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 IPC . 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 IPC sends a configuration data message to the RCM during RCM prove out. During prove-out of each subsequent ignition cycle, the IPC sends configuration data to the RCM and the RCM compares the message to that received during 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 IPC , this DTC reports as a CMDTC . If the RCM reports this DTC on-demand, the configuration data message has not been received from the IPC . |
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 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 IPC . |
Possible Causes
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.
Is DTC U2300:55 or U2300:64 retrieved on-demand?
|
||||
A2 CHECK FOR THE CORRECT IPC (INSTRUMENT PANEL CLUSTER) | ||||
Does the recorded part number match the number listed in the Ford parts catalog?
|
||||
A3 CHECK FOR THE CORRECT RCM (RESTRAINTS CONTROL MODULE) | ||||
Does the recorded part number match the number listed in the Ford parts catalog?
|
||||
A4 CHECK FOR ADDITIONAL RCM (RESTRAINTS CONTROL MODULE) OR IPC (INSTRUMENT PANEL CLUSTER) 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.
Were any Diagnostic Trouble Codes (DTCs) retrieved from the RCM or IPC during self-test?

NOTICE: If the fluid is spilled on the paintwork, the affected area must be immediately washed down with cold water.
Master Cylinder
NOTE: When a new brake master cylinder has been installed, it should be primed to prevent air from entering the system.
NOTE: Make sure the area around the master cylinder cap is clean and free of foreign material.
