WARNING:
When performing Inspection Mode I on a public road, pay sufficient attention to the traffic condition and give the highest priority to safe driving.
CAUTION:
Be careful of the state of the battery when performing the inspection mode I consecutively. Performing the inspection mode I consecutively without the engine running may cause a low battery voltage and battery discharge.
NOTE:
- If it is necessary to perform inspection mode I consecutively, drive the vehicle under the following conditions to release accumulated evaporating gas. Performing the inspection mode I consecutively without starting the engine causes a large amount of evaporating gas to accumulate in the canister, which hinders an accurate diagnosis.
- After engine is warmed up
- Drive for 10 minutes or more at a speed of 48 km/h (30 MPH) or more (duration of drive can be an accumulation)
- To obtain an accurate diagnostic result, perform the procedures according to the following points.
- Do not refuel gas immediately before performing inspection mode I. There will be a large amount of evaporating gas immediately after refuel, which may cause a less accurate diagnostic performance.
- Do not shake the vehicle while performing inspection mode I. Shaking the vehicle causes evaporating gas to increase inside the fuel tank, which may cause a less accurate diagnostic performance.
- Do not perform any service operation including installation or removal of parts or connectors while performing inspection mode I. Performing service operation could affect on the functions of related parts, which may cause a less accurate diagnostic performance.
- Perform MODE $08 when using a general scan tool.
