Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
