DIAGNOSTICS CRUISE CONTROL SYSTEM
1996 LAND CRUISER (RM451U)
HINT:
If the DTC is not output, inspect the diagnosis circuit (See page
DI-333 )
As an example, the blinking patterns for codes; normal, 11 and
21 are shown in the illustration.
2. ECU TERMINAL VALUES MEASUREMENT BY USING TOYOTA BREAK-OUT-BOX AND TOYOTA HAND-
HELD TESTER
(a) Hook up the TOYOTA break- out- box and TOYOTA hand-held tester to the vehicle.
(b) Read the ECU input/output values by following the prompts on the tester screen.
(c) Please refer to the TOYOTA hand-held tester has a ºSnapshotº function. This records the measured data and
is effective in the diagnosis of intermittent problems.
3. DTC CLEARANCE
(a) After completing repairs, the diagnostic trouble code re- tained in memory can be cleared by removing the ECU-B
fuse for 10 seconds or more, with the ignition switch off.
(b) Check that the normal code is displayed after connecting the fuse.

(b) Push the main switch ON º2º.
(c) Check that the CRUISE MAIN indicator light blinks twice or 3 times repeatedly after 3 seconds.
(d) Turn the SET/COAST or RES/ACC switch OFF.
(e) Operate each switch as listed in the table below.
(f) Read the blinking pattern of the CRUISE MAIN indicator light.
(g) After performing the check, turn the main switch OFF.
