DTC B152F:11 [DASH-ELECTRICAL SUPPLY UNIT]

id0702k8708600

Outline

System malfunction location	Malfunction of circuit of temperature sensor of refrigerant line for electric compressor outlet
Detection condition	•  The dash-electrical supply unit detects a short to ground in the circuit of the temperature sensor of the refrigerant line for the electric compressor outlet.
Fail-safe	•  Fixes the temperature sensor of refrigerant line for electric compressor outlet input value at 150 °C {302 °F} and performs control.
Possible cause	•  Malfunction of connector or terminal of temperature sensor of refrigerant line for electric compressor outlet •  Dash-electrical supply unit connector or terminal malfunction •  Short to ground in signal circuit of temperature sensor of refrigerant line for electric compressor outlet •  Short to ground in ground circuit of temperature sensor of refrigerant line for electric compressor outlet •  Malfunction of temperature sensor of refrigerant line for electric compressor outlet •  Dash-electrical supply unit malfunction

Diagnostic Procedure

Step	Inspection	Results	Action
1	MALFUNCTION OF CONNECTOR OF TEMPERATURE SENSOR OF REFRIGERANT LINE FOR ELECTRIC COMPRESSOR OUTLET •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
2	INSPECT DASH-ELECTRICAL SUPPLY UNIT CONNECTOR FOR MALFUNCTION •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
3	INSPECT SIGNAL CIRCUIT OF TEMPERATURE SENSOR OF REFRIGERANT LINE FOR ELECTRIC COMPRESSOR OUTLET FOR SHORT TO GROUND •  Inspect the applicable circuit for a short to ground. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
4	INSPECT GROUND CIRCUIT OF TEMPERATURE SENSOR OF REFRIGERANT LINE FOR ELECTRIC COMPRESSOR OUTLET FOR SHORT TO GROUND •  Inspect the applicable circuit for a short to ground. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
5	INSPECT TEMPERATURE SENSOR OF REFRIGERANT LINE FOR ELECTRIC COMPRESSOR OUTLET FOR MALFUNCTION •  Inspect the applicable part. (See TEMPERATURE SENSOR OF REFRIGERANT LINE FOR ELECTRIC COMPRESSOR OUTLET INSPECTION [FULL-AUTO AIR CONDITIONER].) •  Is the part normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED •  Install/connect the part removed/disconnected during the troubleshooting procedure. •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Perform the DTC inspection for dash-electrical supply unit. (See DTC INSPECTION.) •  Is the same DTC displayed?	Yes	Refer to the CAN (controller area network) 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 is not resolved, replace the dash-electrical supply unit, then go to the next step. (See DASH-ELECTRICAL SUPPLY UNIT REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)
		No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTCs ARE DISPLAYED •  Perform the DTC inspection. (See DTC INSPECTION.) •  Is a DTC displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
		No	DTC troubleshooting completed.
