FEATURES
Engine Brakes in Cruise Control (Optional)
If driving conditions cause the vehicle speed to exceed the Cruise Control set speed, engine brakes
(if configured) are activated to keep the desired road speed based on engine brake dash switches.
Cruise Auto Resume (Optional)
The Cruise Auto Resume feature will resume Cruise Control based on the calibration setting.
1 = Cruise Control is resumed immediately after the clutch pedal is released.
2 = Cruise Control is resumed if the clutch has been pushed twice and released within three
(3) seconds.
Adaptive Cruise (Optional)
Adaptive Cruise systems will send a "heart beat" message on the SAE J1939 Data Link. Manual
Cruise Control and Adaptive Cruise will be disabled if the message is not received over the data
link or the message indicates that there is a failure in Adaptive Cruise. To enable standard Cruise
Control, the driver must toggle the Cruise Master Switch twice within 10 seconds.
Adaptive Cruise uses a third party system to maintain a range between vehicles.
Cruise Enable
Cruise Control is in standby, but not active when the Cruise Control Enable digital input is
switched to battery ground.
The Cruise Enable switch is a normally open switch.
Set / Coast
The Set/Coast switch is a momentary switch.
Set:
Cruise Speed is set by momentarily contacting the switch to the ON position
(switching the digital input to battery ground). Cruise Control will become
active and maintain the vehicle speed present at the time.
Coast: When Cruise Control is active, the Set/Coast input can be used to reduce power
and speed by toggling the switch. Momentarily toggling and releasing the
Set/Coast switch will decrease the set point by 1 mph (1.6 km/h) increments
for Cruise Control. Holding the Set/Coast will decrease the set point by 1 mph
(1.6 km/hr) per second. When released the Cruise Control set point will be
at the current speed.
