NOTE: The shift on the fly system is not changed
between 2WD and 4WD modes normally.
CAUTION: If code 32 or 33 is also observed, remove
the trouble associated with code 32 or 33 first.

(P1762)The ADC line is short-circuited to
GND.—
NOTE:
The on/off signal line of the shift on the fly system is
short–circuited to GND.
The system enters into the fail-safe mode because of
fusing or system protection.
(If a short–circuit is observed on GND, the output to
the on/off signal line becomes 0V.)
