DESCRIPTIONS OF MONITOR METHODS
The torque of the drive motor and the starter generator is monitored by the PHEV-ECU, checking that the drive motor and the starter generator are safely controlled.
MONITOR EXECUTION
Continuous

Check Conditions
- The power supply mode of electric motor switch is ON.
- The PHEV-ECU power supply voltage is more than 9.0 volts.
- The absolute value of the command torque of the generator control unit (GCU) is less than 200 Nm/sec.
Judgment Criterion
- When a state where the absolute value of the difference between the command torque of the generator control unit (GCU) and the response torque of the generator control unit (GCU) is larger than 20 Nm continues for 0.5 seconds
OBD-II DRIVE CYCLE PATTERN
- Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 .
PROBABLE CAUSES
Malfunction of the power drive unit (GCU).
