INSPECTION PROCEDURE
1 Check voltage between terminals VR2 and VR3 of ECU connector.
PREPARATION:
Remove ECU with connectors still connected.
CHECK:
(a) Turn ignition switch ON.
(b) Measure voltage between terminals VR2 and VR3 of
ECU connector while turning control plate slowly by hand
from the deceleration side to the acceleration side.
OK:
Voltage:
Fully closed: approx. 1.3 V
Fully opened: approx. 4.0 V
Note: As the control plate is turned, the voltage
should increase gradually without interruption.
OK Proceed to next circuit inspection shown on
matrix chart (See page DI−336).

PREPARATION:
(a) Remove cruise control actuator.
(b) Disconnect the actuator connector.
CHECK:
Measure resistance between actuator terminals 1 and 3 of ac-
tuator connector.
OK:
Resistance: Approx. 2.2 kΩ
CHECK:
Measure resistance between terminals 2 and 3 of actuator con-
nector, while turning the control plate slowly by hand from the
deceleration side to the acceleration side.
OK:
Resistance:
Fully closed: Approx. 530 kΩ
Fully opened: Approx. 2.0 kΩ
Note: As the control plate turns, the resistance
should increase gradually without interruption.
NG Replace actuator assembly.
OK
3 Check for open and short in harness and connector between ECU and actuator
position sensor (See page IN−30).
NG Repair or replace harness or connector.
OK
Check harness and connector for loose con-
nection. If connection is normal check and
replace ECU.
