5D2-32 TRANSFER CASE - TOD

Circuit Description

When the ignition switch turns to ON the transfer case
control unit (TOD) illuminates 4WD CHECK and 4WD
LOW indicator to check bulb operation and turns off
after 0.6 seconds. Then TOD starts self-diagnosis and
illuminate 4WD CHECK indicator when TOD detects
any fault.

Diagnostic Aids

If the both of the 4WD CHECK and 4WD LOW indicator
were not illuminating there would be some problems
with fuse, power supply line, improper connection of
connector or transfer case control unit (TOD).

If one of the indicators illuminates, the fuse and power
supply line is good and the connector or TOD may be
the cause of problems.

NO 4WD CHECK OR 4WD LOW INDICATOR WITH IGNITION SWITCH ON

Test Description

The number(s) below refer to step(s) on the diagnostic
table.

1. This step checks for the normal bulb operation.

Value

Step

Action

Check the bulb operation when the ignition switch turns
to ON.

Does the only 4WD LOW indicator come on and goes
after 0.6 seconds?
1. Turn the ignition switch to OFF.

2. Disconnect 18-pin connector from the transfer case

control unit (TOD).

3. Using test lamp check the continuity between terminal

B2 of TOD and ground.

Does the test lamp come on?

1. Turn the ignition OFF.

2. Check the pin or terminals for damage or improper

connection.

3. Reconnect all the connectors.

4. Turn the ignition ON.
Do the two indicators come on go after 0.6 seconds?

Repair or replace of following components:

•

4WD CHECK indicator bulb.

•

Open circuit between terminal A12 of cluster and
terminal B2 of TOD connector.

Is the repair complete?
1. Check the fuse F2 and indicator bulbs.

2. Check the continuity for following terminals:

•

Fuse F2 to B2 (TOD)

•

A2 (Cluster) to B2 (TOD)

•

B15 (Cluster) to B9 (TOD)

Are there any problems?

Repair open circuit or replace damaged parts.

Is the repair complete?
Replace the TOD.

TRANSFER CASE - TOD 5D2-33

SSANGYONG Y200

Circuit Description

When the 4H/4L switch turned from 4H (4L) to 4L (4H)
electric shift starts and 4WD LOW indicator begin to
blink until the shifting is completed or canceled. If 4H
to 4L shifting is completed the 4WD LOW indicator
will illuminated and 4L to 4H shifting is completed it
will be turned off.

If shifting fails the 4WD LOW indicator will blink
steadily until the shifting is completed or canceled.

Diagnostic Aids

The 4WD LOW indicator shows that the transfer case
is operating in low range. And the indicator will blink
while shifting from low to high range or high to low
range. If the indicator blinks steadily it warns the
shifting command and real position of the shift motor
or position encoder are not matched.

4WD LOW INDICATOR BLINK STEADILY

Yes

Value

Step

Action

1. Stop the vehicle.

2. Turn the 4H/4L switch to original position.
Does the 4WD LOW indicator stop blinking?

1. Make sure the vehicle stopped completely.

2. Set the shift lever to N (neutral) and wait more than 2

seconds.

3. Turn the 4H/4L switch.

Does the 4WD LOW indicator blink and stop after
complete shifting?

•

4H —> 4L: 4WD LOW indicator illuminates.

•

4L —> 4H: 4WD LOW Indicator turns off.

1. Starts TOD Diagnostic System Check.
2. If there were no trouble code, replace TOD.

5D2-34 TRANSFER CASE - TOD

EEPROM Checksum Fault

Circuit Description

When the ignition is turned on the transfer case control
unit (TOD) receives battery voltage and ignition volt-
age and illuminates the 4WD CHECK and 4WD LOW
indicators for 0.6 seconds. Then it starts self diagnosis
to check itself.

Conditions for Setting the DTC

DTC 1714 is an indication of a potential internal transfer
case control unit (TOD) malfunction. It will set if any of
following conditions is detected.

•

The calculated checksum for internal memory does
not match the stored value.

•

T h e p e r m a n e n t m e m o r y s t o r a g e a r e a i s
malfunctioning.

DIAGNOSTIC TROUBLE CODE (DTC) 1714

Action Taken When the DTC Sets

The TOD will illuminates 4WD CHECK indicator and
DTC is stored in TOD.

Diagnostic Aids

•

Check for poor connections, fuse and power supply
wiring.

•

Check for ground condition.

Test Description

The number(s) below refer to step(s) on the diagnostic
table.

2. This step checks the battery supply voltage.

4. This step checks the ground condition.
