Data Monitor

  1. Data monitor list
    1. Turn the ignition switch to OFFOFF and connect the SSM4 to the DLC3.
    2. With IG ON, follow the SSM4 on-screen instructions to check the data monitor.
      CAUTION: Factors including slight margins of error in measurement, differences in measurement environments, and vehicle's time-dependent change may significantly affect the computer data values. Thus it is difficult for the computer data to show reliable standard values (judgment values). Therefore, even if the value is within the standard range, an error may occur.
