don't think you need DOZ to get the car to run on automatic. probably something else .
the power supply molex connector can be a problem, make sure all the voltages are good, 5v + and - 12, J7 from the power supply to J1 on controller. no ac ripple
Im almost certain you do not need DOZ for car to run on automatic, only to relevel with stop switch or doors open like IDWT indicates. keep us posted.
