DIAGNOSTICS ANTI−LOCK BRAKE SYSTEM
1996 LAND CRUISER (RM451U)
ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects trouble, it lights the ABS warning light while at the same time prohibiting ABS control. At
this time, the ECU records a DTC in memory. After removing the short pin of the DLC1, connect terminals
Tc and E
1 of the DLC1 to make the ABS warning light blink and output the DTC.

PRE−CHECK
1. SRS WARNING LIGHT CHECK
(a) Turn the ignition switch to ACC or ON and check that the
SRS warning light lights up.
(b) Check that the SRS warning light goes out after approx. 6 seconds.
HINT:
When the ignition switch is at ACC or ON and the SRS
warning light remains on or flashes, the airbag sensor as-
sembly has detected a malfunction code.
If, after approx. 6 seconds have elapsed, the SRS warn-
ing light sometimes lights up or the SRS warning light
lights up even when the ignition switch is OFF, a short in
the SRS warning light circuit can be considered likely.
Proceed to ”SRS warning light system malfunction” on
page DI−274 , DI−276 .
2. DTC CHECK (Using diagnosis check wire)
(a) Output the DTC. (1) Turn the ignition switch to ACC or ON position andwait approx. 20 seconds.
(2) Using SST, connect terminals Tc and E1 of the
DLC1.
SST 09843−18020
(b) Read the DTC. Read the 2− digit DTC as indicated by the number of times
the SRS warning light blinks. As an example, the blinking
patterns, normal, 11 and 31 are as shown on the illustra-
tion.
Normal code indication
The light will blink 2 times per second.
Malfunction code indication
The first blinking output indicates the first digit
of a 2−digit DTC. After a 1.5 second pause,
the second blinking output will indicate the
second digit.

SRS Warning Light System Malfunction (Always lit up, when igni-
tion switch is in LOCK position.)
CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter.
When the SRS is normal, the SRS warning light lights up for approx. 6 seconds after the \
ignition switch is
turned from LOCK position to ACC or ON position, and then turns off automatically.
If there is a malfunction in the SRS, the SRS warning light lights up to\
inform the driver of the abnormality.
When terminals Tc and E1 of the DLC1 are connected, the DTC is displayed by the blinking\
of the SRS warn-
ing light.

Periodic maintenance service must be performed according to whichever interval in\
the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time inter\
val (months).
Maintenance service after the last period should be performed at the same interval \
as before unless
otherwise noted.
Failure to do even one item can cause the engine to run poorly and incre\
ase exhaust emissions.
2. LIGHTS
(a) Check that the headlights, stop lights, taillights, turn signal lights, \
and other lights are all working.
(b) Check the headlights aim.
3. WARNING LIGHTS AND BUZZERS

(b) Check that the wipers do not streak.
7. WINDSHIELD DEFROSTER
Check that air comes out from the defroster outlet when operating the heater \
or air conditioner at defroster
mode.
8. REAR VIEW MIRROR
Check that it is mounted securely.
9. SUN VISORS
Check that they move freely and mounted securely.
10. STEELING WHEEL
Check that it has the specified freeplay. Be alert for changes in steering condition, such as hard steering,
excessive freeplay or strange noises.
11. SEATS
(a) Check that all front seat controls such as seat adjusters, seatback recl\
iner, etc. operate smoothly.
(b) Check that all latches lock securely in any position.
(c) Check that the head restraints move up and down smoothly and that the lo\
cks hold securely in any latch position.
(d) For folding −down rear seat backs, check that the latches look securely.
12. SEAT BELTS
