TRANSFER CONTROL SYSTEM 7D1-63
To neutral: After the correction step 5-2(*), neutral indicator blinks at 4Hz.
Check the function between H and L according to the chart for 4L to 4H instead of check
for the requirements of neutral.
Step Action Yes No
1 Is the ignition switch ON? Turn it OFF once. Go to step 2.
2 Turn ON the ignition switch and
check the valve. Do not start the
engine.
Has the valve check for 2
seconds been completed
normally? Go to step 3.
Refer to the paragraph about the
indicator when it does not react
when shifted from 2H to 4H (7D1-
37).
After taking the remedy, trace this
chart from the beginning.
3 Can be shifted to 2H and then to 4L? Go to step 4.
(Impossible usually.)
Failed controller Refer to the paragraph about
shifting from 2H to 4H.
In particular, check if not at the
Check4W D condition, return to
this chart and trace it from the
beginning.
In case of Check4W D, shifting to
2H is possible.
Returning to 4H is impossible.
Refer to the paragraph about
Check4W D.
4 Set to N position in case of AT and set to the neutral position in
case of MT and check if the lamp
blinks at 4Hz after operation. Failed T/M position switch and
harness (failure of TM1 and TM2
harness and their related
switches shown in the figure).
Incorrect wiring.
Repair as required and trace this
chart from the beginning. Shift back to 4H and go to step 5.
5 Start the engine and use the
vehicle.
Does the speedometer run at this
time? Go to step 6.
Failure of speed sensor or
disconnection or short of harness
(for the meter).
After repairing, trace this chart
from the beginning.
6 Check the harness between the transfer controller and speed
sensor.
(Check the engine rotation
detection harness at the same
time.)
Is any trouble noticed? Failed harness between the
transfer controller and speed
sensor.
After repairing, trace this chart
from the beginning.
(Repair the engine rotation
detection unit, if required.) Go to step 7.
7 Run the vehicle for several
meters, stop it, meet the
permission requirements for
operation limits.
Did you wait for several seconds
after the requirements were met? Failed controller.
Replace the controller and trace
this chart from the beginning. You did not wait for enough time.
Optimum waiting time is 1 second
or maximum 3 minutes,
depending on the previous
conditions.
Refer to the paragraph about
operation without failure.
*Before determining a trouble (Non-trouble mode)
For shifting to neutral, 2H and 4L switches should be pressed at the same time for 10 seconds.
For shifting from neutral to other position, 2H, 4H or 4L switch should be pressed for 10 seconds.
W hen shifting from neutral to other position, the lamp blinking at 2Hz indicates active condition.
W hen the lamp keeps blinking at 2Hz, follow the step for the case when the lamp keeps blinking at 2Hz when
shifting between positions.

Caution:
Never push or tow the vehicle in an attempt to start it.
Extensive damage to the emission system and other
vehicle parts will result.
(Only catalytic converter vehicle)
Treat both the discharged battery and the booster battery
with great care when using jumper cables.
Carefully follow the procedure outlined below.
Always be aware of the dangers of sparking.
Failure to follow the following procedure can result in:
a. Serious personal injury, specially to your eyes.
b. Extensive property damage from a battery explosion, battery acid discharge, or electrical file.
c. Extensive damage to the electronic components o
f
both vehicles.
Do not use a 24 volt booster battery.
Serious damage to the vehicle's electrical system and
electronic components will result.

Jump Starting Procedure
1. Set the parking brake on both vehicles.
2. If one or both vehicles is equipped with a manual transmission, place the gear shift in the "NEUTRAL"
position.
3. Turn off the ignition on both vehicles.
4. Turn off all vehicle lights and accessories.
5 Be sure that the two vehicles are not touching.

Attach the end of one jumper cable to the booster battery
positive terminal.
6
Attach the other end of the same cable to the discharged
battery positive terminal.
7. Once again, check that the booster battery has a 12 volt rating.
8.
Attach one end of the remaining booster cable to the
booster battery negative terminal.
9.
Attach the other end of the booster cable to a solid ground
(such as the air conditioner compressor mounting bracket
or the alternator mounting bracket) in the engine room o
f
the vehicle with the discharged battery.
10.Be sure that the ground connection is at least 500 mm (20 in) from the discharged battery.

Tachometer Off-Vehicle Inspection
Remove the tachometer from the meter assembly and
measure the resistance value and the current consumption
between each terminal.


SELF DIAGNOSTIC FUNCTION
Check that the speedometer, tachometer, fuel gauge, and
temperature gauge operate properly.

821R300033


Entering the self-diagnostic mode
1. Push in and hold the “Change Indicator and Reset” knob.
2. Turn the ignition ON.
3. W hen the LCD odometer turns ON, release the “Change Indicator and Reset” knob.
4. Push in and release the “Change Indicator and Reset” knob three times in quick succession.
The meter cluster is now in “Self-diagnostic” mode.
NOTE: Steps 2-4 must be performed within 7 seconds.
The meter cluster will not enter “Self-diagnostic” mode if any of
the following conditions occur:
1. The “Change Indicator and Reset” knob is not depressed when the ignition is turned ON.
2. The “Change Indicator and Reset” knob is released within 600ms of turning the ignition ON.
3. The “Change Indicator and Reset” knob is not depressed and released three times within 7 seconds.

Self –diagnostic mode
LCD condition
• All LCDs are lit during the transition from self-diagnostic
decision mode to self-diagnostic mode
• The odometer/trip indicator scrolls throng its entire range
approximately once every 600 ms. All digits are lit (segment
check indication). This continues until the self-diagnostic
mode is terminated.

Meter and gauge indications
Meter and gauge indications with the change indicator and
reset knob on (self-diagnostic mode) are as shown in the
following table.




RTW 78ASF000101


Speedometer 100 kilometers per hour
Tachometer 3,000 rpm
Fuel gauge
Temperature gauge Mid-point on the dial

All indications return to zero when the change indicator and
reset knob is turned off.
The self-diagnostic mode and the self-diagnostic decision
mode are cancelled when the ignition switch is turned to the
OFF position. They also cancel when a speed pulse is sensed.
If either of the self-diagnostic modes are cancelled by turning
the ignition switch to the OFF position, the diagnostic unit
remains in the stand-by condition.
If cancellation occurs when a speed pulse is sensed, the unit
remains in the ordinary operating condition.

INSPECTION OF REAR DEFOGGER HEAT
WIRE
• Heat wires are printed on the inner side of glass.
To clean, use a soft cloth and wipe horizontally along the wires.
• Never use glass cleaner or equivalent.
• W hen measuring voltage, wind a piece of tin foil around the
tip of the negative probe and press the foil against the wire
with your finger as shown.



(1) Turn the ignition switch on.
(2) Turn the defogger switch on.
(3) Measure the voltage between the three points on the heat wire and the (-) terminal with a voltmeter.
(4) Check that the voltage becomes smaller from
A to B to C.



(5) If there is a place where the voltage suddenly changes to
0V, there is a broken wire between there and the powe
r
side.
(6) Move the tester probe from the position where the voltage changes to 0V toward the power side and find where the
voltage suddenly increases.
