id0102i0002600

System malfunction location	•  U2300:54: Configuration error (data not received) •  U2300:55: Configuration error (no configuration) •  U2300:56: Configuration error (Ineffective/non-interchangeable data read) •  U2300:64: Configuration error (error value read)
Detection condition	•  The vehicle control module (V/C-module) detects configuration setting failure.
Fail-safe	•  Inhibits the mazda radar cruise control (MRCC) system control •  Inhibits the smart brake support (SBS) system control •  Inhibits the distance recognition support system (DRSS) control
Possible cause	Note •  If the vehicle control module (V/C-module) is replaced with a new one, the configuration is re-performed within 6 s after the ignition is switched ON (engine off). •  After performing the configuration, DTC U2300:55 will be cleared if the ignition is switched ON (engine off) after the ignition is switched off. •  Module configuration procedure was not completed properly •  Correct data cannot be received from instrument cluster •  Vehicle control module (V/C-module) malfunction
System wiring diagram	•  Not applicable

Diagnostic Procedure

Step	Inspection		Action
1	RECORD THE CAR CONFIGURATION DATA •  Switch the ignition ON (engine off) and wait for 6 s or more. •  Switch the ignition off. •  Switch the ignition ON (engine off).		Go to the next step.
2	PERFORM DTC INSPECTION FOR VEHICLE CONTROL MODULE (V/C-MODULE) •  Clear vehicle control module (V/C-module) DTCs using the M-MDS. (See CLEARING DTC [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Switch the ignition ON (engine on). •  Perform the vehicle control module (V/C-module) DTC inspection using the M-MDS. (See DTC INSPECTION [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, go to the next step.
		No	Go to Step 5.
3	PERFORM DTC INSPECTION FOR INSTRUMENT CLUSTER •  Perform the instrument cluster DTC inspection using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].) •  Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER].) After repairing the instrument cluster, perform the instrument cluster configuration. (See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).) Then go to the next step.
		No	Go to the next step.
4	VERIFY THAT REPAIRS HAVE BEEN COMPLETED •  Clear vehicle control module (V/C-module) DTCs using the M-MDS. (See CLEARING DTC [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Switch the ignition ON (engine on). •  Perform the vehicle control module (V/C-module) DTC inspection using the M-MDS. (See DTC INSPECTION [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Is the same DTC present?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the vehicle control module (V/C-module). (See VEHICLE CONTROL MODULE (V/C-MODULE) REMOVAL/INSTALLATION [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].) Go to the next step.
		No	Go to the next step.
5	VERIFY THAT NO OTHER DTCs ARE PRESENT •  Verify other DTCs displayed. •  Are any other DTCs output?	Yes	Perform the corresponding DTC inspection.
		No	DTC troubleshooting completed.
