DCA

C1A15 GEAR POSITION





Description
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.

Is any DTC detected?
YES - Perform diagnosis on the detected DTC and repair or replace the malfunctioning parts. Testing and Inspection.
NO - GO TO 2.
2.CHECK VEHICLE SPEED SIGNAL
Check that "VHCL SPEED SE" operates normally in "DATA MONITOR" of "ICC/ADAS".

CAUTION:
Be careful of the vehicle speed.
Is the inspection result normal?
YES - GO TO 3.

Check that "GEAR" operates normally in "DATA MONITOR" of "ICC/ADAS".

CAUTION:
Be careful of the vehicle speed.
Is the inspection result normal?
YES - GO TO 5.
NO - GO TO 4.
4.CHECK GEAR POSITION SIGNAL
Check that "GEAR" operates normally in "DATA MONITOR" of "TRANSMISSION".
Is the inspection result normal?
YES - GO TO 5.
NO - GO TO 6.
5.CHECK INPUT SPEED SENSOR SIGNAL
Check that "INPUT SPEED" operates normally in "DATA MONITOR" of "TRANSMISSION".
Is the inspection result normal?
YES - Replace the ADAS control unit. Service and Repair.
NO - GO TO 6.
6.CHECK TCM SELF-DIAGNOSIS RESULTS
