SystemSupplierId (SYSSUPPID)
R
ASCII
9
This DID contains SystemSupplierId information which identifies the ECU hardware supplier and the
system type (System Group Identifier). The SYSSUPPID also contains a 2-character reserved field for
future definition. The SYSSUPPID must be stored in the ECU in a 
non-erasable memory area (e.g.,
boot sector of flash, or EEPROM)
. It shall not be possible to change the SYSSUPPID during a
programming session or via normal diagnostic services. The SYSSUPPID consists of a structured
sequence of nine ASCII characters which conform to GM-SPS (GM Service Programming System)
requirements.
1. System Supplier Identifier (5 ASCII characters) (e.g., GM Powertrain = GMPT, DELCO = DELCO;
SIEMENS = SIEM; BOSCH = BOSCH)
Note: 
For GM Powertrain and Siemens, the 5
th 
ASCII character in this field shall be a space ($20).
2. System Group Identifier (2 ASCII characters):
00=Powertrain, 01 = Engine, 02 = Transmission, 03 = Chassis, 04 = Body, all others reserved by
document (RBD).
3. Reserved area (Two ASCII characters)

This DID contains the SystemNameOrEngineType which identifies the electronic system name (e.g.,
Automatic Transmission with 2 liter engine: GS820 X20XEV) or engine type (X30XE) installed. The data
shall always be of type ASCII. The length is variable (depends on length of string) but shall not exceed
20 characters.
