Logic Flow Chart
Check Conditions
  • The A/C compressor assembly power supply voltage is between 10 and 16 volts.
Judgment Criterion <DTC P1F0D>
  • Change the battery cooling evaporator temperature sensor voltage is more than 0.07 volt [196°C (385°F)] for 3 seconds.
Check Conditions <DTC P1F0E>
  • Change the battery cooling evaporator temperature sensor voltage is more than 4.92 volts [-55°C (67°F)] for 3 seconds.
 
 
OBD-II DRIVE CYCLE PATTERN
  • Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 3 .
 
 
PROBABLE CAUSES
  • Malfunction of the CAN bus
  • Malfunction of the heater controller assembly (A/C-ECU)
  • Malfunction of the PHEV-ECU.
 
 
DIAGNOSIS
STEP 1. Using scan tool (M.U.T.-IIISE), check whether the other DTC is set.
Scan tool (M.U.T.-IIISE) other system DTC [heater controller assembly (A/C-ECU)] (Refer to ).
Is the DTC set?
Troubleshoot for the relevant DTC. Then go to Step 3.
Go to Step 2.
 
STEP 2. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 3 .
(2) Check if the DTC is set.
Is the DTC set?
Replace the PHEV-ECU (Refer to GROUP 54Da - PHEV-ECU ). Then go to Step 3.
The procedure is complete.
 
STEP 3. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 3 .
(2) Check the DTC.
Is the DTC set?
Retry the troubleshooting.
The procedure is complete.
