DTC U2300:64 [APPROACHING VEHICLE AUDIBLE SYSTEM DEVICE]

id0902y0138600

Outline

System malfunction location	Configuration data unmatched with body control module (BCM)
Detection condition	•  The approaching vehicle audible system device receives the body control module (BCM) configuration data that is impossible based on the combination of the software and hardware.
Fail-safe	•  Approaching vehicle alert sound is generated at maximum volume
Possible cause	Note •  To correctly write the configuration data sent from the body control module (BCM) to the approaching vehicle audible system device, 30 s or more have to be elapsed since the main power is switched ON (READY off or on). •  DTCs are stored in the body control module (BCM). ―  Body control module (BCM) configuration not implemented ―  Body control module (BCM) internal memory malfunction •  Body control module (BCM) configuration data error •  Configuration procedure was not completed properly. •  Approaching vehicle audible system device removed from other vehicle is being used •  Approaching vehicle audible system device malfunction

Diagnostic Procedure

Step	Inspection	Results	Action
1	VERIFY BODY CONTROL MODULE (BCM) DTCs •  Perform the DTC inspection for the body control module (BCM). (See DTC INSPECTION.) •  Is a DTC displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [BODY CONTROL MODULE (BCM) (E)].)
		No	Go to the next step.
2	VERIFY REPLACEMENT RECORD OF APPROACHING VEHICLE AUDIBLE SYSTEM DEVICE •  Before performing the troubleshooting diagnostic procedure this time, verify if the approaching vehicle audible system device was replaced. •  Was the approaching vehicle audible system device replaced?	Yes	After re-implementing the required servicing when replacing the approaching vehicle audible system device in accordance with approaching vehicle audible system device removal/installation, perform the repair completion verification. (See APPROACHING VEHICLE AUDIBLE SYSTEM (AVAS) DEVICE REMOVAL/INSTALLATION.)
		No	Go to the next step.
3	RESET CONFIGURATION DATA FOR BODY CONTROL MODULE (BCM) •  Using the M-MDS, perform the body control module (BCM) configuration. (See CONFIGURATION.) •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Switch the main power ON (READY off or on) and wait for 30 s or more. •  Perform the DTC inspection for the approaching vehicle audible system device. (See DTC INSPECTION.) •  Is the same Pending DTC present?	Yes	Perform the body control module (BCM) configuration again using the M-MDS and perform the repair completion verification. (See CONFIGURATION.)
		No	Go to repair completion verification 2.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Switch the main power ON (READY off or on) and wait for 30 s or more. •  Perform the DTC inspection for the body control module (BCM). (See DTC INSPECTION.) •  Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [L.H.D. (E)].) (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].) If the CAN communication is normal, perform the diagnosis from Step 1. •  If the malfunction recurs, replace the approaching vehicle audible system device, then go to the next step. (See APPROACHING VEHICLE AUDIBLE SYSTEM (AVAS) DEVICE REMOVAL/INSTALLATION.)
		No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTC IS DISPLAYED •  Perform the DTC inspection. (See DTC INSPECTION.) •  Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
		No	DTC troubleshooting completed.
