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)

Idle Switch Circuit
CIRCUIT DESCRIPTION
When the idle switch is 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.

Electronically Controlled Transaxle Communication Circuit
CIRCUIT DESCRIPTION
When driving uphill under cruise control, in order to reduce shifting due to ON−OFF overdrive operation and
to provide smooth driving, when down shifting in the electronically controlled transaxle occurs, a signal to
prevent upshift until the end of the uphill slope is sent from the cruise control ECU to the electronically con-
trolled transaxle.
Terminal ECM of the cruise control ECU detects the shift change signal (output to electronically controlled
transaxle No.2 solenoid) from the electronically controlled transaxle.
If vehicle speed down, also when terminal electronically controlled transaxle of the cruise control ECU re-
ceive down shifting signal, it sends a signal from terminal OD to OD1 to cut overdrive until the end of the
uphill slope, and the gear shifts are reduced and gear shift points in the electronically controlled transaxle
are changed.

Park/Neutral Position Switch Circuit
CIRCUIT DESCRIPTION
When the shift position is put in except D position, a signal is sent from the park/neutral position switch to
the ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

INSPECTION PROCEDURE
1 Check operation of starter.
CHECK:
Check that the starter operates normally and that the engine starts.

Clutch Switch Circuit
CIRCUIT DESCRIPTION
When the clutch pedal is depressed, the clutch switch sends a signal to the cruise control ECU, when this
signal is input to the cruise control ECU during cruise control driving, the cruise control ECU cancels cruise
control.
