- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS 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 GTS on.
- With the ignition switch ON and wait for 5 seconds or more. [*1]
- Turn the ignition switch to ON (READY) and wait for 5 seconds or more. [*2]
- With the brake pedal depressed, depress the accelerator pedal to start the engine. [*3]
- Wait for approximately 10 seconds while depressing the brake pedal and accelerator pedal. [*4]
HINT:
[*1] to [*4]: 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.
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:
- P1CFF62 may be output as a result of the malfunction indicated by the DTCs in table below.
- The chart above is listed in inspection order of priority.
- 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.)
