3B-16 Differential:
4WD Position Indicator Remains ON Steady at Ignition Switch ON
S6RW0C3204013
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.
Troubleshooting
3
CAN 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
1) Turn ignition switch to OFF position.
2) Check for fuse blown to “METER” fuse in junction block
assembly.
Is “METER” fuse in good condition?
Go to Step 5.
Replace “METER” fuse
and check for short.
5
Combination 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.
6
Combination 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.
