Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 Techstream and clear the DTCs.
HINT:
If the engine is warmed up and the 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 mode 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 park (P) is selected
- 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 park (P) selected, and check that the engine stops within several seconds after starting (engine warm up check).
- Activate the appropriate inspection mode and inspect the vehicle. The shift state for each test is as follows:
Test Item Mode Shift State 1. Vehicle straight travelling test (side slip inspection) Maintenance mode or normal mode D 2. Braking force test Maintenance mode N 3. Speedometer test Maintenance mode D 4. Exhaust gas test (idling) Maintenance mode P 5. Headlight test Maintenance mode or normal mode P - Cancel inspection mode immediately after completion of inspection.NOTE:
