HYBRID CONTROL SYSTEM, Diagnostic DTC:P0A94-589, P0A94-590
| DTC Code | DTC Name |
|---|---|
| P0A94-589 | DC / DC Converter Performance |
| P0A94-590 | DC / DC Converter Performance |
DESCRIPTION
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 MG ECU monitors the boost converter voltage sensor signal line and detects the following malfunctions.
| 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 |
PROCEDURE
-
REPLACE INVERTER WITH CONVERTER ASSEMBLY
-
Replace the inverter with converter assembly (See page for LHD, Click here for RHD).
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.
