OSC - Drive Mode
The DRIVE MODE allows control of 2 transmission functions. Each OSC function has a unique set of vehicle operating requirements that the technician is required to meet before being allowed to operate OSC. The recommended procedure, when using the DRIVE MODE, is to command one parameter at a time. The DRIVE MODE allows the technician to control the following OSC functions on the transmission:
- OSCGEAR - Directs the PCM to upshift or downshift
- OSCTCC - Directs the PCM to lock or unlock the torque converter clutch
