Inspection Mode

HINT:

• The PRIUS' engine automatically stops if the vehicle is stopped, the engine is warmed up, the battery is well charged, and A/C compressor operation is not being used. Activate inspection mode when continuous operation of the engine is required.
• The PRIUS has a motor TRAC function. When the wheel speed of the front wheels exceeds that of rear wheels, the wheel speed of the front wheels is restrained. It is necessary to activate inspection mode and deactivate the motor TRAC function when turning only the front wheels using a speedometer tester.

1. Vehicle conditions
   1. Before activating inspection mode, turn the air conditioning off, start the engine with the selector lever in the P position, and check that the engine stops within several seconds after starting (engine warm up check).
   2. Activate inspection mode and inspect the vehicle. The shift position for each test is as follows:
      INSPECTION MODE OF SHIFT POSITION
      
      

      Test item	Shift position	Inspection mode
      1. Vehicle straight travelling test (side slip inspection)	D	ON or OFF
      2. Breaking force test	N	ON or OFF
      3. Speed meter test	D	ON
      4. Exhaust gas test (idling)	P	ON
      5. Headlight test	P	ON or OFF

   3. Reset inspection mode immediately after completion of inspection.
      NOTE: Driving the vehicle without resetting inspection mode may damage the transaxle.
2. Special notes for speedometer test
   NOTE: Do not use the speedometer tester to perform rapid starting or quick acceleration/deceleration without first setting the proper load on the vehicle. Failing to set the load may damage the transaxle.
   1. Depress the accelerator pedal slowly and gradually accelerate the vehicle. Make a measurement.
   2. After the measurement, use the brake to gradually decelerate the vehicle.
3. Special note for using the chassis dynamometer

   Always set an appropriate load before starting the test.

   2. Fully depress the accelerator pedal twice with the transmission in the P position.
   3. Fully depress the accelerator pedal twice with the transmission in the N position.
   4. Fully depress the accelerator pedal twice with the transmission in the P position.
   5. Check that the HV system warning lamp flashes on the multi-information display.
   6. Start the engine by pushing the power switch, depressing the brake pedal.

   Activating inspection mode (Using the hand-held tester)

   1. Connect the hand-held tester to the DLC3.
   2. Turn the power switch ON (IG).
   3. Turn the hand-held tester ON.
   4. Select the following menu items: DIAGNOSIS / OBD/MOBD / HV ECU / ACTIVE TEST / INSPECTION MOD1 /ON.
   5. Check that the HV system warning flashes on the multi-information display and the master warning lamp is illuminated in the combination meter.

   NOTE:

   • The idling speed in inspection mode is approximately 1,045 RPM. The engine speed increases to 1,500 RPM if the accelerator pedal is depressed by less than 60%. If the accelerator pedal is depressed by more than 60%, the engine speed increases to 2,500 RPM.
   • If a DTC is set during inspection mode, the master warning lamp and the error warning lamp illuminate on the multi-information display.
   • When the master warning lamp illuminates during inspection mode, deactivate inspection mode, and check a DTC(s).
   • Driving the vehicle without deactivating inspection mode may damage the transaxle.
