Understanding GMDAT Vehicle Global Build Variations

TECHNICAL SERVICE BULLETIN

Reference Number(s): 05-06-04-051, Date of Issue: August 18, 2005

Affected Model(s):

2004-2005 Chevrolet Aveo, Epica, Optra, Spark, Vivant; 2004-2005 Pontiac Matiz, Wave

SERVICE INFORMATION

GMDAT vehicles are built for over 100 countries. Different powertrains and emissions drive unique build configurations that result in different Engine Control Module (ECM) usage. This bulletin will aid the technician in identifying which ECM, transmission, and emission package is equipped on the vehicle that they are servicing. This identification is crucial in selecting the proper schematics, diagnostics and repair procedures in Service Information (SI).

IMPORTANT: Technicians in North America should refer to the ULEV (Ultra Low Emissions Vehicle) emission package for the vehicles that they are servicing.
