One problem related to ignition module has been reported for the 2001 Nissan 200SX. The most recently reported issues are listed below.
This car was ruled a lemon. Mbusa admitted there is a computer malfunction they do not know how to fix that prevents the passenger mirror from returning to it's memorized postition after it tilts down when the car is in reverse. The remote key (I had it replaced twice) randomly fails to lock and unlock the vehicle. It once randomly locked me in. The passenger doors also unlock when they are not supposed to. The seat also failed to retain memory and I could not reach the pedals unless I corrected it. It continued to malfunction after the control unit was replaced. This car had many random electrical problems. I hope this is helpful.
