DTC: P0A78 (TC15) Abnormality in inverter system

INFORMATION

Technical description

•

–

<Description of malfunction>

•

Detected an abnormality in the inverter (motor overcurrent).

DTC set condition

(1)

DTC detection condition

•

Control power supply voltage is 8 V or more.

•

Inverter start signal is ON.

•

Three-phase ON control request flag = OFF

•

The motor speed is 375 r/min or more.

(2)

Judgement criteria

•

The state in which the phase currents monitored in control cycles are higher than 415 A is detected continu-
ously for 0.08 seconds.

Reset condition

•

The state in which the phase currents monitored in control cycles are 415 A or less is detected continuously for 0.16
seconds.

Indication, warning or system control regulation when the DTC is set.

•

MIL: ON

•

HV warning light: ON

Symptoms on the vehicle when the DTC is set

<Symptoms on the vehicle due to backup control (fail safe)>

•

–

<Symptoms on the vehicle due to malfunction>

•

The engine may become unable to start. (Note, however, that vehicles equipped with a starter will be started with
the starter.)

•

Idling stop is not available.

•

The regeneration function stops, reducing the feeling of deceleration during deceleration.

Pre-inspection work

•

Check the battery voltage to make sure that there is no abnormality.
