DTC SUMMARY
MALFUNCTION DESCRIPTION
This DTC indicates that the motor torque execution value does not correspond to the torque command value sent from the hybrid vehicle control ECU to the motor (MG2). The cause of this malfunction may be one of the following:
Area | Main Malfunction Description |
---|---|
Inside of inverter | Inverter with converter assembly internal circuit malfunction |
Hybrid vehicle transaxle assembly |
|
Motor cable (for MG2) |
|
Inverter low-voltage circuit | The connectors are not connected properly |
Hybrid vehicle control ECU | Hybrid vehicle control ECU internal circuit malfunction |
DESCRIPTION

A DTC is stored when the actual motor torque deviates from the motor torque requested by the hybrid vehicle control ECU.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
---|---|---|---|---|---|
P0C1900 | Drive Motor "A" Execution Torque Performance | Motor (MG2) torque execution monitoring malfunction: The difference between the motor torque requested by the motor generator control ECU and actual motor torque is large. (1 trip detection logic) |

MONITOR DESCRIPTION
If the difference between the requested motor torque and the actual motor (MG2) torque exceeds a predetermined value, the motor generator control ECU determines that there is a malfunction in the execution or monitoring of the motor (MG2) torque. Then, the motor generator control ECU will illuminate the MIL and store a DTC.
