MONITOR DESCRIPTION
The hybrid vehicle control ECU assembly monitors the inverter voltage (VH) sensor signal. If the hybrid vehicle control ECU assembly detects a malfunction of the sensor signal, the hybrid vehicle control ECU assembly interprets this as a VH sensor failure. The hybrid vehicle control ECU assembly 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 here
-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- 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 and turn the Techstream on.
- Turn the ignition switch to ON (READY). [*1]
- With the shift lever in D, depress both the accelerator pedal and brake pedal at the same time to raise the "Hybrid Battery SOC" to a sufficient level. [*2]
- Move the shift lever to P, check that the engine is stopped and move the shift lever to N. [*3]
- Set the A/C for maximum cooling. [*4]
-
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 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.
- Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
-
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.
