Scan Tool Testing and Procedures

PID/DATA MONITOR INSPECTION [GF4A-EL]
1. Connect the SSTs (NGS tester) to the DLC-2.
2. Turn the ignition switch to ON.
3. Select the "PID/DATA MONITOR AND RECORD" function on the SSTs (NGS tester) display and press TRIGGER.
4. Select the appropriate PID on the SSTs (NGS tester) display and press START.
5. Measure the PID value.

Note The PID/DATA MONITOR function monitors the calculated value of the input/output signals in the PCM. Therefore, if a monitored value of an output device is out of specification, it is necessary to inspect the monitored value of the input device related to the output device control. Since an output device malfunction is not directly indicated as a malfunction of the monitored value for the output device, it is necessary to inspect the output device individually using the simulation function, etc.
