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.

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

l

Phenomenon

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

continuously.

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

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
