Cruise Control issues - 2001 Nissan Maxima SE

I've got a 2001 SE with about 47,000 miles on it. I'm having issues with the cruise control. When I set the speed, I experience several different problems

  1. The car will simply slow down and the SET light will turn off. or
  2. For a second the car will hold the speed, accelerate a little and then slow down and the SET light will turn off again. or
  3. The car will slow, downshift and accelerate slowly and then the "SET" like will turn off.

I visually checked the cruise control servo under the hood..nothing obvious there. I then turned to the PCM to see if it would output any trouble codes (maybe the speed sensor is bad) however I could not find the mode selector on the PCM. On previous years, you'd take off the plastic cover next to the gas pedal to find the mode selector, however its not there.

Any idea if this type of test is still available on the 01 Maxima's? I also checked to see if I could find a DLC that might allow me to interface a scanner tool but I couldn't locate that either.

Thanks for your help!

You need an OBD-II scan tool starting with the 2K model. The connector is under dash below and, I believe, to the left of the steering wheel. BTW, unless you live in California, any Autozone can/will pull any codes for you for free. But unless the CEL is on, there's no code to pull and I don't believe there are any codes for the cruise control system anyway. Look for a loose/disconnected/pinched vacuum hose.

Not all trouble codes trigger the CEL.

Patrick,

If it isn't a vacuum leak, maybe it's a problem with the ASCD pump or actuator. They have diagnostic procedures in the factory service manual that might pinpoint it for you.

Nice, I had forgot about the automatic speed control device in the dash. I'll give that a look see. I think I have some doc's on doing some basic on-board diagnostics of the ASCD.

Thanks,

Patrick

They have
