Using Output State Control and Accessing PIDs
To confirm that the OSC value was sent by the scan tool and the EEC 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.
The following is a list of OSC parameters and their corresponding PID:
OSC PARAMETER CHART
OSC Parameter PID
SSA SSA SS1F
SSB SSB SS2F
TCC TCC TCCF, TCCMACT (do not use PID TCCMCMD during OSC)
EPC EPC —
GR_CM GEAR TRANRAT
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 remains the
same as the value sent from OSC, then the OSC substitution was successful.
