DIAGNOSTICS AUTOMATIC TRANSMISSION
1996 LAND CRUISER (RM451U)
The diagnosis system operates in normal mode
during normal vehicle use, and also has a check
mode for technicians to simulate malfunction symp-
toms and perform troubleshooting. Most DTCs use
2 trip detection logic(*) to prevent erroneous detec-
tion. By switching the ECM to check mode when
troubleshooting, the technician can cause the MIL
to light up for a malfunction that is only detected
once or momentarily (TOYOTA hand−held tester)
(See step 3).
*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 2nd test
drive, this 2nd detection causes the MIL to light up.
2. Normal Mode: INSPECT DIAGNOSIS
(a) Check the MIL. (1) The MIL lights up when the ignition switch is turnedON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter
(See page BE−2 ).
(2) When the engine is started, the MIL should go off.
If the lamp remains on, the diagnosis system has
detected a malfunction or abnormality in the sys-
tem.
(b) Check the DTC.
NOTICE:
TOYOTA hand−held tester only:
When the diagnostic system is switched from the normal
mode to the check mode, it erases all DTCs and freeze
frame data recorded in the normal mode. So before switch-
ing modes, always check the DTCs and freeze frame data,
and note them down. (1) Prepare the OBD II scan tool (complying with SAEJ1978) or TOYOTA hand−held tester.
(2) Connect the OBD II scan tool or TOYOTA hand−
held tester to the DLC3 in the fuse box at the lower
left of the instrument panel.
(3) Turn the ignition switch ON and turn the OBD II scan
tool or TOYOTA hand−held tester switch ON.

(4) Use the OBD II scan tool or TOYOTA hand−held
tester to check the DTCs and freeze frame data.
Note them down (For operating instructions, see
the OBD II scan tool’s instruction book).
(5) See page DI−143 to confirm the details of the
DTCs.
NOTICE:
When simulating symptoms with an OBD II scan tool (ex-
cluding TOYOTA hand −held tester) to check the DTCs, use
the normal mode. For codes on the DTC chart subject to ”2
trip detection logic”, turn the ignition switch off after the
symptoms have been simulated for the 1st time. Them re-
peat the simulation process again. When the program has
been simulated twice, the MIL lights up and the DTCs are
recorded in the ECM.
3. Check Mode: INSPECT DIAGNOSIS
HINT:
TOYOTA hand−held tester only:
Compared to the normal mode, the check mode has high sens-
ing ability to detect malfunctions. Furthermore, the same diag-
nostic items which are detected in the normal mode can also be
detected in check mode.
(a) Check the DTC. (1) Check the initial conditions.
Battery positive voltage 11 V or more.
Throttle valve fully closed.
Transmission in P position.
Air conditioning switched off.
(2) Turn the ignition switch OFF.
(3) Prepare the TOYOTA hand−held tester.
(4) Connect the TOYOTA hand− held tester to the
DLC3 in the fuse box at the lower left of the instru-
ment panel.
(5) Turn the ignition switch ON and switch the T OYOTA
hand −held tester ON.
(6) Switch the TOYOTA hand −held tester from the nor-
mal mode to the check mode (Check that the MIL
flashes).
(7) Start the engine (The MIL goes).
(8) Simulate the conditions of the malfunction de- scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTCs etc.
