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 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)

- 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 Refer to BCM Hardware Testing (Hybrid/Energi) . USE As-Built data when carrying out PMI for the BCM. 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) . 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) . If BCM Diagnostic Trouble Codes (DTCs) were retrieved, diagnose the BCM. Refer to: BODY CONTROL MODULE (BCM) . No CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs). PROVE OUT the SRS. The repair is complete. RETURN the vehicle to the customer.
