DTC: P0BEE (TCB6) Abnormality in W-phase current sensor characteristics
INFORMATION
1.
Technical description
•
–
<Description of malfunction>
•
Detected an abnormality (deviation 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.
(2)
Judgement criteria
•
The state in which the value after W-phase current deviation absolute value filtering is larger than (Deviation
threshold value [torque dependent] + Revolution correction item - Offset) is detected continuously for 0.15
second.
3.
Reset condition
•
The following condition continues for 0.3 second:
- When the abnormality is not confirmed, the value after W-phase current deviation absolute value filtering is (Devi-
ation threshold value + Revolution correction item - Offset) or less.
At the same time, the final torque command value is less than 111.2 Nm.
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
