Introduction, Dealer Responsibitily and Parts Information

All 1988 California model vehicles are equipped with a Check Engine Light which will come ON if the engine control unit (E.C.U.) detects improper operation of a monitored system. Under certain driving conditions, the light may come ON and the E.C.U. may have a malfunction code for the E.G.R. system (Code 32) even though the system is operating properly. A special sub-harness has been produced to correct this incident, and a Special Service Campaign is being conducted to install this harness.

All owners of the affected vehicles will be notified by letter to bring their vehicles to a Nissan dealership for installation of the harness. The harness will be sent to the owner along with the letter.
