System Description - Manual Mode
- The TCM receives the manual mode signal, non-manual mode signal, manual mode shift up signal and manual mode shift down signal from unified meter and A/C amp. via CAN Communication line. The TCM shifts shift pattern control to the manual mode based on these signals, and then shifts the A/T by operating each Solenoid valve according to the shift operation of the driver.
- The TCM prohibits the manual mode while being in fail-safe mode due to an A/T malfunction, etc. Refer to FAIL-SAFE .
- The TCM transmits the manual mode shift refusal signal to the unified meter and A/C amp. if the TCM refuses the transmission from the driving status of vehicle when the selector lever shifts to UP or DOWN side. The unified meter and A/C amp. blinks shift indicator on the combination meter and sounds the buzzer to indicate the driver that the shifting is not performed when receiving this signal. However, the TCM does not transmit the manual mode shift refusal signal in the conditions as per the following.
- When the selector lever shifts to DOWN side while driving in 1GR.
- When the selector lever shifts to UP side while driving in 7GR.
