Cruise Control

The Cruise Control Module sends the cruise status input to the PCM to indicate when cruise control is engaged.

The PCM monitors the cruise status signal while commanding cruise to be disengaged via the cruise inhibit circuit. Any of the following conditions may cause the PCM to inhibit cruise control operation:

The cruise control module terminal K is the vehicle speed signal input terminal through circuit 817. In operation, the voltage varies between 0.0-5.0 volts. The cruise control module terminal J is used to signal the Powertrain Control Module (PCM) when cruise control is engaged through circuit 85. The PCM will then determine the correct shift pattern for the transmission. The cruise control module terminal H is used by the PCM through circuit 83, to inhibit cruise control when conditions inconsistent with cruise operation are present.

The PCM will inhibit cruise control under the following conditions:
^ When vehicle speed is less than 40 km/h (25 mph).
^ When PARK, REVERSE, NEUTRAL, or 1st gear is indicated by the transaxle range switch.
^ When an over/under battery voltage condition exists.
^ With low engine RPM.
^ With high engine RPM (fuel cut-off).
^ ABS system is active for longer than 2 seconds.
