CRUISE CONTROL SYSTEM
1996 LAND CRUISER (RM451U)
INSPECTION PROCEDURE
1
Check resistance between terminals VR2 and VR3 of cruise control ECU connec-
tor.
PREPARATION:
(a)
Remove the ECU with connectors still connected.
(b)
Turn ignition switch OFF.
CHECK:
Measure voltage between terminals VR2 and VR3 of ECU con-
nector while turning control plate slowly by hand from the decel-
eration side to the acceleration side.
OK:
Voltage:
Fully closed: Approx. 1.3 V
Fully opened: Approx. 4.1 V
In addition, as the control plate is turned, the voltage
should increase gradually without interruption.
NG
Proceed to next circuit inspection shown on
problem symptoms table (See page

Check resistance between terminals VR1 and VR3 of actuator position sensor.
PREPARATION:
(a)
Turn ignition switch OFF.
(b)
Disconnect the actuator connector.
CHECK:
