GENERAL SCAN TOOL (GST) MODE 01 REFERENCE TABLE

M1131156000425

The purpose of this service of to allow access to cur-
rent emission-related data values, including ana-
logue inputs and outputs, digital inputs and outputs, 
and system status information.
The request for information includes a parameter 
identification (PID) value that indicates to 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.
