INSPECTION PROCEDURE
1 Input signal check.
CHECK:
(a) See input signal check on page DI−286.
(b) Check indicator light operation when driving with vehicle speed above 40 km/h (25 mph), and with vehicle speed
below 40 km/h (25 mph).
OK:
Vehicle speed above 40 km/h (25 mph):
Indicator light blinks
Vehicle speed below 40 km/h (25 mph):
Indicator light stays on
OK Check and replace cruise control ECU (See page IN−28 ).

Idle Switch Circuit
CIRCUIT DESCRIPTION
When the idle switch in 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 val\
ue 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.
