Lexus NX Service Manual / Engine & Hybrid System / 2ar-fxe (hybrid / Battery Control) / Hybrid Control System / High Voltage Fuse (P0A95-400)
DESCRIPTION
The hybrid vehicle control ECU estimates the thermal load of the high voltage fuse. If the accumulated thermal load exceeds the threshold, the hybrid vehicle control ECU will store this DTC.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P0A95-400 | High Voltage Fuse | Accumulated thermal load of the high voltage fuse estimated by the hybrid vehicle control ECU exceeds the threshold. (1 trip detection logic) | Service plug grip | Does not come on | Master Warning Light: Comes on |
CAUTION / NOTICE / HINT
HINT:
- If the service plug grip has been replaced, make sure to perform "High Voltage Fuse Accumulated Load History Reset" and then clear the DTCs.
-
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
- Turn the power switch on (IG) and wait for 5 seconds or more.
