Issues with Cruise Adaptive Relearn. Cruise does not engage
Have replaced Cruise Control Switch, checked fuses and reprogrammed Cruise Control Module.
When starting cruise control relearn, green vehicle light on dash flashes, then goes off.
When you try to set cruise speed, nothing happens.
Most vehicles have pids for cruise control inhibited. Usually a list of them.
Axis alignment/calibration dtc's? Adaptive cruise is different from cruise control. Forward radar/windshield camera.
… Any LED Bulbs installed… I knocked out my cruise operation on my '02 Avalanche by putting those in it… had to add resistors to restore operation (and slow blink rate too)… Dan H.
Had a Cadillac CTS with same issue. Had been in a front end accident (actually right front fender & headlight). Managed to damage the cruise control module also. Body shop installed a new module & I programmed it. Didn't work... won't do the calibration re-learn. Had to take off the grill & align the cruise control module as bracket was bent. Worked fine after that.
