DESCRIPTION
Since the December, 1988 production, the material used for some o f the terminals o f the connector between
the E .C .U . and the engine harness has been changed from gold to tin. In accordance with this design change,
there is no interchangeability between new and old parts regarding the E .C .U . and the engine harness.
If a new E .C .U . is installed using an old engine harness, although the system itself will operate normally,
galvanic corrosion may occur due to the different materials o f the terminal plating. The corrosion at the
terminals may result in poor driveability.
Thus, when you replace an E .C .U . or an engine harness, please be sure to check the generation o f the
parts and use a replacement part o f the same generation.
