INSPECTION PROCEDURE 4: The system is not activated when the electric motor switch is pressed.
 
 
 
 
COMMENTS ON TROUBLE SYMPTOM
When the system is not activated with the electric motor switch ON, the selector lever assembly, wire(s), connector(s), the OSS system or the PHEV-ECU may be defective.
noteIf no components respond, diagnose the OSS system. (Refer to GROUP 42B - Troubleshooting <OSS-ECU>, Trouble Symptom Chart )
 
 
 
PROBABLE CAUSES
  • Malfunction of the selector lever assembly
  • Damaged harness or connector
  • The OSS system fails
  • Malfunction of the PHEV-ECU
 
 
 
 
DIAGNOSIS
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.
 
STEP 2. Check the READY (ready to drive) indicator.
Operate the electric motor switch so that the system is ready, and check that the READY indicator illuminates.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope with Intermittent Malfunction ).
Replace the PHEV-ECU (Refer to ).
