MIL Illumination - DTC P0300 - Service Action S659
ISSUE:
Some 1996 MY vehicles within the above VIN range may experience illumination of the Malfunction Indicator Lamp (MIL) caused by DTC P0300
being set. The DTC is set due to close software tolerances in the ECM rather than a mechanical problem with the engine.
This condition can be rectified by replacing one or both of the Programmable Read Only Memories (PROMs), depending on the VIN, with new PROM
(s) from the appropriate modification kit.
ACTION:
