HYBRID / BATTERY CONTROL  HYBRID CONTROL SYSTEM  P0D2D1C  Drive Motor "A" Inverter Voltage Sensor Voltage Out of Range  


DTC SUMMARY

MALFUNCTION DESCRIPTION


The hybrid vehicle control ECU detects a VH sensor malfunction.

The cause of this malfunction may be one of the following:

Inverter voltage sensor internal circuit malfunction
·

Voltage sensor malfunction

·

Motor generator control ECU (MG ECU) malfunction

·

Communication (wire harness) malfunction


High voltage system malfunction

Inverter with converter assembly malfunction



Air conditioning system malfunction

Compressor with motor assembly malfunction


DESCRIPTION

For a description of the inverter.

The signal line from the inverter voltage (VH) sensor is connected to the MG ECU, which is built into the inverter with converter assembly.

HINT:

The term "drive motor A" indicates the motor (MG2).

MONITOR DESCRIPTION

The hybrid vehicle control ECU monitors the inverter voltage (VH) sensor signal. If the hybrid vehicle control ECU detects a malfunction of the sensor signal, the hybrid vehicle control ECU interprets this as a VH sensor failure. The hybrid vehicle control ECU will illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN

HINT:
·

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.

Click hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>HYBRID CONTROL SYSTEM>UTILITY

·


1.

Connect the GTS to the DLC3.

2.

Turn the ignition switch to ON and turn the GTS on.

3.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4.

Turn the ignition switch off and wait for 2 minutes or more.

5.

Turn the ignition switch to ON and turn the GTS on.

6.

Turn the ignition switch to ON (READY). [*1]

7.

With the shift lever in D, depress both the accelerator pedal and brake pedal at the same time to raise the "Hybrid/EV Battery SOC" to a sufficient level. [*2]

8.

Move the shift lever to P, check that the engine is stopped and move the shift lever to N. [*3]

9.

Set the A/C for maximum cooling. [*4]

10.

Leave the vehicle for a few minutes. [*5]

HINT:
·

Confirm that the Data List item "Boost Ratio" is 0% when the accelerator pedal is not depressed. Check that the Data List items "VH-Voltage after Boosting" and "Hybrid/EV Battery Voltage" are almost the same.

·

[*1] to [*5] : Normal judgment procedure.

The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.



11.

Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.

12.

Check the DTC judgment result.

HINT:
·

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.




CAUTION / NOTICE / HINT

HINT:
·

P0D2D1C may be output as a result of the malfunction indicated by the DTCs in table below.

(a)

The chart above is listed in inspection order of priority.

(b)

Check DTCs that are output at the same time by following the listed order. (The main cause of the malfunction can be determined without performing unnecessary inspections.)
