Solenoid Characterization
The line pressure solenoid control valve is tested after assembly to determine the output fluid pressure at certain electrical current values, applied to coil windings. This information is referred to as solenoid current/pressure data points. The solenoid valves are tested two ways, with an increasing and decreasing electrical current applied to the coil windings. The resultant current versus pressure data points are saved and assigned a file number. The file number is marked on the solenoid valve housing end. The performance data file is stored on the TIS web site. This data file is programmed and stored in the vehicle's hybrid/EV powertrain control module 1. Replacing any of the following components will require the hybrid/EV powertrain control module 1 to be programmed with the new or existing solenoid valve performance data.
- Hybrid/EV powertrain control module 1 - program the new hybrid/EV powertrain control module 1 with the existing solenoid data files stored on the TIS web site for the line pressure solenoid control valve.
- Line pressure solenoid control valve - program the hybrid/EV powertrain control module 1 with the new solenoid data file stored on the TIS web site for the line pressure solenoid control valve.
- Control valve body assembly - program the hybrid/EV powertrain control module 1 with the existing solenoid data files stored on the TIS web site for the line pressure solenoid control valve.
- Line pressure solenoid control valve and control valve body as a complete assembly - program the hybrid/EV powertrain control module 1 with the new solenoid data file stored on the TIS web site for the line pressure solenoid control valve.
- Transmission Assembly - A new transmission assembly will have the solenoid characterization data programmed into the hybrid/EV powertrain control module 1.
