SMR2003-026_08-02A.FM
The complete electrical system is managed by
micro-controllers working together. Overall, the
MPEM (multi-purpose electronic module) manag-
es the vehicle electrical system, the EMS (engine
management system) controls the engine man-
agement and the information center is used to dis-
play information that comes both from MPEM and
EMS.
A communication link is used between the elec-
tronic modules to communicate with each other.
It consists of a twisted pair of wires (WHITE/RED
and WHITE/BLACK).
For communication link troubleshooting, refer to
INSTRUMENTS AND ACCESSORIES in ELECTRI-
CAL section.
The communication link is also used to communi-
cate informative messages, monitoring and diag-
nostic codes to the information center and to the
VCK (vehicle communication kit) where B.U.D.S.
(Bombardier utility and diagnostic system) is used
for diagnosing and troubleshooting the system.
The fault code can be seen from either the infor-
mation center or B.U.D.S. Refer to DIAGNOSTIC
PROCEDURES section.
