Using Output State Control (OSC) and Accessing PIDs
WARNING: This page is about a different car, the 2005 Mercury Sable and 2005 Ford Taurus. 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 diagnostic 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:
OUTPUT STATE CONTROL (OSC) AND ACCESSING PIDS
| OSC Parameter | Corresponding PID | Additional PIDs |
|---|---|---|
| SS1 | SS1 | SS1F |
| SS2 | SS2 | SS2F |
| SS3 | SS3 | SS3F |
| LINEPDSD | LINEPDSD | EPC |
| TCC | OSCTCC | TCC, TCCF, TCCMD, TCCACT |
| GEAR | OSCGEAR | GEAR, TP, RPM, TSS, OSS, TR, TFT, TRANRAT, VS |
