Using Output State Control (OSC) and Accessing PIDs
WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
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.
The following is a list of OSC parameters and their corresponding PID:
| OSC Parameter | Corresponding PID | Additional PIDs |
|---|---|---|
| SSA | SSA | SSAF |
| SSB | SSB | SSBF |
| SSC | SSC | SSCF |
| SSD | CCSF | - |
| 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.
