5D2-32 TRANSFER CASE (TOD)
lPhenomenon
“4L” lamp on cluster continuous blinking and can not go off,
when operated 4H/4L switch as 4L« 4H.
lCause
Shifting failure.
1. Stop the vehicle
2. Return the 4H/4L switch to first position (before
operating).
- The blinking of 4L indicator lamp is stopped.
Note
If 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
