SSA/SS1, SSB/SS2, SSC/SS3 and TCC in Bench Mode
These OSC functions are used to command SSA/SS1, SSB/SS2, SSC/SS3 and TCC solenoids OFF and ON when carrying out an electrical circuit check.
The OSC functions for parameters SSA/SS1, SSB/SS2 and SSC/SS3 allows the technician to choose the following options:
- OFF - Directs PCM to command the solenoid OFF.
- ON - Directs PCM to command the solenoid ON.
The OSC options to control TCC for the torque converter clutch solenoid in Bench Mode are as follows:
- 0% - Commands PCM to control duty cycle to 0%.
- 100% - Commands PCM to control duty cycle to 100%.
Controlling the solenoids allows the technician to measure the circuit current using an inductive pickup or to measure the circuit voltage when carrying out electrical tests.
The vehicle requirements for SENDING an OSC value for SSA/SS1, SSB/SS2, SSC/SS3 and TCC are as follows:
- Key on/engine off or key on/engine running at idle.
- Gear selector in PARK or NEUTRAL.
The vehicle requirements must be met when sending the OSC value for SSA/SS1, SSB/SS2, SSC/SS3 and TCC commands. If the vehicle requirements are not met when sending the OSC value, the command is canceled. After sending the OSC value, if the vehicle requirements are no longer met, the OSC value will be canceled by the PCM (monitoring corresponding PID).
