System description
This system is controlled by the ecm, and is activated by the throttle position sensor and motor. The ecm controls the following functions: on-off, set / coast, resume / accel, cancel, vehicle speed operation, motor output control, and overdrive control.
Cruise control operation will be automatically canceled when the vehicle speed decreases below the low speed limit 40 km/h (25 mph) while the cruise control is in operation.
Also, +/res cannot be used to increase speed beyond the high speed limit.
The cruise control switch operates 7 functions: set, coast, tap-down, resume, acceleration (accel), tap-up, and cancel. The set, tap-down and coast functions, and the resume, tap-up and accel functions are operated with the same switch.
The cruise control switch is an automatic return type switch which turns on only when pressed in each arrow direction and turns off when released.
vehicle speed is stored and constant speed control is maintained when pushing the switch to -/set while driving with the cruise control switch on (the cruise main indicator light is illuminated), and the vehicle speed is within the set speed range (between the low and high speed limits).
The ecm changes the cruise control demanding throttle opening angle to 0Рand decelerates the vehicle when -/set on the cruise control switch is pressed and held while the cruise control system is operating. When the cruise control switch is released from -/set, the vehicle speed is stored and constant speed control is maintained.
Hint:
When tapping down the cruise control switch to -/ set (for approximately 0.5 Seconds) while the cruise control system is in operation, the stored vehicle speed decreases each time by approximately 1.6 Km/h (1.0 Mph). When the cruise control switch is released from -/set and the difference between the driving and stored vehicle speed is less than 5 km/h (3 mph), the vehicle speed is stored and constant speed control is maintained.
The throttle valve motor of the throttle position sensor and motor is instructed by the ecm to open the throttle valve when +/res on the cruise control switch is pressed and held while the cruise control system is operating. When the cruise control switch is released from +/res, the vehicle speed is stored and constant speed is maintained.
When tapping up the cruise control switch to +/res (for approximately 0.5 Seconds) while the cruise control system is in operation, the stored vehicle speed increases each time by approximately 1.6 Km/h (1.0 Mph). However, when the difference between the driving and the stored vehicle speed is more than 5 km/h (approximately 3.1 Mph), the stored vehicle speed will not be changed.
If the cruise control operation was canceled with the stop light switch or the cancel switch, and if driving speed is within the set speed range, setting the cruise control switch to +/res restores the vehicle speed memorized at the time of cancellation, and constant speed is maintained.
Performing any of the following cancels the cruise control system (the stored vehicle speed in the ecm is maintained).
This system has an automatic cancellation function (failsafe) (see page cc-17).
Driving position memory
Your preferred driving position (the position of the driver’s seat) can
be recorded and recalled by pressing a button.
Two different driving positions can be recorded into memory.
Recording procedure
Check that the shift lever is in p.
Turn the engine switch to the “on” position (ve ...

Driver side - side airbag sensor circuit malfunction
Description
The side airbag sensor lh consists of part including the diagnostic circuit
and the lateral deceleration
sensor.
When the center airbag sensor receives signals from the lateral deceleration
sensor, it determines
whether or not the srs should be activated.
