LINEDSD and PCB in Bench Mode

The LINEDSD in Bench Mode may be used when carrying out an electrical check on the line pressure control (LPC) or PCB solenoids or used to test the functionality of the transmission's electronic control of the line pressure. When testing the LPC or PCB for controlling the line pressure the technician is required to run the engine greater then 1,500 RPM. The hookup of a hydraulic pressure gauge is required to actually test whether the transmission line pressure is correct. This will test whether the hydraulic pump, the pressure regulator and the LPC/PCB solenoid and other associated mechanical and hydraulic components are working correctly.

The OSC functions for the parameter LINEDSD and PCB allows the technician to choose pressure between 0 and 300 psi for LINEDSD and between 0 and 500 psi for PCB:

The vehicle requirements for sending an OSC value for LINEDSD and PCB in Bench Mode is as follows:

• Key on/engine running, engine speed greater then 1,500 RPM.
• Gear selector in PARK or NEUTRAL.

The vehicle requirements must be met when sending the OSC value for LINEDSD or PCB. If the vehicle requirements are not met when sending the OSC value, the command will be canceled. After the OSC value for LINEDSD or PCB is sent, if the vehicle requirements are no longer met, the command will be canceled.
