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 stalling have been attributed to early releases of the MC1000 ECU
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 condition 1 above, a revised version 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 proce-
dure.”
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 prerequisite to performing any work. Consult the kit documentation for more details.
