| DTC Code | DTC Name |
|---|---|
| P0A94-589 | DC / DC Converter Performance |
| P0A94-590 | DC / DC Converter Performance |
DESCRIPTION
The MG ECU, which is built into the inverter with converter assembly, detects pre-boosting high voltage (VL) using the voltage sensor in the boost converter to control boosting. The MG ECU also monitors the boost converter voltage sensor signal line and detects malfunctions.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0A94-589 | Boost converter voltage (VL) signal is stuck (Low) (1 trip detection logic) |
Inverter with converter assembly |
| P0A94-590 | Boost converter voltage (VL) signal is stuck (High) (1 trip detection logic) |
Inverter with converter assembly |
| DTC No. | Data List |
|---|---|
| P0A94-589 | VL-Voltage before Boosting |
| P0A94-590 |
INSPECTION PROCEDURE
Tech Tips
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.
PROCEDURE
-
REPLACE INVERTER WITH CONVERTER ASSEMBLY
Tech Tips
The boost converter voltage (VL) sensor is connected to the MG ECU inside the inverter with converter assembly. If P0A94-589 or P0A94-590 is output, replace the inverter with converter assembly.
