Logic Flow Chart
 
 
Check Condition A
  • The PHEV-ECU power supply voltage is 9.0 volts or more.
  • EV power source relay drive signal is ON
  • The accelerator pedal position sensor (APPS) (main) voltage is between 0.3 volt and 4.82 volts.
  • The accelerator pedal position sensor (APPS) (sub) voltage is between 0.15 volt and 2.41 volts.
Check Condition B
  • The PHEV-ECU power supply voltage is 9.0 volts or more.
  • The power supply mode of the electric motor switch is ON.
  • The accelerator pedal position sensor (APPS) (main) voltage is between 0.3 volt and 4.82 volts.
  • The accelerator pedal position sensor (APPS) (sub) voltage is between 0.15 volt and 2.41 volts.
Judgment Criterion A
  • The voltage deviation between the accelerator pedal position sensor (APPS) (main) and accelerator pedal position sensor (APPS) (sub) is more than the deviation error threshold voltage for 0.5 second or more.
Judgment Criterion B
  • The voltage deviation between the accelerator pedal position sensor (APPS) (main) and accelerator pedal position sensor (APPS) (sub) is more than the deviation error threshold voltage for 0.2 second or more.

  • Malfunction of the PHEV-ECU
 
 
DIAGNOSIS
Required Special Tools:
  • MB992744: Vehicle communication interface-Lite (V.C.I.-Lite)
  • MB992745: V.C.I.-Lite main harness A
  • MB992747: V.C.I.-Lite USB cable short
  • MB992748: V.C.I.-Lite USB cable long
  • MB991223: Wiring harness set
  • MB992006: Extra fine probe
1.Check of short to ground circuit and open circuit in accelerator pedal position sensor 1 system line between PHEV-ECU and accelerator pedal
(1) Check the following lines for short to ground circuit.
  • APV1line
  • APS1line
(2) Check the following lines for open circuit.
  • APV1line
  • APS1line
  • APG1line
Is the check result normal?
Repair the connector(s) or wiring harness. Then,
 
2.Check of short to ground circuit and open circuit in accelerator pedal position sensor 2 system line between PHEV-ECU and accelerator pedal
(1) Check the following lines for short to ground circuit.
  • APV2line
  • APS2line
(2) Check the following lines for open circuit.
  • APV2line
  • APS2line
  • APG2line
Is the check result normal?
Repair the connector(s) or wiring harness. Then,
 
3.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Replace the accelerator pedal (Refer to Engine Control - Accelerator Pedal ACCELERATOR PEDAL REMOVAL AND INSTALLATION), Then go to .
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).
 
4.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Replace the PHEV-ECU (Refer to PHEV-ECU REMOVAL AND INSTALLATION). Then,
The procedure is complete.
 
5.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Retry the troubleshooting.
The procedure is complete.
