DTC: P0BEE (TCB5) Abnormality in W-phase current sensor characteristics
INFORMATION
1.
Technical description
•
–
<Description of malfunction>
•
Detected an abnormality (offset abnormality) in the motor W-phase current sensor.
2.
DTC set condition
(1)
DTC detection condition
•
Control power supply voltage is 8 V or more.
•
Inverter start signal is ON.
•
(DC voltage - Reverse voltage for determining malfunction of inverter gate blocking function) is larger than 20
V.
(2)
Judgement criteria
•
When one of the following conditions continues for 0.2 second:
- W-phase current sensor value (low resolution Ach or Bch) is larger than 539 LSB.
- W-phase current sensor value (low resolution Ach or Bch) is less than 482 LSB.
3.
Reset condition
•
When one of the following conditions continues for 0.4 second:
- W-phase current sensor value (low resolution Ach or Bch) is 539 LSB or less.
- W-phase current sensor value (low resolution Ach or Bch) is 482 LSB or more.
4.
Indication, warning or system control regulation when the DTC is set.
•
MIL: ON
•
HV warning light: ON
5.
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.
6.
Pre-inspection work
•
Check the battery voltage to make sure that there is no abnormality.
7.
After-inspection work
•
Clear the recorded DTC.
•
Check that no DTC is detected after test-driving the vehicle.
8.
Estimated failure factors
•
Malfunction of inverter
