DTC P0A94-589: DC / DC Converter Performance; DTC P0A94-590: DC / DC Converter Performance: Description
WARNING: This page is about a different variant/trim than selected.
The MG ECU uses a voltage sensor that is built into the boost converter to detect pre-boost high voltage (VL) to allow boost control. The boost converter voltage sensor outputs a voltage that varies between 0 and 5 V in accordance with changes in the high voltage. The higher the high voltage, the higher the output voltage. Conversely, the lower the high voltage, the lower the output voltage. The MG ECU monitors the boost converter voltage sensor signal line and detects a malfunction.
| DTC No. | INF Code | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P0A94 | 589 | Open or short to GND in the boost converter voltage (VL) sensor circuit | Inverter with converter assembly |
| P0A94 | 590 | Short to +B in the boost converter voltage (VL) sensor circuit | Inverter with converter assembly |
