Both Speed Sensor Faulty

If both the front and rear speed sensors are faulty con
tinuously for 0.5 seconds the 4WD CHECK lamp is
illuminated. The TCCU then responds as follows:

1. If the system is in high range the TCCU sets the

EMC touch off level based on a vehicle speed of
0 and wheel slip control is suspended.

2. If the system is in low range, the EMC duty cycle

is set to maximum until the system is shifted out
of low range.

3. All electric shift activity is halted until the Ignition

is cycled. If a shift is in progress it will be
completed.

If both speed sensors recover continuously for 0.5 sec-
ond the TCCU will function normally. The 4WD CHECK
lamp is turned off but the fault code will remain in
memory.

Electro-Magnetic Clutch Test

The electromagnetic clutch (EMC) is tested for open
circuit or short circuit to ground. If a fault is detected
continuously for 0.8 second the 4WD CHECK lamp is
t u r n e d   o n  a n d   a l l   T O D T M   a c t i v i t y   i s   h a l t e d .
If the EMC recovers continuously for 0.8 second the
TCCU will function normally. The 4WD CHECK lamp is
turned off but the fault code will remain in memory.

DIAGNOSTIC TROUBLE CODES
(DTCS)

When a fault is detected a diagnostic trouble code
(DTC) is stored in the TCCU and illuminates the 4WD
CHECK indicator. This DTC will remain in memory until
the TCCU is instructed to erase DTCs by scan tool.

Notice: DTCs can not be erased by disconnecting of
power supply to the TCCU.

Diagnostic Trouble Codes Table

CLEARING DIAGNOSTIC
TROUBLE CODES

When diagnose by scan tool, it is required that you
make adequate service on defects against all fault
codes. And then you should delete the memorized fault
codes in transfer case control unit (TCCU) using scan
tool as follows;

1. Connect a scan tool with dada link connector

(DLC).

2. Select TROUBLE CODE CLEAR in scan tool.

3. In TROUBLE CODE CLEAR screen, press ENTER

key to erase the fault code.

4WD CHECK INDICATOR STAYS ON WITH IGNITION SWITCH ON

KAA5D040

Circuit Description

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

Diagnostic Aids

•

If the 4WD CHECK indicator illuminates steadily the
TCCU may detect some fault. TCCU should be
checked by scan tool to solve the problem.

•

The 4WD CHECK indicator also illuminates steadily
if the terminal B2 of TCCU connector is shorted to
ground. The shorted wire or terminals should be re-
paired.

Test Description

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

2. This step, along with step 4, checks the short to

ground condition of the wire or terminals

Value(s)

1. Turn the ignition switch to OFF.
2. Disconnect the 18-pin connector from transfer case

control unit (TCCU).

3. Turn the ignition switch to ON and check the 4WD

CHECK bulb operation.

Does the 4WD CHECK indicator come on steadily?
Repair any short to ground circuit between terminal
B2 of TCCU connector and terminal A4 of cluster.
Is the repair complete?
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.
Does the 4WD CHECK indicator come on steadily?
Replace the TCCU.
Is the repair complete?
