4WD Position Indicator Remains ON Steady at Ignition Switch ONS6RW0D3204014
Wiring Diagram
Refer to “4WD Position Indicator Does Not Come ON at Ignition Switch ON but Engine Stops”.
Circuit Description
Transfer position indicator operates according to the signal from 4WD control module. If the 4WD control system is in
good condition, 4WD position indicator light up for 2 seconds when ignition switch is turned to ON position, and then
turned to OFF position. If an abnormality is detected in the system, 4WD position indicator remains lighting.
Troubleshooting3CAN communication circuit check
1) Check CAN communication circuit between combination
meter and 4WD control module referring to “DTC U0073:
Control Module Communication Bus Off”.
Is CAN communication circuit in good condition?Go to Step 4. Repair or replace.
4“METER” fuse check

and check for short.
5Combination meter power supply check
1) Remove combination meter referring to “Combination
Meter Removal and Installation in Section 9C”.
2) Check proper connection to “WHT/RED” and “BLK” wire
terminal of combination meter connector.
3) If OK, then turn ignition switch to ON position and
measure voltage between “WHT/RED” wire terminal of
combination meter connector and vehicle body ground.
Is it 10 – 14 V?Go to Step 6. “WHT/RED” wire is
open circuit.
6Combination meter ground circuit check
1) Turn ignition switch to OFF position.
2) Measure resistance between “BLK” wire terminal of
combination meter connector and vehicle body ground.
Is resistance 1
Ω or less?Substitute a known-
good combination meter
and recheck. If 4WD
position indicator still
remains OFF, substitute
a known-good 4WD
control module and
recheck.“BLK” wire is open or
high resistance circuit. Step Action Yes No
Step Action Yes No
1Check DTC
1) Check DTC referring to “DTC Check”.
Is there any DTC(s)?Perform DTC flow to
repair and retry.Go to Step 2.
2CAN communication circuit check
1) Check CAN communication circuit between combination
meter and 4WD control module referring to “DTC U0073:
Control Module Communication Bus Off”.
Is CAN communication circuit in good condition?Substitute a known-
good combination meter
and recheck. If 4WD
position indicator still
remains off, substitute a

Problem symptom confirmation
Check if what the customer claimed in “Customer
Questionnaire” is actually found in the vehicle and if that
symptom is found, whether it is identified as a failure.
(This step should be shared with the customer if
possible.) Check warning lights related to brake system
referring to “EBD Warning Light (Brake Warning Light)
Check” and “ABS Warning Light Check”.
DTC check, record and clearance
Perform “DTC Check” procedure, record it and then
clear it referring to “DTC Clearance”.
Recheck DTC referring to “DTC Check”.
When DTC which is recorded at DTC check procedure is
detected again after performing DTC clearance, go to
“Step 4: ABS Check: ” to proceed the diagnosis.
When DTC which is recorded at DTC check procedure is
not indicated anymore after performing DTC clearance,
ABS control module does not perform the system
diagnosis, or temporary abnormality may occur,
therefore go to “Step 2: Driving Test: ” to proceed the
diagnosis.
Step 2: Driving Test
Test drive the vehicle at 40 km/h (25 MPH) for more than
a minute and check if any trouble symptom (such as
abnormal lighting of ABS warning light) exists.
If the malfunction DTC is confirmed again at ignition
switch ON, driving test as described is not necessary.
Proceed to Step 3.
Step 3: DTC Check
Recheck DTC referring to “DTC Check”.
Step 4: ABS Check
According to ABS Check for the DTC confirmation in
Step 3, locate the cause of the trouble, namely in a
sensor, switch, wire harness, connector, actuator
assembly or other part and repair or replace faulty parts.
Step 5: Brakes Diagnosis
Check the parts or system suspected as a possible
cause referring to “Brakes Symptom Diagnosis in
Section 4A” and based on symptoms appearing on the
vehicle (symptom obtained through Steps 1 and 2 and
repair or replace faulty parts, if any).
Step 6: Check for Intermittent Problem
Check parts where an intermittent trouble is easy to
occur (e.g., wire harness, connector, etc.), referring to
“Intermittent and Poor Connection Inspection in Section
00” and related circuit of trouble code recorded in Step 1
to 3.
Step 7: Final Confirmation Test
Confirm that the problem symptom has gone and the
ABS is free from any abnormal conditions. If what has
been repaired is related to the malfunction DTC, clear
the DTC once referring to “DTC Clearance” and perform
test driving and confirm that no DTC is indicated.ABS Warning Light CheckS6RW0D4504002
1) Turn ignition switch ON.
2) Check that ABS warning light (1) comes ON for
about 2 seconds and then goes off.
If any faulty condition is found, advance to “ABS
Warning Light Does Not Come ON at Ignition Switch
ON” or “ABS Warning Light Comes ON Steady”.
EBD Warning Light (Brake Warning Light)
Check
S6RW0D4504003
NOTE
Perform this check on a level place.

1) Turn ignition switch ON with parking brake applied.
2) Check that EBD warning light (brake warning light)
(1) is turned ON.
3) Release parking brake with ignition switch ON and
check that EBD warning light (brake warning light)
goes off.
If it doesn’t go off, go to “EBD Warning Light (Brake
Warning Light) Comes ON Steady”.

Refer to the same item in “Malfunction Indicator Lamp (MIL) Check in Section 1A” for checking procedure.
Transmission Warning Light Check (Non-Euro-OBD model)S6RW0D5104053
1) Turn ignition switch ON.
2) Check that transmission warning light lights for about 2 – 4 sec. and then goes OFF.
If anything faulty is found, advance “Transmission Warning Light Circuit Check – Light Does Not Come “ON” at
Ignition Switch ON (Non-Euro-OBD Model)” or “Transmission Warning Light Circuit Check – Light Remains “ON”
at Ignition Switch ON (Non-Euro-OBD Model)”.
DTC TableS6RW0D5104004
NOTE
• There are two types of OBD system depending on the vehicle specification.For identification, refer
to “Precaution on On-Board Diagnostic (OBD) System in Section 1A”.
• For non-Euro-OBD model, some of DTC No. with (*) mark in the following table can not be detected
by TCM depending on vehicle specification and local regulation.
• With the CAN communication OBD generic scan tool, DTC No. with delta (U) mark in the following
table can not be read.
• A: Driving cycles when MIL lighting and storing DTC in TCM memory for Euro OBD model.
• B: Driving cycles when transmission warning light lighting and storing DTC in TCM memory for non-
Euro-OBD model.
• 1 driving cycle: MIL or transmission warning light lights up when DTC is detected during 1 driving
cycle.
• 2 driving cycles: MIL or transmission warning light lights up when the same DTC is detected also in
the next driving cycle after DTC is detected and stored temporarily in the first driving cycle.
• Driving cycle with (*): MIL or transmission warning light does not light up but TCM detects and
stores DTC.

Also check the following items at engine start, if possible.
• Malfunction indicator lamp ----- Operation “Malfunction Indicator Lamp (MIL) Check”
• Transmission warning light ----- Operation “Transmission Warning Light Check (Non-Euro-
OBD model)”
• Charge warning lamp ----- Operation “Generator Symptom Diagnosis in Section 1J”
• Engine oil pressure warning lamp ----- Operation “Oil Pressure Warning Light Symptom Diagnosis in
Section 9C”
• Engine coolant temp. meter ----- Operation “Engine Coolant Temperature (ECT) Meter
Symptom Diagnosis in Section 9C”
• Other parts that can be checked visuallyInspection item Referring
