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
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
- Turn the power switch on (READY).
- 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.
- Move the shift lever to P, check that the engine is stopped and move the shift lever to N.
- Set the A/C for maximum cooling.
-
Leave the vehicle for a few minutes.
HINT:
When the accelerator pedal is not depressed with the power switch on (READY) and shift lever in P, if "VL-Voltage before Boosting" and the "Hybrid Battery Voltage" is approximately the same after repair, the condition is judged as normal.
- 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 driving pattern again.
PROCEDURE
