C1A15 GEAR POSITION
C1A15 GEAR POSITION
Description
INFOID:0000000006224328
ADAS control unit judges the gear position based on the following signals.
• Current gear position signal transmitted from TCM via CAN communication.
• Value of gear ratio calculated from input speed signal transmitted from TCM via CAN communication.
• Value of gear ratio calculated from the vehicle speed signal transmitted from ABS actuator and electric unit
(control unit) via CAN communication.
