DTC P1526 Minimum Throttle Position Not Learned This is due to the many redundant tests run continuously on this system. Testing for Intermittent Conditions and Poor Connections P1568 Cruise Servo Stroke Greater than Commanded in Cruise This occurs because 1 set of the transistors are low, 0volts, and the other set On high current power circuits, this condition may cause permanent increases in the resistance and may cause a device to become inoperative. Locating and repairing an individual condition may correct more than 1 DTC. Immediately after delivery, I discovered a clean diagnostic memory in all modules, which was especially odd since 40 engine warm-up cycles are required to erase the ever-present P1518. DTC P1653 Oil Level Lamp Control Circuit Clearly, the TAC module was dropping into a Reduced Power mode. DTC P1586 Cruise Control Brake Switch 2 Circuit I had the car towed to my house where it has sat for two weeks. This should fix your problem. Refer to The car will not start now.
