Pattern Select Switch Circuit (2nd Start Switch) & 2nd Start
Switch Indicator Light Circuit
CIRCUIT DESCRIPTION
When 2nd start mode is selected with the pattern select switch, the ECM cont\
rols the solenoid valves and
the transmission starts from 2nd gear.
In D position, the transmission automatically shifts up through 3rd to O\
/D as usual.
In 2nd position, the transmission is held in 2nd gear.
WIRING DIAGRAM
(*) Pattern Select Switch (2nd Start Switch)
When the 2nd start switch is pushed, the switch is contacted and the 2nd\
mode is selected.
To cancel the 2nd start, push the 2nd start switch once again. The 2nd sta\
rt is automatically cancelled out
when the ignition switch is turned OFF.

PRE−CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
When the ignition switch is turned ON, check that the ABS
warning light goes on for 3 seconds.
HINT:
If the indicator check result is not normal, proceed to trou-
bleshooting for the ABS warning light circuit (See page
DI−230 ).
When the transfer is in L position (center dif ferential lock),
the ABS does not operate and the ABS warning light
stays ON.
(b) Check the DTC. (1) Confirm that the center differential is free.
(2) Disconnect the short pin from the DLC1.
(3) Using SST, connect terminals Tc and E
1 of the
DLC1.
SST 09843−18020
(4) Turn the ignition switch ON.
(5) Read the DTC from the ABS warning light on the combination meter.
HINT:
If no code appears, inspect the diagnostic circuit or ABS
warning light circuit (See page DI−233 or DI−230 ).

As an example, the blinking patterns for normal code and
codes 11 and 21 are shown in the illustration.
(6) Code are explained in the code table on page
DI−196 .
(7) After completing the check, disconnect terminals Tc
and E
1, and turn off the display.
If 2 or more malfunctions are indicated at the same time the low-
est numbered DTC will be displayed 1st.
(c) Clear the DTC.
(1) Confirm that the center differential is free.
(2) Using SST, connect terminals Tc and E
1 of the
DLC1 and remove the short pin from the DLC1.
SST 09843−18020
(3) Turn the ignition switch ON.
(4) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 3 seconds.
(5) Check that the warning light shows the normal
code.
(6) Remove the SST from the terminals of the DLC1.
SST 09843−18020
(7) Connect the short pin to the DLC1.
HINT:
Cancellation can also be done by removing the ECU −B fuse,
but in this case, other memory systems will also be cancelled
out.

(d) Using TOYOTA break −out− box and TOYOTA hand− held
tester, measure the ECU terminal values.
(1) Hook up the T OYOTA hand−held tester and TOYO-
TA break−out−box to the vehicle.
(2) Read the ECU input/output values by following the prompts on the tester screen.
HINT:
TOYOTA hand −held tester has a ”Snapshot ” function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems.
Please refer to the TOYOTA hand−held tester/TOYOTA break
out−box operators manual for further details.
2. SPEED SENSOR SIGNAL AND DECELERATION SEN-
SOR CHECK
(a) Check the speed sensor signal. (1) Conform that the center differential is free.
(2) Turn the ignition switch OFF.
(3) Using SST, connect terminals Ts and E
1 of the
DLC1.
SST 09843−18020
(4) Start the engine.
(5) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI−230).
(6) Drive vehicle straight forward.
HINT:
Drive vehicle faster than 45 km/h (28 mph) for several seconds.
(7) Stop the vehicle.
(8) Using SST, connect terminals Tc and E
1 of the
DLC1.
SST 09843−18020
(9) Read the number of blinks of the ABS warning light.
HINT:
See the list of DTC on page DI−190 .
If every sensor is normal, a normal code is output (A cycle of
0.25 sec. ON and 0.25 sec. OFF is repeated).
If 2 or more malfunction are indicated at the same time, the low-
est numbered code will be displayed 1st.
