Diagnostic Parameters Identification (Pid) Chart

Diagnostic Parameters Identification (PID) Chart

Special Tool(s):

Using Output State Control (OSC) and Accessing PIDs
To confirm that the OSC value was sent by the scan tool and the PCM has accepted the OSC substitution, a corresponding PID for each OSC parameter must be monitored. Additional PIDs should be monitored to help the technician adequately diagnose the transmission.

To confirm that the OSC substitution occurred, SEND the OSC value and monitor the corresponding PID value. If no ERROR MESSAGE was received and the value of the corresponding PID is the same as the value sent from OSC, then the OSC substitution was successful.
