DIAGNOSTICS
CRUISE CONTROL SYSTEM
1996 LAND CRUISER (RM451U)
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 value 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.
