TROUBLE JUDGMENT
Check Condition
  • The heater PHEV A/C amp. power supply voltage is between 10 and 16 volts.
  • The A/C compressor voltage is between 215 volts and 445 volts.
Judgment Criterion
  • The absolute value of the difference between the A/C compressor input voltage value and the drive battery voltage value remains 35 volts or more for 2 seconds.
 
 
OBD-II DRIVE CYCLE PATTERN
 
 
PROBABLE CAUSES
  • Malfunction of CAN bus lines (HV1-CAN)
  • Malfunction of LIN bus lines
  • Malfunction of PHEV A/C amp.
  • Malfunction of A/C compressor
 
 
DIAGNOSIS PROCEDURE
1.M.U.T.-III SE CAN bus diagnosis
Use M.U.T.-III SE to diagnose the CAN bus line.
Is the inspection result normal?
Repair the CAN bus line. (Trouble Diagnosis Flow Chart)
 
2.M.U.T.-III SE other DTC
Check whether the PHEV A/C amp. sets the following DTCs related.
  • DTC No. U1D21-87
  • DTC No. U1D24-87
  • DTC No. U2144-87
Are the DTCs set?
Troubleshoot the set DTCs.
 
3.Check the high voltage harness and connectors
danger
(1) Pull out the service plug to shut off the high voltage supplied to the high voltage system.
(2) Visually check for damage and looseness of the following parts
  • High voltage harness A/C compressor side
  • High voltage connector A/C compressor side
  • High voltage harness power drive unit side
  • High voltage connector power drive unit side
Is the inspection result normal?
Reinsert the service plug,
Repair or replace the high voltage harness and connectors.
 
4.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 4 OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Replace PHEV A/C amp. Refer to Removal and Installation. then
The trouble can be an intermittent malfunction. Refer to General Information - How to Use Troubleshooting/Inspection Service Points, How to Cope with Intermittent Malfunctions HOW TO COPE WITH INTERMITTENT MALFUNCTIONS.
 
5.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 4 OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Replace A/C compressor Refer to Removal and Installation.
