Using SST (NGS Tester)

POWERTRAIN CONTROL MODULE (PCM) INSPECTION

CAUTION: The PCM terminal voltages vary with change in measuring conditions and vehicle conditions. Always carry out a total inspection of the input systems, output systems, and PCM to determine the cause of trouble. Otherwise, a wrong diagnosis will be made.

Using the SST (NGS Tester)

1. In the passenger compartment, connect the SSTs (NGS Tester) to the data link connector.
2. Referring to the NGS Tester instruction manual, select "PID/DATA MONITOR AND RECORD" and press "TRIGGER".

CAUTION: The "PID/DATA MONITOR AND RECORD" function is to monitor the the calculation value of the input/output signals in the PCM. Deviation in the value does not always indicate malfunction in the related devices. For inspection of the input/output signals other than in the link monitor table, check voltage at the applicable PCM terminal by using the SST (104 Pin Breakout Box).

3. Press Clear to clear previously selected items. (A list of item descriptions appears on the screen.)
4. Select items necessary and press START.
5. Carry out inspection referring to PID/DATA MONITOR table.
6. If normal output signal cannot be detected when all input signals are normal, replace the PCM.

PID/DATA MONITOR ITEM TABLE

NOTE: The following PIDs may display on the NGS tester, but they are not used for inspection, because the devices are not applied for in this model.
