DTC SUMMARY
MALFUNCTION DESCRIPTION
These DTCs indicate that the current sensor value is abnormal. The cause of this malfunction may be one of the following:
DESCRIPTION
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
---|---|---|---|---|---|
P0DFA62 | Generator Phase U-V-W Current Sensor Signal Compare Failure | Generator 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 Light: Comes on |
P1C691F | Generator 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, P0D3319, P0E5717, P1C5D19 or P1C5F19 is stored. (1 trip detection logic) |
| Does not come on | Master Warning Light: Does not come on |
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.

Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
*a | Without waiting for 10 minutes |
NOTICE:
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.
