Coding Method
1. Check and record engine type, axle ratio and tire size.
2. Ignition “OFF”.
3. Connect SCANNER with diagnosis connector in engine
room.
4. Ignition “ON”.
5. Read the current memorized specification in TOD control
unit.
6. Compare memorized specification with the checked record.
If not matched, perform a coding.
7. Read again memorized coding specification in TOD control
unit for confirmation of coding.
8. Check coding specification whether it matches with vehicle
or not. If not, perform a coding again.

5D2-20 TRANSFER CASE (TOD)
ELIMINATE THE MEMORIZED FAULT
CODE
When diagnose by SCANNER, it is required that you make
adequate service on defects against all fault codes. And then
you should delete the memorized fault codes in TOD control
unit using SCANNER as follows;
1. Connect SCANNER with diagnosis connector.
2. Select “trouble code clear” in SCANNER.
3. In “trouble code clear” screen, press “enter” key to erase
the fault code.
4. Confirm deletion of fault code and, if not, repeat 2.-3.
process.

Check connection status in TOD control unit connector.
1. Check connection status.
- Is it connected exactly?
2. In case of mal-connection, connect tightly then perform
the follows.
a. Delete fault code using Scan-100.
b. Ignition “OFF”.
c. Ignition “ON”.
d. Diagnose by Scan-100.
- Does it display fault code “1714”?
Yes
No
Yes
No
Check short of 10A fuse (fuse No.20).
1. Detach No.20 fuse from engine room fuse box.
2. Check the existence of short.
- Is fuse normal?
Yes
No
Check ground of TOD control unit.
1. Ignition “ON”.
2. Check voltage between 4/19 (+) pin and 17/18 (-)
using multi-tester (keep connection status).
- Specified value (battery is good)
- Measured value
3. Check short between 17/18 pin and body after
disconnect 30 pin connector.

5D2-22 TRANSFER CASE (TOD)
Check function of TOD control unit.
1. Even A1, A2, A3 and A4 test, if you could not find defect,
it is required to replace TOD control unit on basis of
below phenomena.
a. ”4WD CHECK” lamp illuminates continuously when
ignition “ON”.
b. Shift is not possible even 4H/4L switch operation.
c. Upon diagnosis by Scan-100, it displays on
“impossible communication with TOD control unit”
or fault code “1714, 1715, 1716”.
- Do occur the above defects?
Yes
No
