• If DTC P1196 is displayed with DTC P0201, P0202, P0203, P0204, first perform the trouble diagnosis

for DTC P0201, P0202, P0203, P0204. Refer to 

EC-237, "DTC Logic"

.

• If DTC P1196 is displayed with DTC P0335, first perform the trouble diagnosis for DTC P0335. Refer

to 

EC-251, "DTC Logic"

.

• If DTC P1196 is displayed with DTC P0340, first perform the trouble diagnosis for DTC P0340. Refer

to 

EC-255, "DTC Logic"

.

• If DTC P1196 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer

to

.

ECM calculates the target torque based on the engine power request signal and the engine speed request sig-

nal sent from HV ECU.

HV ECU calculates the estimated torque based on the generator torque.

ECM compares the calculated target torque with the estimated torque sent from HV ECU.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-

ing the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

temperature.

2. Turn ignition switch OFF and wait at least 10seconds.

3. Turn ignition switch ON.

4. Turn ignition switch OFF and wait at least 10seconds.

5. Turn ignition switch ON (READY).

6. Select “POOR ENG PWR P1196” of ”ENGINE PERFORMANCE” in “DTC WORK SUPPORT” mode with

CONSULT-III.

7. Touch “START”.

8. Drive vehicle at a speed of 60 km/h (37 MPH) or more until “TESTING” on CONSULT-III changes to

“COMPLETED”. (It will take approximately 10 seconds.)

CAUTION:

Always drive vehicle at a safe speed.

NOTE:

DTC No.
