Ford Ecosport: Supplemental Restraint System / Diagnosis and Testing - Pinpoint Test - DTC: Y

Ford Ecosport 2014-2025 Service and Repair Manual / Body and Paint / Supplemental Restraint System / Diagnosis and Testing - Pinpoint Test - DTC: Y

U2300:55, U2300:64


Refer to Wiring Diagrams Cell 46 for schematic and connector information.

NOTE: DTC U2300:55 is set in every new RCM installed until configuration data is successfully received from the BCM . Do not install any new components for this DTC unless directed to do so in the pinpoint test.

Normal Operation and Fault Conditions

On the first ignition cycle after a new RCM is installed, the BCM sends a configuration data message to the RCM during the RCM prove out. During prove-out of each subsequent ignition cycle, the BCM sends configuration data to the RCM and the RCM compares the message to the data stored in memory from the very first ignition cycle.


  DTC Fault Trigger Conditions


  DTC Description Fault Trigger Conditions
U2300:55 Central Configuration: Not Configured This DTC is present in every new RCM . Once the new RCM is installed and successfully receives a configuration data message from the BCM , this DTC reports as a Continuous Memory Diagnostic Trouble Code (CMDTC). If the RCM reports this DTC on-demand, the configuration data message has not been received from the BCM .
U2300:64 Central Configuration: Signal Plausibility Failure This DTC sets if the RCM receives a configuration data message that does not match the configuration data that was previously received and stored. This DTC sets on-demand during the RCM prove-out, then changes to a Continuous Memory Diagnostic Trouble Code (CMDTC) later in the ignition cycle when the correct message is received. This DTC also sets if PMI has not been carried out for the BCM .

Possible Causes

  • RCM or BCM configuration
  • BCM
  • RCM

PINPOINT TEST A: U2300:55, U2300:64
NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
A1 RETRIEVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

  WARNING: Before beginning any service procedure in this section, refer to Safety Warnings in section 100-00 General Information. Failure to follow this instruction may result in serious personal injury.


  • REFER to: Health and Safety Precautions (100-00 General Information, Description and Operation).
  • Ignition ON.
  • Using a diagnostic scan tool, perform RCM self-test.
  • Record the RCM Diagnostic Trouble Codes (DTCs) that were retrieved during the self-test.

Is DTC U2300:55 or U2300:64 retrieved on-demand?
Yes GO to A2
No If DTC U2300:55 or U2300:64 is retrieved as a Continuous Memory Diagnostic Trouble Code (CMDTC), CLEAR the RCM Diagnostic Trouble Codes (DTCs) and REPEAT the self-test.
If DTC U2300:55 or U2300:64 does not return, RELEASE the vehicle to the customer.
If DTC U2300:55 or U2300:64 returns on-demand, GO to A2

A2 CHECK FOR THE CORRECT BCM (BODY CONTROL MODULE)
  • Using the Log Viewer function of the diagnostic scan tool, retrieve and record the BCM part number.
  • Check the recorded part number against the number listed in the Ford parts catalog.

Does the recorded part number match the number listed in the Ford parts catalog?
Yes GO to A3
No INSTALL the correct BCM and USE As-Built data when carrying out PMI . GO to A4

A3 CHECK FOR THE CORRECT RCM (RESTRAINTS CONTROL MODULE)
  • Using the Log Viewer function of the diagnostic scan tool, retrieve and record the RCM part number.
  • Check the recorded part number against the number listed in the Ford parts catalog.

Does the recorded part number match the number listed in the Ford parts catalog?
Yes CARRY OUT PMI for the BCM using As-Built data. CLEAR the Diagnostic Trouble Codes (DTCs) and REPEAT the RCM self-test.
If DTC U2300:55 or U2300:64 are retrieved, CARRY OUT PMI for the RCM using As-Built data.
GO to A4
No INSTALL the correct RCM and use As-Built data when carrying out PMI .
REFER to: Restraints Control Module (RCM) (501-20B Supplemental Restraint System, Removal and Installation).
GO to A4

A4 CHECK FOR ADDITIONAL RCM (RESTRAINTS CONTROL MODULE) OR BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

NOTE: Make sure all SRS components and the RCM electrical connectors are connected before carrying out the self-test. If not, Diagnostic Trouble Codes (DTCs) will be recorded.

  • Ignition ON.
  • Using a diagnostic scan tool, perform RCM self-test.
  • Using a diagnostic scan tool, perform BCM self-test.

Were any Diagnostic Trouble Codes (DTCs) retrieved from the RCM or BCM during self-test?
Yes If RCM Diagnostic Trouble Codes (DTCs) were retrieved, do not clear any Diagnostic Trouble Codes (DTCs) until all Diagnostic Trouble Codes (DTCs) have been resolved.
REFER to: Airbag Supplemental Restraint System (SRS) - Vehicles With: Rear Seat Side Airbag (501-20B Supplemental Restraint System, Diagnosis and Testing).
If BCM Diagnostic Trouble Codes (DTCs) were retrieved, diagnose the BCM concern.
REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Diagnosis and Testing).
No CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs). PROVE OUT the SRS . The repair is complete. RETURN the vehicle to the customer.
