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.

DIAGNOSIS

Malfunction interior TOD control unit ; fault code
1714

Phenomenon

1. When ignition “ON”, “4WD CHECK” lamp illuminates

continuously.

2. On diagnosis by SCAN-100, it displays fault code “1714”.

Cause ; Error of EEPROM checksum in TOD control unit

Specified Value

/Yes/No

Countermeasure

Check power supply for TOD control unit.

1. Disconnect 30 pin connector from TOD control unit.
2. Ignition “ON”.
3. Using multi-tester, measure voltage between pin 5(+)

and 17/18 (-).
- Specified value
- Measured value is within specified range ?

11-14 Vdc

Yes

Perform A2 stage
Perform A3 stage

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

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

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.
- Is resistance "

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

Replace TOD control
unit
Normal system
