STEP 1. Using scan tool (M.U.T.-IIISE), check the data list. <PHEV-ECU>
Check whether the items listed below of the ones, which satisfy the data list reference table [Scan tool (M.U.T.-IIISE) display or normal condition] (Refer to ).- Item No.1: Power SW signal
- Item No.2: Power SW(ST) signal
- Item No.83: Control power supply SNS.voltage
- Item No.235: OBC connection judgment
- Item No.301: Battery Total voltage
- Item No.302: Condenser voltage
- Item No.303: Shift position(control value)
- Item No.365: SOC for display
Is the check result normal?
Go to Step 2. : PHEV-ECU Trouble symptom inspection procedure 1: PHEV-ECU power supply system malfunction (Refer to ). : Check the wiring harness wires and repair if necessary.
: PHEV-ECU Trouble symptom inspection procedure 1: PHEV-ECU power supply system malfunction (Refer to ). : Check the wiring harness wires and repair if necessary (CNCT and CNIG lines between the PHEV-ECU connector and the normal charging connector).
: Diagnose the BMU when the total battery voltage is low.
: Shut down the high-voltage system (the READY indicator goes off) and wait for at least five minutes. Diagnose the MCU when the condenser voltage is high.
: Check the wiring harness wires and repair if necessary. [SFV, SLS, SFS, SFG, SFGS, SFSS, SLSS and SFVS lines between the PHEV-ECU connector and the selector lever (Joystick type)].
: If 0% or less is displayed, charge the main battery.
