Driver Information Module (DIM)
The driver information module (DIM) (5/1) receives information from the central electronic module (CEM) about which message is to appear in the display. A message will be displayed if there is a fault in any of the checks run by the system.
For further information, see Design and Function, driver information module (DIM).
The central electronic module (CEM) is the master unit for the immobilizer. The central electronic module (CEM) also directly stores diagnostic trouble codes (DTCs) for faults in the immobilizer system. Some other faults can also be stored in the engine control module (ECM). For information about diagnostic functions, see Design and Function, central electronic module (CEM), and Design and Function, engine control module (ECM).
