GENERAL SCAN TOOL (GST) MODE 01 REFERENCE TABLE
M1131156000492
The purpose of this service is to allow access to cur-
rent emission-related data values, including analog
inputs and outputs, digital inputs and outputs, and
system status information.
The request for information includes a parameter
identification (PID) value that indicates the on-board
system the specific information requested.
The ECM will respond to this message by transmit-
ting the requested data value last determined by the
system. All data values returned for sensor readings
will be actual readings, not default or substitute val-
ues used by the system because of a fault with that
sensor.
NOTE: GST MODE 01 can be accessed through the
use of a general scan tool.
