Circuit Operation

1. The Set Cruise feature requires the operator to set the initial set speed by using the set/coast button before the resume/accel slider switch input will be recognized whenever the cruise is turned OFF or the ignition switch is closed.
2. The Brake Cruise feature requires the cruise module to see terminal D change states once each ignition cycle before allowing the cruise control to operate. Some cruise modules will use either D or G.
3. Verify that the cruise control module linkage is connected and moving freely.
4. Inspect the cruise cable adjustment. Refer to Cruise Control Cable Adjustment. Cruise Control Cable Adjustment
5. Verify that CKT 17, CKT 1320 and the stoplamps are working properly. If the components are inoperative, the cruise control module will be disabled.
6. The cruise performance can be affected by trailer towing and steep grades.
