HYBRID / BATTERY CONTROL  PA10 HYBRID CONTROL SYSTEM(for LITHIUM-ION BATTERY)  Drive Start Control  


DESCRIPTION

The drive start control is controlled by the hybrid vehicle control ECU.

If the hybrid vehicle control ECU determines that the shift lever and accelerator pedal are operated abnormally, hybrid system output is restricted and, when necessary, a warning is displayed on the combination meter assembly.

CAUTION / NOTICE / HINT

HINT:

Even if the accelerator pedal position is maintained, the hybrid system output may increase when driving uphill and decrease when driving downhill. This is due to drive start control controlling the hybrid system output, and is not a malfunction.


PROCEDURE

1.PAST ACTIVATION CONFIRMATION
a.

Check if the customer operated the vehicle in a way that would cause the drive start control to operate.

HINT:
