INSPECTION MODE PROCEDURE
INSPECTION MODE (for HV Model)
NOTICE:
When operating the vehicle in an inspection mode for an operation such as a speedometer test, a DTC may be stored. Therefore, if the warning light illuminates, check for DTCs using the Techstream and clear the DTCs.
HINT:
If the engine is warmed up and the HV battery is charged, the engine will stop after the vehicle is stopped. If the engine is required to run continuously even after the vehicle is stopped, such as for an ignition timing check, switch to maintenance mode.
(a) The following table shows the types of inspection mode that are available, their purpose and the control that occurs in each mode.
Mode (Display) | Purpose |
Control |
---|---|---|
2WD MAINTENANCE MODE (2WD for measuring Exhaust Gas) |
|
|
2WD CERTIFICATION MODE (2WD for cutting TR(A)C) |
For performing tests using a speedometer tester, two-wheel chassis dynamometer, etc. |
Cancels traction control |
4WD MAINTENANCE MODE (4WD for measuring Exhaust Gas) |
|
|
4WD CERTIFICATION MODE (4WD for cutting TR(A)C) |
For performing tests using a speedometer tester, four-wheel chassis dynamometer, etc. |
Cancels traction control |
(b) Vehicle conditions
(1) Before activating inspection mode, turn the air conditioning off, start the hybrid system with the shift lever in P or with park (P) selected, and check that the engine stops within several seconds after starting (engine warm up check).
(2) Activate the appropriate inspection mode and inspect the vehicle:
Test Item | Mode |
---|---|
Vehicle straight traveling test (side slip inspection) |
2WD MAINTENANCE MODE, 4WD MAINTENANCE MODE or normal mode |
Braking force test | Normal mode |
Speedometer test | 2WD MAINTENANCE MODE or 4WD MAINTENANCE MODE |
Exhaust gas test (idling) |
2WD MAINTENANCE MODE or 4WD MAINTENANCE MODE |
Headlight test | 2WD MAINTENANCE MODE, 4WD MAINTENANCE MODE or normal mode |
(3) Cancel inspection mode immediately after completing the inspection.
NOTICE:
Driving the vehicle without canceling inspection mode may damage the hybrid transaxle or the hybrid transmission.
(c) Precautions when performing speedometer test
CAUTION:
Be sure to perform the test in 2WD MAINTENANCE MODE or 4WD MAINTENANCE MODE.
NOTICE:
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 hybrid transaxle or the hybrid transmission.
(1) Depress the accelerator pedal slowly and gradually accelerate the vehicle. Take a measurement.
(2) After the measurement, use the brakes to gradually decelerate the vehicle.
(d) Special notes for using a chassis dynamometer
CAUTION:
Be sure to perform the test in 2WD MAINTENANCE MODE or 4WD MAINTENANCE MODE.
NOTICE:
Sudden acceleration or deceleration of the vehicle on a chassis dynamometer under minimal load may damage the hybrid transaxle or the hybrid transmission.
(1) Always set an appropriate load before starting the test.

VEHICLE LIFT AND SUPPORT LOCATIONS
PRECAUTIONS ABOUT VEHICLE CONDITION WHEN RAISING VEHICLE
(a) The vehicle must be unloaded before jacking up or raising the vehicle. Never jack up or raise a heavily loaded vehicle.
(b) When removing any heavy components, like the engine, transmission, or transaxle, the vehicle center of gravity will shift. To stabilize the vehicle, place a balance weight in a location that will prevent the vehicle from rolling or shifting, or place a transmission jack under the appropriate jack position at the opposite end of the vehicle.
PRECAUTIONS FOR WHEN USING A 4 POST LIFT
(a) Follow the safety procedures outlined in the lift's instruction manual.
(b) Do not damage the tires or wheels while driving onto the lift.
(c) Use wheel chocks to secure the vehicle.
PRECAUTIONS FOR WHEN USING JACK AND SAFETY STANDS
(a) Work on a level surface. Use wheel chocks at all times.
(b) Use safety stands with rubber attachments as shown in the illustration.
*1 | Rubber Attachment |
- | - |
(c) Set the jack and safety stands exactly under the specified locations on the vehicle.
Never set the jack or safety stands under suspension parts, such as a front lower arm, when jacking up the vehicle.
(d) Do not work on or leave the vehicle supported only by a jack. Be sure to support the vehicle with safety stands.
(e) When jacking up the vehicle, first release the parking brake and move the shift lever to N. (w/o Electronic Shift Lever System)
(f) When jacking up the vehicle, first release the parking brake, then move the shift lever to N and confirm that neutral (N) has been selected. (w/ Electronic Shift Lever System)
(g) When jacking up the entire vehicle:
(1) When jacking up the front wheels first, make sure wheel chocks are behind the rear wheels.
(2) When jacking up the rear wheels first, make sure wheel chocks are in front of the front wheels.
(h) When jacking up only the front or rear wheels of the vehicle:
(1) Before jacking up the front wheels, place wheel chocks on both sides of the rear wheels.
(2) Before jacking up the rear wheels, place wheel chocks on both sides of the front wheels.
(i) When lowering a vehicle that only has its front or rear wheels jacked up.
*a | JACK POSITION |
*b | SUPPORT POSITION - Safety stand - Swing arm type lift - Plate type lift (Front side) |
*c | SUPPORT POSITION - Plate type lift (Rear side) |
*d | VEHICLE CENTER OF GRAVITY (Unloaded Condition) |
(1) Before lowering the front wheels, make sure wheel chocks are in front of the rear wheels.
(2) Before lowering the rear wheels, make sure wheel chocks are behind the front wheels.
PRECAUTIONS FOR WHEN USING A SWING ARM TYPE LIFT
(a) Follow the safety procedures outlined in the lift's instruction manual.
(b) Use swing arms equipped with rubber attachments as shown in the illustration.
(c) Position the vehicle so that its center of gravity is centered on the lift (length of "L" in the illustration should be as short as possible).
(d) Ensure that the rubber cushions or swing arms do not contact the body cladding or lower mouldings.
(e) Be sure to lock the swing arms before raising the vehicle (if equipped with arm locks).
(f) Use the lift to raise the vehicle until the tires are off the ground, then stop the lift and shake the front and rear of the vehicle to make sure that it is stable.
*a | Rubber Attachment |
*b | Center of lift |
*c | VEHICLE CENTER OF GRAVITY (Unloaded Condition) |

(c) Be sure to set the vehicle to the specified position described in the following chart and shown in the following illustration.
Right and left set position | Center the vehicle on the lift. |
Front and rear set position |
|
(d) Ensure that the plate lift or rubber lifting blocks do not contact the body cladding or lower mouldings.
