 Invalid Data Received From Steering Angle Sensor Module: No Sub Type Information Sets when the AWD module received a message from the suspect, but the message was not complete.
    AWD U1012:00 Invalid Internal Control Module Monitoring Data Received from Anti-Lock Brake System (ABS) Control Module: No Sub Type Information Sets when the AWD module received a message from the suspect, but the message was not complete.
    AWD U1014:00 Invalid Internal Control Module Monitoring Data Received from Restraints Control Module: No Sub Type Information Sets when the AWD module received a message from the suspect, but the message was not complete.

    Possible Sources 

    • High network traffic event
    • Intermittent network connection
    • Suspect module
    • AWD module

  2. AW1 ATTEMPT TO DUPLICATE THE DTC (DIAGNOSTIC TROUBLE CODE)

    • Enter the following diagnostic mode: Clear and Retest the AWD CMDTC self-test.

    • Road test the vehicle.

    • Enter the following diagnostic mode: AWD module CMDTC self-test.

    Did the invalid data DTC set again? 

    Yes  For all other DTC, GO to  AW3
    No  The system is operating correctly at this time. The concern may have been caused by a high network traffic event.

  3. AW2 CHECK THE AWD (ALL-WHEEL DRIVE) MODULE GROUND

    • Ignition OFF.

    • Verify AWD module retaining nuts are secure. Torque: 89 lb. in (10 Nm)

    Were any of the fasteners loose? 

    Yes  TIGHTEN the AWD module nuts to specification. RETEST the system for normal operation.
    No  GO to  AW3

  4. AW3 INSPECT HS-CAN1 (HIGH-SPEED CONTROLLER AREA NETWORK 1) CONNECTOR

    • Refer to MODULE COMMUNICATIONS NETWORK for schematic and connector information. DISCONNECT and INSPECT the HS-CAN1 connectors between the AWD and the suspect module.

    • Repair:

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

    • Connect all connectors. Make sure each connector seats and latches correctly.

    • Operate the system and verify the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable TSB. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSB address this concern, INSTALL a new suspect module. For U0401, INSTALL a new ECM/PCM "A". INSTALL a new PCM. Refer to Powertrain Control Module (PCM) - 1.5L EcoBoost (132kW 180PS) , or Powertrain Control Module (PCM) - 2.0L EcoBoost (177kW 240PS) . For U0415, INSTALL a new ABS module. REFER to: Anti-Lock Brake System (ABS) and Stability Control . For U0422, INSTALL a new BCM. REFER to: Body Control Module (BCM) . For U0423, INSTALL a new IPC module. REFER to: Instrument Panel Cluster (IPC) . For U0428, INSTALL a new SCCM. REFER to: Steering Column Control Module (SCCM) . For U1012, INSTALL a new ABS. REFER to: Anti-Lock Brake System (ABS) Module - Vehicles With: Vacuum Brake Booster . For U1014, 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.
