3. FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
If large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to yo\
ur customer.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
(c) Avoid spark jump test. (1) Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine.
(d) Avoid prolonged engine compression measurement. Engine compression tests must be done as rapidly as possible.
(e) Do not run engine when fuel tank is nearly empty. This may cause the engine to misfire and create an extra load on the con\
verter.
(f) Avoid coasting with ignition turned off.
(g) Do not dispose of used catalyst along with parts contaminated with gasol\
ine or oil.
4. IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM
For vehicles with mobile communication systems such as two− way radios and cellular telephones, observe
the following precautions. (1) Install the antenna as far as possible away from the ECU and sensors of the vehicle’\
s electronic
system.
(2) Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and se\
nsors of the ve- hicle’s electronic systems. For details about ECU and sensors locations, refer\
to the section on
the applicable component.
(3) Avoid winding the antenna feeder together with other wiring as much as possible, and also avoid
running the antenna feeder parallel with other wire harnesses.
(4) Check that the antenna and feeder are correctly adjusted.
(5) Do not install powerful mobile communications system.
5. FOR USING OBD II SCAN TOOL OR TOYOTA HAND −HELD TESTER
CAUTION:
Observe the following items for safety reasons:
Before using the OBD II scan tool or TOYOTA hand −held tester, the OBD II scan tool’s instruc-
tion book or TOYOTA hand −held tester’s operator manual should be read thoroughly.
Be sure to route all cables securely when driving with the OBD II scan too\
l or TOYOTA hand −
held tester connected to the vehicle. (i.e. Keep cables away from feet,\
pedals, steering wheel
and shift lever.)
Two persons are required when test driving with the OBD II scan tool or TOYOTA hand −held
tester, one person to drive the vehicle and the other person to operate the OBD\
II scan tool or
TOYOTA hand−held tester.

DIAGNOSTICS ENGINE
1996 LAND CRUISER (RM451U)
The diagnosis system operates in normal mode
during normal vehicle use. It also has a check mode
for technicians to simulate malfunction symptoms
and troubleshoot. Most DTC use 2 trip detection
logic* to prevent erroneous detection, and ensure
thorough malfunction detection. By switching the
ECM to check mode when troubleshooting, the
technician can cause the MIL to light up for a mal-
function that is only detected once or momentarily
(TOYOTA hand−held tester only) (See step 2).
*2 trip detection logic:
When a logic malfunction is first detected, the mal-
function is temporarily stored in the ECM memory.
If the same malfunction is detected again during the
second drive test, this second detection causes the
MIL to light up.
The 2 trip repeats the same mode a 2nd time (How-
ever, the IG switch must be turned OFF between the
1st trip and 2nd trip.).
Freeze frame data:
Freeze frame data records the engine condition
when a misfire (DTC P0300 − P0306) or fuel trim
malfunction (DTC P0171, P0172) or other malfunc-
tion (first malfunction only), is detected.
Because freeze frame data records the engine
conditions (fuel system, calculator load, engine
coolant temperature, fuel trim, engine speed, ve-
hicle speed, etc.) when the malfunction is detected,
when troubleshooting it is useful for determining
whether the vehicle was running or stopped, the en-
gine warmed up or not, the air− fuel ratio lean or rich,
etc. at the time of the malfunction.
Priorities for troubleshooting:
If troubleshooting priorities for multiple DTCs are given in the
applicable diagnostic chart, these should be followed.
If no instructions are given troubleshoot DTCs according to the
following priorities. (1) DTC other than fuel trim malfunction (DTC P0171,
P0172), EGR (DTC P0401, P0402), and misfire
(DTC P0300 − P0306).
(2) Fuel trim malfunction (DTC P0171, P0172), and EGR (DTC P0401, P0402).
(3) Misfire (DTC P0300 − P0306).
(b) Check the DLC3. The vehicle’s ECM uses V.P.W. (V ariable Pulse Width) for
communication to comply with SAE J1850. The terminal
arrangement of DLC3 complies with SAE J1962 and
matches the V.P.W. format.

DIAGNOSTICS AUTOMATIC TRANSMISSION
DI−141
1996 LAND CRUISER (RM451U)
8. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation ATF temperature 50 − 80°C (122 − 176° F).
The line pressure test should always be carried out in pairs. One techni\
cian should observe
the conditions of wheels or wheel stoppers outside the vehicle while the ot\
her is doing the test.
Be careful to prevent SST’s hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transmission case right side and connect SST\
(See page AT−18
for the location to connect SST).
SST 09992 −00094 (09992 −00150, 09992−00270)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressed firmly on the brake pedal and shift into D p\
osition.
(6) Measure the line pressure when the engine is idling.
(7) Press the accelerator pedal all the way down. Quickly read the highest line pr\
essure when engine
speed reaches stall speed.
NOTICE:
Release the accelerator pedal and stop test if the rear wheels begin to rotate before the engine speed
reaches the specified stall speed.
(8) In the same manner, do the test in R position.
Specified line pressure:
Condition D position kPa (kgf/cm2, psi) R position kPa (kgf/cm2, psi)
