Phenomenon “4L ” lamp on cluster continuous blinking and can not go off,
when operated 4H/4L switch as 4L « 4H.
CauseShifting failure.
1. Stop the vehicle
2. Return the 4H/4L switch to first position (before
operating).
- The blinking of 4L indicator lamp is stopped.
NoteIf the first position before switch operating is ‘4L ’ ,
lamp goes on after stopping blink, otherwise it is ‘4H ’ lamp goes off.
3. Reoperate 4H/4L switch to 4H 4L on the below
condition. Positioned Auto T/M to neutral.
 At this time, keep the neutral position for 2 second.
 Stop the vehicle (The R.P.M of front & Rear propeller
shaft is below 80).
4. ‘4L ’ lamp blinks based on 0.3 second.
5. When the shifting is engaged, the blinking of ‘4L ’ lamp
is stopped.
-4H 4L : goes on ‘4L ’ lamp
-4L 4H : goes on ‘4L ’ lamp
6. When the ‘4L ’ indicator lamp continuous blinking,
repositioned to first position and diagnose the system and then fix it. Ye s
