WARNING: This page is about a different car, the 1997 Acura 3.5RL. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Deactivate air bag system before performing any service operation. See AIR BAG RESTRAINT SYSTEM article. All air bag wiring harnesses are covered by Yellow outer insulation. DO NOT use electrical test equipment on these circuits. Do not apply electrical power to any component on steering column without first deactivating air bag system. Air bag may deploy.

CAUTION: When battery is disconnected, radio will go into anti-theft protection mode. Obtain radio anti-theft protection code from owner prior to servicing vehicle.

The cruise control unit receives command signals from cruise control main switch and cruise control SET/RESUME/CANCEL switch. Vehicle operating signals are also received from brakelight switch, Vehicle Speed Sensor (VSS), and gearshift position switch (A/T). Cruise control unit sends control signals to cruise control actuator, which regulates throttle position to maintain selected vehicle speed.

The cruise control unit compares actual vehicle speed to selected speed. Cruise control unit will open or close throttle to change and maintain vehicle speed. When cruise control unit receives a disengage signal, cruise control actuator will allow throttle to close. A signal from the brakelight switch disengages the system when the brakes are applied. Gearshift position switch or cancel switch can also send disengage signals to cruise control unit.

Cruise control actuator is vacuum operated with a magnetic safety clutch and electrically operated vacuum control valves.
