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 E
1 of the DLC1 in the engine compartment starts the check.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check voltage between terminals Ts and E1 of DLC1.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure voltage between terminals Ts and E
1 of DLC1.
OK:
Voltage: 10 ± 14 V
OK If ABS warning light does not blink even after Ts
and E
1 are connected, the ECU may be defec-
tive.

(d) Inspect the CANCEL switch.
(1) Push the main switch ON.
(2) Drive at a desired speed (40 km/h (25 mph) or high-
er).
(3) When operating one of the following operations,
check that the cruise control system is cancelled
and that the normal driving mode is reset.

Depress the brake pedal

Shift to except D position

Push the main switch OFF

Pull the cruise control switch to CANCEL
(e) Inspect the RESUME switch.
(1) Push the main switch ON.
(2) Drive at a desired speed (40 km/h (25 mph) or high-
er).
(3) When operating one of the following operations
check that the cruise control system is cancelled
and that the normal driving mode is reset.

Depress the brake pedal

Shift to except D position

Push the main switch OFF

Pull the cruise control switch to CANCEL
(4) After the control switch is turned to RES/ACC at the
driving speed of more than 40 km/h (25 mph), check
that the vehicle restores the speed prior to the can-
cellation.

HINT:
(1): For check No.1 ± No.3

Turn ignition switch ON.
(2): For check No.4

Jack up the vehicle.

Start the engine.

Shift to D position.
(a) Pull the control switch to SET/COAST or RES/ACC posi-
tion and hold it down or 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.
