Pinpoint Test AE: Unable To Activate Self Test/Network Communication Error
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.
Refer to ELECTRONIC ENGINE CONTROLS - 3.0L DIESEL for schematic and connector information.
Normal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions.

| PCM U0155:00 | Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information | Sets when the PCM does not receive the IPC control module message within the defined amount of time. |
| PCM U0212:00 | Lost Communication With Steering Column Control Module: No Sub Type Information | Sets when the PCM detects invalid data from the SCCM. Check for other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms. Diagnose all other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms first. |
| PCM U0307:00 | Software Incompatibility with Glow Plug Control Module 1: No Sub Type Information | Sets when the PCM detects invalid data from the glow plug control module. |
| PCM U030F:00 | Software Incompatibility With Reductant Control Module: No Sub Type Information | Sets when the PCM detects invalid data from the RDCM. The presence of this DTC may indicate the vehicle is operating in derate mode and may experience a loss of power. After repair, the vehicle may still display a system warning message. Drive the vehicle until the system warning message has cleared from the IPC message center. |
| PCM U0402:00 | Invalid Data Received from TCM: No Sub Type Information | Sets when the PCM detects invalid data from the TCM. This DTC sets when network DTC concerns occur during module to module communication. Check for other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms. Diagnose all other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms first. Check for TCM Diagnostic Trouble Codes (DTCs) or TCM related symptoms. Diagnose all other TCM Diagnostic Trouble Codes (DTCs) or TCM related symptoms first. |
| PCM U0407:00 | Invalid Data Received From Glow Plug Control Module 1: No Sub Type Information | Sets when the PCM detects invalid data from the glow plug control module. This DTC sets when network DTC concerns occur during module to module communication. Check for other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms. Diagnose all other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms first. |
| PCM U0418:00 | Invalid Data Received from Brake System Control Module "A": No Sub Type Information | Sets when the PCM detects invalid data from the ABS module. This DTC sets when network DTC concerns occur during module to module communication. Check for other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms. Diagnose all other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms first. Check for other ABS control module Diagnostic Trouble Codes (DTCs) or ABS control module related symptoms. Diagnose all other ABS control module Diagnostic Trouble Codes (DTCs) or ABS control module related symptoms first |
| PCM U0419:00 | Invalid Data Received From Steering Effort Control Module: No Sub Type Information | Sets when the PCM detects invalid data from the SECM. This DTC sets when network DTC concerns occur during module to module communication. Check for other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms. Diagnose all other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms first. |
| PCM U041E:00 | Invalid Data Received From All Wheel Drive Control Module: No Sub Type Information | Sets when the PCM detects invalid data from the AWD module. This DTC sets when network DTC concerns occur during module to module communication. |
| PCM U0422:00 | Invalid Data Received From Body Control Module: No Sub Type Information | Sets when the PCM detects invalid data from the BCM. This DTC sets when network DTC concerns occur during module to module communication. Check for other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms. Diagnose all other PCM Diagnostic Trouble Codes (DTCs) or PCM related symptoms first. |
| PCM U0452:00 | Invalid Data Received From Restraints Control Module: No Sub Type Information | Sets when the PCM detects invalid data from the RCM.
