Kickdown function
| Kickdown function |
Trionic has a pedal sensor that provides information on the position of the accelerator pedal. When the angle of the pedal exceeds a determined value, Trionic will send bus information ”KICKDOWN ON”, unit ON/OFF. TCM uses this information to control the shifting points for maximum performance.
The Kickdown function is available in all shifting programs.
Diagnostics
In the event of a malfunction, a diagnostic trouble code will be generated primarily in the Trionic system.When bus communication with the Trionic system ceases, diagnostic trouble code P1921 will be generated and the transmission will go into Limp-Home mode.
Inaccurate information on the bus causes diagnostic trouble code P1971 to be generated. Depending on the fault, the TCM may activate the emergency operation program (Limp-Home mode).
