Internal inverter malfunctionDESCRIPTION
DTC No. | Detection Item |
DTC Detection Condition |
Trouble Area | MIL |
Warning Indicate | Note |
---|---|---|---|---|---|---|
P0BFD62 | Drive Motor "A" Phase U-V-W Current Sensor Signal Compare Failure |
Motor inverter current sensor characteristic malfunction: The value of the total output of the U, V and W phase current sensors exceeds the threshold.*1 (1 trip detection logic) |
| Comes on |
Master Warning: Comes on |
SAE Code: P0BFD |
P1C671F | Drive Motor "A" Phase U-V-W Current Sensor Circuit Intermittent |
The value of the total output of the U, V and W phase current sensors exceeds the threshold detected when DTC P0C7917, P0E5717, P0D3319, P1C5D19, P1C5F19 or P1C5E19 is stored. (1 trip detection logic) |
| Does not come on |
Master Warning: Does not come on |
SAE Code: P1C67 |
HINT:
*1: Under normal conditions, the value of the total output of the U, V and W phase current sensors is approximately 0.
MONITOR DESCRIPTION
If the value of the total output of the U, V and W phase current sensors exceeds a threshold, a malfunction will be detected, the motor generator control ECU will illuminate the MIL and store a DTC.
