P0BFE62 |
Drive Motor "B" Phase U-V-W Current Sensor Signal Compare Failure |
Rear 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 |
|
P1C681F |
Drive Motor "B" 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, P1C5D19, P1C5F19 or P1C5E19 is stored. (1 trip detection logic) |
|
Does not come on |
Master Warning: 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.
CONFIRMATION DRIVING PATTERN
HINT:
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for 2 minutes or more.
- Turn the ignition switch to ON and turn the Techstream on.
- Turn the ignition switch to ON (READY).
- Move the shift lever to D, and then accelerate until the vehicle speed is 20 km/h (12.5 mph) and the accelerator position is approximately 25%.
- Enter the following menus: Powertrain / Rear Motor Generator / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.

CAUTION / NOTICE / HINT
CAUTION:
-
Before the following operations are conducted, take precautions to prevent electric shock by turning the ignition switch off, wearing insulated gloves, and removing the service plug grip from HV battery.
- Inspecting the high-voltage system
- Disconnecting the low voltage connector of the inverter with converter assembly
- Disconnecting the low voltage connector of the HV battery
-
To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.
-
After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
-
After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

HINT:
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 ignition 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.
