.
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.
