DTC No.	Detection Item	DTC Detection Condition	Warning Indicate	Memory	Fail-safe Operation	Note
U2300-54	Central Configuration Missing Calibration	Configuration error (data not received)	Not applicable	DTC Stored	Applicable	Drive cycle: Not applicable Self test type: CMDTC self test, OD DTC self test
U2300-55	Central Configuration Not Configured	Configuration error (not configured)	Not applicable	Not applicable	Applicable	Drive cycle: Not applicable Self test type: CMDTC self test, OD DTC self test
U2300-56	Central Configuration Invalid / Incompatible (ISO/SAE reserved)	Configuration error (ineffective/non-interchangeable data read)	Not applicable	DTC Stored	Applicable	Drive cycle: Not applicable Self test type: CMDTC self test, OD DTC self test
U2300-64	Central Configuration Signal plausibility failure	Configuration error (error value read)	Not applicable	DTC Stored	Applicable	Drive cycle: Not applicable Self test type: CMDTC self test, OD DTC self test

DTC Detection Condition	U2300-54: Configuration error (data not received) U2300-55: Configuration error (not configured) U2300-56: Configuration error (ineffective/non-interchangeable data read) U2300-64: Configuration error (error value read)
DTC Detection Condition	Air conditioning amplifier detects configuration data not record or data error
Fail-safe Operation	Sets the configuration value to the fixed value
Trouble Area	HINT: If power from the battery is interrupted, the air conditioning amplifier will go into a non-configured state because the memory for the configuration information is erased. If the ignition is switched ON (engine off) at this time, DTC U2300-55 is detected. Normally, 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 combination meter Air conditioning amplifier malfunction
