Code No.16 ABS-ECU power supply system (abnormal
voltage drop or rise)Probable cause
This code is output if the ABS-ECU power supply voltage drops below or rises above
the rated values.
Furthermore, turning the ignition switch to ACC will erase this code.DMalfunction of battery

Caution
If battery voltage drops or rises during inspection, this code will be output as well. If the voltage
returns to standard value, this code is no longer output.
Before carrying out the following inspection, check the battery level, and refill it if necessary.

REMEDY FOR A FLAT BATTERY
When booster cables are used to start the engine when the
battery is completely flat and then the vehicle is immediately
driven without waiting for the battery to recharge itself to
some extent, the engine may misfire, and driving might not
be possible. This happens because ABS consumes a great
amount of current for its self-check function. If this happens,
recharge the battery fully.
Caution
The vehicle posture will be unstable during braking, so
do not drive the vehicle with the ABS-ECU connector
disconnected or with the ABS not operating for any other
reason.

"BAOPERATION CHECK window>
1. Install the glass to the window regulator assembly.
Caution
(1) As fully open position which is programed in the
power window-ECU is released (initialized), the
window regulator assembly should not be
operated until it is installed to the glass.
(2) The clamping prevention function does not
operate the first time that the glass is fully closed.
2. Press the power window switch to fully-open the glass,
and then return the glass toward the fully-close position
about 30 mm each. In the fully-close position, keep on
pressing the power window switch for 0.5 second or more.
NOTE
This operation will program the power window-ECU.

WINDSHIELD WIPER MOTOR CHECK
Inspection of windshield wiper motor is conducted by removing
the harness connector with the motor attached to the vehicle.
DOperation inspection of windshield wiper motor
rotation in a low or high speed
Connect the battery to the windshield wiper motor to
inspect the operation of motor rotation in a low or high
speed.
DInspection of windshield wiper motor stop position
(1) Connect the battery to the windshield wiper motor
to rotate the motor in a low speed as shown in the
illustration (A) and disconnect the battery during
rotation to stop the motor.
(2) Connect between the terminals and the battery as
shown in the illustration (B) and confirm whether the
motor stops at the automatic stop position after
rotating in a low speed.
FRONT WASHER MOTOR CHECK
(1) The inspection of front washer motor is conducted with
the washer hose connected after removing the washer
tank assembly and pouring water in the washer tank.
(2) Check that the water is supplied with strong pressure
after energizing terminal number 2 with battery voltage
and earthing terminal number 1.

SRS -SRS Service Precautions52B-3
SRS SERVICE PRECAUTIONS
1. In order to avoid injury to yourself or others
from accidental deployment of the air bag and
accidental operation of the seat belt with
pre-tensioner during servicing, read and
carefully follow all the precautions and
procedures described in this manual.
2. Do not use any electrical test equipment on
or near SRS components, except those
specified on P.52B-6.
3. Never Attempt to Repair the Following
Components:
DSRS air bag control unit (SRS-ECU)
DClock spring
DDriver’s and front passenger’s air bag
modules
DSeat belt with pre-tensionerNOTE
If any of these components are diagnosed as
faulty, they should only be replaced, in
accordance with the INDIVIDUAL COM-
PONENTS SERVICE procedures in this
manual. (Refer to P.52B-49.)
4. After disconnecting the negative (–) battery cable,
wait 60 seconds at least before any service and
insulate the disconnected cable with tape. The SRS
retain enough voltage to deploy the air bags for a
short time even after the disconnection of the battery.
So, serious injury may result by accidental air bag
deployment if a work is done on the SRS just after
the disconnection of the battery.
5. Do not attempt to repair the wiring harness connectors
of the SRS. If the connector(s) are diagnosed as defective,
replace the wiring harness(es). If the harness(es) are
diagnosed as faulty, replace or repair the wiring
harness(es) according to the table that follows.
