Fail safe function:
If trouble occurs in the power source circuit, the ECU cuts off current to the ABS control (solenoid) relay and
prohibits ABS control.

(Reference value 80 Ω)
Terminals A9−5 and A9−6Continuity
Terminals A9−2 and A9−5Open
CHECK:
(a) Apply battery voltage between terminals A9−1 and A8−3.
(b) Check the continuity between each terminal of the ABS
control relay.
OK:
Terminals A9−5 and A9−6Open
Terminals A9−2 and A9−5Continuity
CHECK:
Connect the  test lead to terminal A9−4 and the  lead to ter-
minal A9−5. Check the continuity between the terminals.
OK:
Continuity
If there is no continuity, connect the  test lead to ter-
minal A9−4 and the  lead to terminal A9−5. Recheck
the continuity between the terminals.
NG Replace ABS control relay.
OK
Check for open in harness and connector between DLC1 and ABS control relay and body ground
(See page IN−30).

HINT:
When 2 or more codes are indicated, the lowest numbered code will be displayed first.
If the inspection ”Proceed to next circuit inspection shown on matrix chart” is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue check.
If the trouble still reappears even though there are no abnormalities in any of the other circuits, then
check or replace the cruise control ECU as the last step.
(*) When the vehicle speed decrease on uphill roads, the speed can be set again and driving continued. (This
is not a malfunction.)

INSPECTION PROCEDURE
1 Check actuator motor.
PREPARATION:
(a) Remove cruise control actuator.
(b) Disconnect actuator connector.
CHECK:
(a) Connect positive + lead to terminal 5 and negative − lead
to terminal 4 of actuator connector (Magnetic clutch ON).
NOTICE:
Do not connect the high tension cables to the wrong bat-
tery terminal.
You will damage the cruise control actuator.
(b) When battery positive voltage is applied to each terminal
of actuator connector, check that the control plate moves
smoothly without hesitating.

(c) With the motor rotating as in 2., check that the motor is
stopped by limit switches when the control plate moves to
fully opened or fully closed position.
NG Replace actuator assembly.
OK
2 Check harness and connector between cruise control ECU and actuator motor
(See page IN−30).
NG Repair or replace harness or connector.
OK
Proceed to next circuit inspection shown on matrix chart (See page DI−336).
However, when DTC 11, 14 is displayed, check and replace cruise control ECU.

Stop Light Switch Circuit
CIRCUIT DESCRIPTION
When the brake is on, battery positive voltage normally applies through the stop fuse and stop light switch
to terminal STP− of the ECU, and the ECU turns the cruise control off.
A fail−safe function is provided so that cancel functions normally, even if there is a malfunction in the stop
light signal circuit.
If the harness connected to terminal STP− has an open, terminal STP− will have battery positive voltage and
the cruise control will be turned off, also SET not occurring.
Also, when the brake is on, the magnetic clutch is cut electrically by the stop light switch, turning the cruise
control off. (See page DI−338 for operation of the magnetic clutch)
