NOTE: When the select lever is shifted while the engine is idling, there will be a certain time elapse or lag before shock is felt. This symptom helps to check the condition of forward clutch and reverse brake.

Perform the test at normal operation CVTF temperature of 60 - 80°C (140 - 176°F).
Be sure to allow one minute or more interval between tests.
Make three measurements and take the average value.

Apply the parking brake.
Start the engine. Check the idle speed. (A/C OFF)
Shift the select lever from "N" to "D" range. Using a stop watch, measure the time elapsed from shifting the lever until the shock is felt.
Time lag standard:

1.2 seconds or less

If "N" → "D" time lag is longer than specified:
- Secondary pressure (line pressure) is too low.
- Forward clutch worn
- Forward clutch piston malfunction
- Control valve body malfunction
- Learning incomplete
In the same manner, measure the time lag when shifting from "N" to "R" range.
Time lag standard:

1.5 seconds or less

If "N" → "R" time lag is longer than specified:
- Secondary pressure (line pressure) is too low.
- Reverse brake worn
- Reverse brake piston malfunction
- Control valve body malfunction
- Learning incomplete

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.

Safety Warning

Time Lag Test: Inspection
