Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in REFER to Service Information for information about these practices.
Refer to SUPPLEMENTAL RESTRAINT SYSTEM , Supplemental Restraint System for schematic and connector information.
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 RCM prove out. During prove-out at the beginning of each subsequent ignition cycle, the BCM sends configuration data to the RCM and the RCM compares the message to the message that was received during the very first ignition cycle.
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| 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 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 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. |
