INSPECT REFRIGERANT PRESSURE SENSOR NO.2 FOR MALFUNCTION
• Connect the M-MDS to the DLC-2.
• Switch the main power ON (READY off).
• Turn the A/C off.
• Display the following BECM PIDs using the M-MDS.
(See PID/DATA MONITOR INSPECTION.)
• Wait until the HV_BATT_OUT_REFR_TEMP PID value is above −15 °C {5 °F}.
• Verify the HV_BATT_REFR_PRES PID value.
• Is the HV_BATT_REFR_PRES PID value below 0.55 MPa {5.6 kgf/cm2, 79 psi}?
|
Yes
|
Refer to the CAN (controller area network) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, replace the high voltage battery and perform the repair completion verification 2.
|
No
|
Go to the next step.
|
||
3
|
PERFORM ON-BOARD DIAGNOSTIC FOR ELECTRIC EXPANSION VALVE (COOLING BATTERY)
• Connect the M-MDS to the DLC-2.
• Switch the main power ON (READY on).
• Select the following menu and perform the on-board diagnostics for the electric expansion valve.
• Is [Normal] displayed as the diagnosis result?
|
Yes
|
Go to the next step.
|
No
|
Replace the high voltage battery, then go to the repair completion verification 2.

|
PERFORM ON-BOARD DIAGNOSTIC FOR ELECTRIC EXPANSION VALVE (AIR CONDITIONER)
• Connect the M-MDS to the DLC-2.
• Switch the main power ON (READY on).
• Select the following menu and perform the on-board diagnostics for the electric expansion valve.
• Is [Normal] displayed as the diagnosis result?
|
Yes
|
Perform malfunction diagnosis according to the symptom troubleshooting for [AIR FROM VENTS NOT COLD ENOUGH] of the climate control system.
|
No
|
Replace the heat pump valve component No.1, then go to the repair completion verification 1.
|
||
Repair completion verification 1
|
PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS HIGH VOLTAGE BATTERY
• Clear the DTC recorded in the memory.
(See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
• Perform the DTC inspection for the BECM.
(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.
If the CAN communication is normal, replace the high voltage battery and perform the repair completion verification 2.
|
No
|
Go to the next step.
|
||
Repair completion verification 2
|
VERIFY IF OTHER DTCs 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.
