Pinpoint Test QA: Unable To Activate Self-Test/Network Communication Error
WARNING: This page is about a different car, the 2023 Ford Bronco. However, it is still accessible from the selected car via links, so may be relevant.
Normal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions below.
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 P0606:00 | Control Module Processor: No Sub Type Information | Sets when the PCM detects an internal communication error. 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 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 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. |
