Neutral Signal Input
Malfunction

(Only for D27DT M/T
model)

- The neutral signal of M/T is sent to

CAN cluster which is then sent to
ECU via CAN communication.

- The ECU cannot detect whether

signal is missing due to the
malfunction in neutral signal and
wiring or due to the line malfunction.

- Check the wiring related to neutral

switch.
