April 5, 2026: LEMON Manuals is launched! Read the announcement.

Using SST (M-MDS)

NOTE:
  1. Connect the SST (M-MDS) to the DLC-2.
  2. Turn the ignition switch to ON position.
  3. Measure the PID value.
    • If PID value is not within the specification, follow the instructions in Action column.
      NOTE:
      • The PID/DATA MONITOR function monitors the calculated value of the input/output signals in the PCM. Therefore, an output device malfunction is not directly indicated as a malfunction of the monitored value for the output device. If a monitored value of an output device is out of specification, inspect the monitored value of the input device related to the output control.
