Pinpoint Test QA: 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.
Refer to Wiring Diagrams Electronic Engine Controls - 2.7L for schematic and connector information.
Normal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PCM P0604:00 | Internal Control Module Random Access Memory (RAM) Error: No Sub Type Information | Sets when the PCM detects the RAM is corrupt. Reprogram or update the calibration. Check for other Diagnostic Trouble Codes (DTCs) or drive symptoms for further action. Check for aftermarket performance products. |
| PCM P0605:00 | Internal Control Module Read Only Memory (ROM) Error: No Sub Type Information | Sets when the PCM detects the ROM is corrupt. Reprogram the vehicle identification block. Check for other Diagnostic Trouble Codes (DTCs) or drive symptoms for further action. Check for aftermarket performance products. Refer to Flash EEPROM, Programming the (VID) Block for a Replacement PCM. |
| PCM P0607:00 | Control Module Performance: No Sub Type Information | Sets when the PCM detects the internal central processing unit (CPU) encounters an error. The PCM monitors itself and carries out internal checks of its own CPU. This DTC sets if any of these checks returns an incorrect value. Reprogram or update the calibration. Check for other Diagnostic Trouble Codes (DTCs) and diagnose those first. Check for aftermarket performance products. Clear the Diagnostic Trouble Codes (DTCs), repeat the self-test. |
| PCM P0630:00 | VIN Not Programmed or Incompatible - ECM/PCM: No Sub Type Information | Sets when the PCM detects various VID data that is out of a specified acceptable range. The PCM did not receive a valid vehicle identification number (VIN) during reprogramming. Check for all other module Diagnostic Trouble Codes (DTCs) or related symptoms. Diagnose all other module Diagnostic Trouble Codes (DTCs) before diagnosing this DTC. Reprogram the BCM, instrument cluster, and PCM using as built data. Refer to Flash EEPROM, Programming The VID Block For A Replacement PCM, to reprogram the PCM. |
| PCM P064F:00 | Unauthorized Software/Calibration Detected: No Sub Type Information | Sets when the PCM detects an unauthorized calibration. |
| PCM P160A:00 | Control Module Vehicle Options Reconfiguration Error: No Sub Type Information | Sets when the PCM detects a mismatch in configuration data and programmable parameters between the PCM and BCM. |
| PCM P161C:00 | Automatic Engine Shutdown Mismatch with Vehicle Configuration: No Sub Type Information | Sets when the IPC detects a mismatch in configuration data and programmable parameters between the PCM and the IPC. |
| PCM P1935:00 | Brake Switch/Sensor Signal: No Sub Type Information | Sets when the PCM does not receive the ABS message within the defined amount of time. The PCM continuously monitors the CAN for messages from the ABS module. Check for other ABS Diagnostic Trouble Codes (DTCs) or ABS related symptoms. Diagnose all other ABS Diagnostic Trouble Codes (DTCs) or ABS related symptoms first. |
| PCM U0138:00 | Lost Communication with All Terrain Control Module: No Sub Type Information | Sets when the PCM does not receive the ATCM message within the defined amount of time. The PCM continuously monitors the CAN for messages from the ATCM. 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 U0140:00 | Lost Communication With Body Control Module: No Sub Type Information | Sets when the PCM does not receive the BCM message within the defined amount of time. The PCM continuously monitors CAN for messages from BCM. 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 U0422:00 | Invalid Data Received From Body Control Module: No Sub Type Information | Sets when the PCM detects invalid data concerns - data is transferred within the normal inter-module message, but contains known invalid data. Network DTC concerns occur during module to module communication. The transmitting module logs a DTC related to the invalid data concern. Check for all other module Diagnostic Trouble Codes (DTCs) or related symptoms. Diagnose all other module Diagnostic Trouble Codes (DTCs) before diagnosing this DTC. Reprogram the BCM, instrument cluster, and PCM using as built data. Refer to Flash EEPROM, Programming The VID Block For A Replacement PCM, to reprogram the PCM. |
| PCM U1012:00 | Invalid Internal Control Module Monitoring Data Received from Anti-Lock Brake System (ABS) Control Module: No Sub Type Information | Sets when the PCM receives invalid data from the ABS module, indicating a concern with module configuration or sensor input to the ABS module. Diagnose all Diagnostic Trouble Codes (DTCs) set by the ABS module first. |
| PCM U2100:00 | Initial Configuration Not Complete: No Sub Type Information | Sets when the PCM detects a programming error within the vehicle identification (VID) block. Program the VID block. Refer to Flash EEPROM, Making Changes to the VID Block. If the PCM does not allow reprogramming of the VID block, reflashing of the PCM is required. |
| PCM U2101:00 | Control Module Configuration Incompatible: No Sub Type Information | Sets when the PCM detects the RAM is corrupt. Reprogram or update the calibration. Check for other Diagnostic Trouble Codes (DTCs) or drive symptoms for further action. Check for aftermarket performance products. Refer to Flash EEPROM, Programming the VID Block for a replacement PCM. |
| PCM U2200:00 | Control Module Configuration Memory Corrupt: No Sub Type Information | Sets when the PCM detects a programming error within the vehicle identification (VID) block. Program the VID block. Refer to Flash EEPROM, Making Changes to the VID Block. If the PCM does not allow reprogramming of the VID block, reflashing of the PCM is required. |
