REPAIR INSTRUCTION INSPECTION MODE PROCEDURE

INSPECTION MODE

Note

When the vehicle is run in inspection mode for an operation such as a speedometer test, a DTC may be set. Therefore, if the warning light comes on, after canceling inspection mode, check for DTCs using the GTS and clear the DTCs.

Tech Tips

If the engine is warmed up and the HV battery is charged, the engine of the vehicle will stop after the vehicle stops. For example, if the engine is required to run continuously even after the vehicle stops, such as for an ignition timing check, switch to maintenance mode.

The following table shows the types of inspection modes that are available, their purpose and the control that occurs in each mode.

Mode (Display)	Purpose	Control
MAINTENANCE MODE (2WD for measuring Exhaust Gas)	Inspection of ignition timing etc. when performing engine maintenance, idle speed exhaust emissions testing (CO, HC), etc. Tests using a speedometer tester, two-wheel chassis dynamometer, etc.	Keeps the engine idling when the shift lever in P position Cancels traction control
CERTIFICATION MODE (2WD for cutting TRC)	Tests using a speedometer tester, two-wheel chassis dynamometer, etc.	Cancels traction control

MAINTENANCE MODE

(2WD for measuring Exhaust Gas)

Inspection of ignition timing etc. when performing engine maintenance, idle speed exhaust emissions testing (CO, HC), etc.
Tests using a speedometer tester, two-wheel chassis dynamometer, etc.

Keeps the engine idling when the shift lever in P position
Cancels traction control

CERTIFICATION MODE

(2WD for cutting TRC)

Tests using a speedometer tester, two-wheel chassis dynamometer, etc.

Cancels traction control

Vehicle conditions

Before activating inspection mode, turn the air conditioning off, start the hybrid system with the shift lever in P position, and check that the engine stops within several seconds after starting (engine warm up check).

Activate the appropriate inspection mode and inspect the vehicle:

Test Item	Mode
1. Vehicle straight travelling test (side slip inspection)	Maintenance mode or normal mode
2. Braking force test	Normal mode
3. Speedometer test	Maintenance mode
4. Exhaust gas test (idling)	Maintenance mode
5. Headlight test	Maintenance mode or normal mode

Cancel inspection mode immediately after completion of inspection.

Note

Driving the vehicle without canceling inspection mode may damage the transaxle.

Special notes for speedometer test

CAUTION:

Be sure to perform the test in maintenance mode.

Note

Do not perform rapid starting or quick acceleration on a speedometer tester. If rapid starting or quick acceleration is performed on a speedometer tester, damage may occur to the transaxle.
1. Depress the accelerator pedal slowly and gradually accelerate the vehicle. Make a measurement.
2. After the measurement, use the brakes to gradually decelerate the vehicle.
Special notes for using a chassis dynamometer
1. Always set an appropriate load before starting the test.
  
  Note
  
  Sudden acceleration or deceleration of the vehicle on a chassis dynamometer under minimal load may damage the transaxle.
Activating maintenance mode (Not using the GTS)
1. Perform the following steps from (A) through (D) in 60 seconds.
  1. Turn the ignition switch to ON (IG). (Step A)
  2. Fully depress the accelerator pedal twice with the shift lever in P position. (Step B)
  3. Fully depress the accelerator pedal twice with the shift lever in N position. (Step C)
  4. Fully depress the accelerator pedal twice with the shift lever in P position. (Step D)
2. *1 Hybrid System Warning Light (Blinking)
  
  for Segment Display Type:
  1. Check that the hybrid system warning light in the combination meter blinks at 1 second intervals.
3. for TFT Display Type:
  1. Check that "MAINTENANCE MODE" is displayed on the multi-information display.
4. Start the engine by turning the ignition switch to ON (READY) while depressing the brake pedal.
  
  Tech Tips
  
  The idle speed in maintenance mode is approximately 1000 rpm with the shift lever in P position. The engine speed increases to 1500 rpm when the accelerator pedal is depressed midway with the shift lever in P position. When the accelerator pedal is depressed more than midway, or when the accelerator pedal is fully depressed, the engine speed increases to approximately 2500 rpm.
Activating maintenance mode (Using the GTS)
1. Connect the GTS to the DLC3.
2. Turn the ignition switch to ON (IG).
3. Turn the GTS on.
4. Enter following menus: Powertrain / Hybrid Control / Utility / Inspection Mode - 2WD for measuring Exhaust Gas.
5. *1 Hybrid System Warning Light (Blinking)
  
  for Segment Display Type:
  1. Check that the hybrid system warning light in the combination meter blinks at 1 second intervals.
6. for TFT Display Type:
  1. Check that "MAINTENANCE MODE" is displayed on the multi-information display.
7. Start the engine by turning the ignition switch to ON (READY) while depressing the brake pedal.
  
  Tech Tips
  
  The idle speed in maintenance mode is approximately 1000 rpm with the shift lever in P position. The engine speed increases to 1500 rpm when the accelerator pedal is depressed midway with the shift lever in P position. When the accelerator pedal is depressed more than midway, or when the accelerator pedal is fully depressed, the engine speed increases to approximately 2500 rpm.
Activating certification mode (Not using the GTS)
1. Perform the following steps from (A) through (D) in 60 seconds.
  1. Turn the ignition switch to ON (IG). (Step A)
  2. Fully depress the accelerator pedal three times with the shift lever in P position. (Step B)
  3. Fully depress the accelerator pedal three times with the shift lever in N position. (Step C)
  4. Fully depress the accelerator pedal three times with the shift lever in P position. (Step D)
2. *1 Hybrid System Warning Light (Blinking)
  
  for Segment Display Type:
  1. Check that the hybrid system warning light in the combination meter blinks at 2 second intervals.
3. for TFT Display Type:
  1. Check that "CERTIFICATION MODE" is displayed on the multi-information display.
4. Start the engine by turning the ignition switch to ON (READY) while depressing the brake pedal.
Activating certification mode (Using the GTS)
1. Connect the GTS to the DLC3.
2. Turn the ignition switch to ON (IG).

Deactivating inspection mode
1. Turn the ignition switch off. The hybrid system turns off simultaneously.
  Note
  - If a DTC is set during inspection mode, the hybrid system warning light will illuminate and a warning message will appear on the multi-information display.
  - When the hybrid system warning light and the warning message illuminate during inspection mode, cancel inspection mode, and check for DTC(s).
  - Driving the vehicle without canceling inspection mode may damage the transaxle.
