Stop Light Switch Circuit
CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling, while driving in lock−up condition, when
brakes are suddenly applied.
When the brake pedal is operated, this switch sends a signal to ECM. Then the ECM cancels of the lock−up
clutch while braking is in progress.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check operation of stop light.
CHECK:
Check if the stop lights go on and off normally when the brake pedal is operated and released.
NG Check and repair stop light circuit.

2. SPEED SENSOR SIGNAL CHECK
(a) Check the speed sensor signal.
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminals Ts and E1 of the
DLC1.
SST 09843−18020
(3) Start the engine.
(4) 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−275).
(5) Drive vehicle straight forward.
HINT:
Drive vehicle faster than 45 km/h (28 mph) for several seconds.
(6) Stop the vehicle.
(7) Using SST, connect terminals Tc and E1 of the
DLC1.
SST 09843−18020
(8) Read the number of blinks of the ABS warning light.
HINT:
See the list of DTC shown on the next page.
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 malfunctions are indicated at the same time,
the lowest numbered code will be displayed 1st.
(9) After doing the check, disconnect terminals Ts and
E1, and Tc and E1 of the DLC1, and turn the ignition
switch OFF.

INSPECTION PROCEDURE
1 Is DTC output?
Check DTC on page DI−234.
YES Repair circuit indicated by code output.
NO
2 Is normal code displayed?
YES Check ABS solenoid relay. Check for short in
harness and connector between ABS solenoid
relay and DLC1 (See page IN−30).
NO
3 Is ABS warning light go off?
YES Check for open or short in harness and connec-
tor between ECU−IG Fuse and ECU (See page
IN−30).
NO
4 Check battery positive voltage.
PREPARATION:
Start the engine.
CHECK:
Check the battery positive voltage.
OK:
Voltage: 10 − 16 V
NG Check and repair charging system.

Ts Terminal Circuit
CIRCUIT DESCRIPTION
The sensor check circuit detects abnormalities in the speed sensor signal which cannot be detected with
the DTC check. Connecting terminals Ts and E1 of the DLC1 in the engine compartment starts the check.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check voltage between terminals Ts and E1 of DLC1.
PREPARATION:
(a) Turn the ignition switch ON.
(b) Measure the voltage between terminals Ts and E1 of the
DLC1.
OK:
Voltage: 10 − 14 V
OK If ABS warning light does not blink even after Ts
and E1 are connected, ECU may be defective.

4. INPUT SIGNAL CHECK
HINT:
(1) For check No.1 − No.2.
Turn the ignition switch ON.
(2) For check No.3.
Turn ignition switch ON.
Shift to D position. (A/T Vehicle)
(3) For check No.4.
Jack up the vehicle.
Start the engine.
Shift to D position. (A/T Vehicle)
(a) Press the control switch to the SET/COAST or RES/ACC
position and hold it down or hold it up (1).
(b) Push the main switch ON (2).
(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.
HINT:
When 2 or more signals are input to the ECU, the lowest num-
bered code will be displayed first.

Idle Switch Circuit
CIRCUIT DESCRIPTION
When the idle switch is turned ON, a signal is sent to the ECU. The ECU uses this signal to correct the dis-
crepancy between the throttle valve position and the actuator position sensor value to enable accurate
cruise control at the set speed. If the idle switch is malfunctioning, problem symptoms also occur in the en-
gine, so also inspect the engine.
