CHECK SPEEDOMETER

NOTICE:

  • If the tire size or tire inflation pressure is not within the specified range, or the tires are excessively worn, the speedometer indication error will increase. Therefore, make sure to perform this inspection after checking that the tire size, tire inflation pressure and tire wear are in the specified range.
  • When the electronically controlled brake system is malfunctioning, an accurate vehicle speed signal may not be able to be obtained. Therefore, make sure to confirm that the electronically controlled brake system is not malfunctioning before performing this procedure.

HINT:

The indicated value of the speedometer has an allowable range. Therefore, even when the combination meter assembly is not malfunctioning, the actual vehicle speed and the indicated value speed may not match.

(a) Read the vehicle speed of the Data List item of the electronically controlled brake system and compare the indicated values of the speedometer with the following table.

CHECK TACHOMETER

NOTICE:

When the SFI system is malfunctioning, an accurate engine speed signal may not be able to be obtained. Therefore, make sure to confirm that the SFI system is not malfunctioning before performing this procedure.

HINT:

The indicated value of the tachometer has an allowable range. Therefore, even when the combination meter assembly is not malfunctioning, the actual engine speed and the indicated value speed may not match.

(a) Read the engine speed of the Data List item of the SFI system and compare the indicated values of the tachometer with the following table.

Data List: engine speed value (rpm)

Acceptable Range (rpm)
( ) is for Reference
