The motor generator control ECU (MG ECU) uses an inverter voltage sensor, which is built into the inverter, to detect boosted high voltage (VH) and allow control of the voltage boost.
The inverter voltage sensor outputs voltage that fluctuates between 0 to 5 V according to changes in VH.
The motor generator ECU monitors the inverter voltage sensor and detects the following malfunctions.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate | Note |
|---|---|---|---|---|---|---|
| P0D2D16 | Drive Motor "A" Inverter Voltage Sensor(VH) Circuit Voltage Below Threshold | Inverter voltage (VH) signal is stuck low:
DTC stored when the VH sensor signal is excessively low. (1 trip detection logic) |
Inverter with converter assembly | Comes on | Master Warning:
Comes on |
SAE Code:
P0D2F |
| P0D2D17 | Drive Motor "A" Inverter Voltage Sensor(VH) Circuit Voltage Above Threshold | Inverter voltage (VH) signal is stuck high:
DTC stored when the VH sensor signal is excessively high. (1 trip detection logic) |
Inverter with converter assembly | Comes on | Master Warning:
Comes on |
SAE Code:
P0D30 |
| P0D2D1F | Drive Motor "A" Inverter Voltage Sensor(VH) Circuit Intermittent | An excessively high or low voltage signal is output from the inverter voltage sensor (VH) when DTC P0C7917, P0E5717, P0D3319, P1C5D19, P1C5F19 or P1C5E19 is stored.
(1 trip detection logic) |
Inverter with converter assembly | Does not come on | Master Warning:
Does not come on |
SAE Code:
P0D31 |
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.
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
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 (READY) and wait for 5 seconds or more. [*1]
[*1]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
Check the DTC judgment result.
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 the normal judgment procedure again.
