OSC - Bench Mode

WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The Bench Mode is functional only when the gear selector is in PARK or NEUTRAL. The Bench Mode may be used when the engine is either ON (running) or OFF. The Bench Mode allows the technician to function the following components:

SSA/SS1 - Directs PCM to command Shift Solenoid A OFF or ON
SSB/SS2 - Directs PCM to command Shift Solenoid B OFF or ON
SSC/SS3 - Directs PCM to command the current to the 3-2 Timing/Coast Clutch Solenoid
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 0 to 300 PSI. The PCM will command the appropriate PCA current to obtain the commanded line pressure.
PCB - Directs PCM to command pressure control solenoid B from 0 to 500 PSI. The PCM will command the appropriate PCB solenoid current to obtain the commanded pressure.
