For 1990-2009 cars

The powertrain control module (PCM) has the ability to set a diagnostic trouble code (DTC) and store failure record information when the cruise control ON/OFF switch is cycled three times within a 3 second period. The intended purpose of this DTC is to allow the customer to capture failure record information during a driveability condition that may be difficult to duplicate during a test drive. The technician can use this information to attempt to simulate the engine operating conditions the vehicle was under at the time the driveability condition occurred. This feature is on cruise control vehicles only.
