Using Output State Control (OSC) and Monitoring PIDs
To confirm that the OSC value was sent by the scan tool and the PCM has accepted the OSC command, a corresponding PID for each OSC parameter must be monitored. After SENDING the OSC value, the corresponding PID value should be the same as the OSC value that was sent. Additional PIDs are listed that may be monitored to help the technician accurately diagnose the transaxle.
The following is a list of OSC parameters and their corresponding PIDs:
| OSC Parameter | Corresponding PID | Additional PIDs |
|---|---|---|
| HRSH_SHFT | HRSH_SHFT | |
| LINEDSD | LINEDSD | PCA, PCA AMP, PCA_F |
| TCC_OSC | TCC_OSC | TCCRAT, TCCMCMD, TSLIP |
| GEAR_OSC | GEAR_OSC | SHFT_TYP, GEAR, TRANRAT |
| SSA_AMP | SSA_AMP | SSPCA, SSPCA_F |
| SSB_AMP | SSB_AMP | SSPCB, SSPCB_F |
| SSC_AMP | SSC_AMP | SSPCC, SSPCC_F |
| SSD_AMP | SSD_AMP | SSPCD, SSPCD_F |
| PCA AMP | PCA AMP | PCA_F |
| TCC AMP | TCC AMP | TCCPC, TCCPC_F |
| SSA/SS1 | SSA/SS1 | SSA/SS1_F |
