Sprinter 2500 V6-3.0L DSL Turbo VIN 45 (2007)
sends the proper lamp-ON or lamp-OFF messages to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment
Node/CCN or KOMBI). If the CAB sends a lamp-ON message after the bulb test, it indicates that the CAB has detected a system malfunction or that the
ASR system or the BAS system has become ineffective. The CAB will store a Diagnostic Trouble Code (DTC) for any malfunction it detects.
For proper diagnosis of the ASR or BAS system, the CAB, the EMIC, the CAN data bus or the electronic communication related to ASR/BAS indicator
operation, a diagnostic scan tool is required. Refer to the appropriate diagnostic information.
