DTC U2300:56 [BLIND SPOT MONITORING (BSM) SYSTEM]

id09021o066300

Description

Configuration data unmatched with instrument cluster

Detection condition

•  Configuration data of the blind spot monitoring (BSM) control module and instrument cluster are not matched with the ignition switched ON (engine off or on).

Fail-safe

•  Blind spot monitoring (BSM) system is stopped.

Possible cause

•  DTCs are stored in the instrument cluster.

―  Instrument cluster configuration not implemented

―  Instrument cluster internal memory malfunction

•  Instrument cluster configuration data error

•  Blind spot monitoring (BSM) control module (LH) malfunction

Diagnostic Procedure

Step	Inspection		Action
1	VERIFY INSTRUMENT CLUSTER DTCs • Retrieve the instrument cluster DTCs using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].) • Are any DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [INSTRUMENT CLUSTER].)
1		No	Go to the next step.
2	RESET INSTRUMENT CLUSTER CONFIGURATION DATA • Using the M-MDS, perform the instrument cluster configuration (using As-Built data). (See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).) • Clear the DTC for the blind spot monitoring (BSM) control module using the M-MDS. (See CLEARING DTC [BLIND SPOT MONITORING (BSM) SYSTEM].) • Retrieve the blind spot monitoring (BSM) control module DTCs using the M-MDS. (See DTC INSPECTION [BLIND SPOT MONITORING (BSM) SYSTEM].) • Is the same DTC displayed?	Yes	Using the M-MDS, perform the instrument cluster configuration (using As-Built data) again, then go to the next step. (See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).)
2		No	Go to Step 4.
3	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the DTC for the blind spot monitoring (BSM) control module using the M-MDS. (See CLEARING DTC [BLIND SPOT MONITORING (BSM) SYSTEM].) • Retrieve the blind spot monitoring (BSM) control module DTCs using the M-MDS. (See DTC INSPECTION [BLIND SPOT MONITORING (BSM) SYSTEM].) • Is the same DTC displayed?	Yes	Replace the blind spot monitoring (BSM) control module (LH), then go to the next step. (See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION.)
3		No	Go to the next step.
4	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [BLIND SPOT MONITORING (BSM) SYSTEM].)
4		No	DTC troubleshooting completed.
