SS1, SS2, SS3 and TCC in Bench Mode

These OSC functions are used to command SS1, SS2, SS3 and TCC solenoids OFF and ON when carrying out an electrical circuit check.

The OSC functions for parameters SS1, SS2, SS3 and TCC allows the technician to choose the following options:

• OFF - Directs the PCM to command the solenoid OFF.
• ON - Directs the PCM to command the solenoid ON.
• XXX - Cancels OSC command for that particular solenoid and returns to normal operation.

The vehicle requirements for SENDING an OSC value for SS1, SS2, SS3 or TCC are as follows:

• Key ON and engine OFF or key ON and engine ON at idle.
• Gear selector in PARK or NEUTRAL.

The vehicle requirements MUST BE MET when SENDING the OSC value for SS1, SS2, SS3 or TCC solenoids. If the vehicle requirements are NOT MET when SENDING the OSC value, an ERROR MESSAGE will appear. When the ERROR MESSAGE is received, OSC is aborted and must be restarted. After SENDING the OSC value, if the vehicle requirements are no longer met, the ERROR MESSAGE will NOT appear, but the PCM will cancel the OSC value and NO ERROR message will appear. The OSC value XXX may be sent anytime to cancel OSC.
