MC1

CONDITION : This service bulletin addresses two conditions identified individually below. Both conditions concern the

engine management system of affected vehicles. (1) Field reports of intermittent engine sta lling hav e been att ri but ed to ea rly re lea se s of the MC1000 E CU

operating code. The operating code is something like the operating system in an ordinary personal computer or PC (example: Windows 95). The operating code should not be confused with the calibration file; that file contains mapping and vehicle specific calibrations. . (2) Field reports indicate hard starting and/or difficult cold starting experiences. These experiences have been attributed to the cold starting “strategies” programmed in early releases of the calibration files on affected units. A calibration file is something like the software running on a particular operating system (example: MS Excel or Word).

SOLUTION : (1) For condit ion 1 above, a revised ver sion of the MC1000 operating code has been developed and must

be installed on all affected models. A special MS-DOS program has been developed to install the revised code file to the vehicle ECU.

(2) A new calibration file has been developed and should be installed into the vehicle ECU after the revised operating code (Condition (1) above) has been installed.

This service bulletin includes step-by-step instructions to correct both conditions in the same “work procedure.”

PARTS : The kit (P/N 912-5001986) including PC software programs, a data cable, and user manuals is necessary

to perform the instructions of this service bulletin. The kit has been shipped to dealerships. The software installation is a prerequisi te to per fo rm in g any wo rk. Consult t he kit documentation for more details.
