B-1 Code L202 With L203, L206 or L210

ADDRESSING PROBLEM
Code L202, along with L203, L206, or L210 indicates, a loss of power to an OSM address pin. When such an addressing failure exists on pin F of OSM # 3, pin D of OSM # 6, or pin C of OSM # 10, its address becomes the same as that of OSM # 2. Therefore, when the Body Control Module (BCM) sends a command on the data line to OSM # 2, both OSM # 2 and the misaddressed OSM try to respond resulting in a lighting fault. During such an addressing failure, when the BCM sends a command to the misaddressed OSM, a lighting fault occurs because there isn't an OSM available to respond to the command. The table below lists the Computer Control Driver Information Center (CCDIC) messages and symptoms of these conditions.
