DESCRIPTION

From the HV ECU, the ECM receives data such as power output required for the engine (required output), estimated torque produced by the engine (estimated torque), engine RPM of control target (target RPM), whether the engine is in start mode or not. Then, based on the required output and target RPM, the ECM calculates a target torque that is to be produced by the engine and compares it with the estimated torque. If the estimated torque is very low compared with the target torque, or the engine start mode continues for the specific duration calculated by water temperature, an abnormal condition is detected.

MONITOR DESCRIPTION

The ECM and HV control ECU are connected by a communication line called CAN. The ECM sends information on the engine speed and other data to the HV control ECU while the HV control ECU sends the information such as a requirement for the engine power to the ECM using the CAN communication line.
When the communication between the ECM and HV control ECU is normal and the following items becomes specific condition, the ECM will illuminates the MIL and sets a DTC.
(a) Engine speed
(b) Power switch
(c) Target torque
(d) Ratio of target torque against estimated torque
(e) Fuel level

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P3190, P3191 AND/OR P3193)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the power switch ON (IG).

  1. Turn the intelligent tester ON.

  1. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.

  1. Read DTCs.

    HINT:
    If any other codes besides P3190, P3191 and/or P3193 are output, perform troubleshooting for those DTCs first.
