Data List Reference Table

The following items can be read by the scan tool from the ASC-ECU input data.

The following items of ECU input data can be read using scan tool.

1. The system is normal.

   Item No.	Check item	Check conditions	Normal conditions
   01	FR wheel speed sensor	Perform a test run of the vehicle.	The speedometer display and the M.U.T.-III display almost agree with each other. (During stop: approximately 0.7 km/h (0.43 mph))

2. System shutdown by ECU

   While ASC-ECU is disabled by the diagnostic function, the scan tool displayed data is different from the actual measurement.
