If repairs are needed always use wire that is of the same or larger gauge.
MEASURING VOLTAGE DROP — ACCUMULATED METHOD

Connect the DMM across the connector or part of the circuit you want to check. The positive lead of the
DMM should be closer to power and the negative lead closer to ground.

Operate the circuit.

The DMM will indicate how many volts are being used to “push” current through that part of the circuit.
Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.
MEASURING VOLTAGE DROP — STEP-BY-STEP
The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those in
“Computer Controlled Systems”).
Circuits in the “Computer Controlled System” operate on very low amperage.
The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the
system. Such resistance variation may be caused by poor connection, improper installation, improper wire
gauge or corrosion.
The step by step voltage drop test can identify a component or wire with too much resistance.

Control Unit Circuit Test
System Description:When the switch is ON, the control unit lights up the lamp.
INPUT-OUTPUT VOLTAGE CHART
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. Control unit
does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to light up the
lamp.
INPUT-OUTPUT VOLTAGE CHART
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0V. Control unit does
not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not control ground to light up the lamp.

Control Units and Electrical PartsNAS0009Q
PRECAUTIONS

Never reverse polarity of battery terminals.

Install only parts specified for a vehicle.

Before replacing the control unit, check the input and output and functions of the component parts.

Do not apply excessive force when disconnecting a connector.

Do not apply excessive shock to the control unit by dropping or
hitting it.

Be careful to prevent condensation in the control unit due to
rapid temperature changes and do not let water or rain get on it.
If water is found in the control unit, dry it fully and then install it in
the vehicle.

Be careful not to let oil to get on the control unit connector.

Avoid cleaning the control unit with volatile oil.

Do not disassemble the control unit, and do not remove the
upper and lower covers.

When using a DMM, be careful not to let test probes get close to
each other to prevent the power transistor in the control unit
from damaging battery voltage because of short circuiting.

When checking input and output signals of the control unit, use
the specified check adapter.

LIFTING POINTPFP:00000
Commercial Service Tools NAS0000U
CAUTION:

Every time the vehicle is lifted up, maintain the complete vehicle curb condition.

Since the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up point on the rear side garage jack with a mission
jack or equivalent.

Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the front side garage jack with a mission jack or
equivalent.

Be careful not to smash or do not do anything that would affect piping parts.
Garage Jack and Safety Stand NAS0000V
WARNING:

Park the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes,
tubes, etc. under the vehicle.

Never get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.

Place wheel chocks at both front and back of the wheels on the ground.

Vehicle Recovery (Freeing a Stuck Vehicle) NAS0000Z
FRONT
After removing the front licence plate (if so equipped),
1 Remove the recovery hook cover from the bumper.
2 Securely install the recovery hook stored with jacking tools.
Make sure that the hook is properly secured in the stored place after
use.
WARNING:

Stand clear of a stuck vehicle.

Do not spin your tires at high speed. This could cause them
to explode and result in serious injury. Parts of your vehicle
could also overheat and be damaged.
CAUTION:

Tow chains or cables must be attached only to the vehicle recovery hooks or main structural mem-
bers of the vehicle. Otherwise, the vehicle body will be damaged.

Do not use the vehicle tie downs to free a vehicle stuck in sand, snow, mud, etc. Never tow a vehi-
cle using the vehicle tie downs or recovery hooks.

Always pull the cable straight out from the front of the vehicle. Never pull on the vehicle at an
angle.

Pulling devices should be routed so they do not touch any part of the suspension, steering, brake
or cooling systems.

Pull devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
If your vehicle is stuck in sand, snow, mad, etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control System (if so equipped).
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around front tires.
4. Slowly rock the vehicle forward and backward.

Shift back and forth between R (reverse) and D (drive) (automatic transmission models) or 1st (low)
and R (reverse) (manual transmission models).

Apply the accelerator as little as possible to maintain the rocking motion.

Release the accelerator pedal before shifting between R and D (automatic transmission models) or 1st
and R (manual transmission models).

Do not spin the tires above 35 MPH (55 km/h).
5. If the vehicle cannot be freed after a few tires, contact a professional towing service to remove the vehicle.

Towing hook is not available.
