PID/DATA MONITOR TABLE [POWER LIFTGATE (PLG) SYSTEM]
PID/DATA MONITOR CHART
NOTE:
The PID data screen function is used for monitoring the calculated
value of input/output signals in the module. Therefore, if the
monitored value of the output parts is not within the specification, it
is necessary to inspect the monitored value of input parts
corresponding to the applicable output part control. In addition,
because the system does not display an output part malfunction as
an abnormality in the monitored value, it is necessary to inspect the
output parts individually.
