Description & Operation
WARNING: This page is about a different car, the 2001 Mitsubishi Eclipse. 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 SYSTEMS article. DO NOT apply electrical power to any component on steering column without first deactivating air bag system. Air bag may deploy.
Cruise control system is electronically-controlled and vacuum-actuated. System components include: cruise control Electronic Control Unit (ECU), vacuum pump, actuator, cruise control switch, cruise indicator light, Park/Neutral (P/N) switch (A/T), clutch pedal switch (M/T), brakelight switch, throttle position sensor and vehicle speed sensor. See Fig 1 .
System has self-diagnostic capability. When self-diagnostic mode is activated, each switch and sensor is checked for faults. If cruise control system has been cancelled without using a normal cancel method, a Diagnostic Trouble Code (DTC) will be set and stored in the cruise control ECU. Codes can be retrieved to help determine which circuit is malfunctioning.
