Component Inspection

CAUTION:
- The PID values 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. if this Is
not done, a wrong diagnosis will be made.




1. In the passenger compartment, connect the SST (NGS tester) to the
data link connector-2 located under the driver side dashboard.




2. Referring to the NGS tester operational manual, select the "PID/DATA MONITOR AND RECORD" function.
3. Referring to the PID/DATA MONITOR table, inspect each PCM input/output signal.

NOTE:
- The "PID/DATA MONITOR AND RECORD" function is to monitor the calculation value of input/output signals in the PCM. Deviation in the value does not always indicate malfunction in the related input/output devices (sensors and solenoids).

4. If normal output signal cannot be detected when all input signals are normal, replace the PCM.
