OSC - Bench Mode

The Bench Mode is functional only when the vehicle range selector is in PARK or NEUTRAL. The Bench Mode may be used when the engine is either ON (running) or OFF (not running). The Bench Mode allows the technician to function the following components:

• SSA - Directs PCM to command Shift Solenoid 1 OFF or ON
• SSB - Directs PCM to command Shift Solenoid 2 OFF or ON
• TCC - Directs PCM to command the Torque Converter Solenoid from 0% duty cycle to 100% duty cycle
• LINEDSD - Directs PCM to command line pressure from 234 kPa to 1.5 MPa (34 psi to 217 psi). The PCM will command the appropriate electronic pressure control (EPC) current to obtain the commanded line pressure.
