P1815
P1815 MANUAL MODE SWITCHDESCRIPTION
Manual mode switch is installed in A/T device. It transmits manual mode switch, shift up and shift down switch signals to unified meter and A/C amp. Then unified meter and A/C amp. transmits signals to TCM with CAN communication.
Paddle shifter transmits shift up and shift down switch signals to unified meter and A/C amp. Then unified meter and A/C amp. transmits signals to TCM with CAN communication. (With paddle shifter)
TCM transmits the switch signals to unified meter and A/C amp. by CAN communication line. Then manual mode switch position is indicated on the A/T indicator. For inspection, refer to TM-165. Shift Position Indicator Circuit
