U0182Lost Communication With Lighting Control Module Front
- Generic OBD-II code · Network
- How the car detects it
- U0182 is logged when the front lighting control module stops talking on the bus. This module drives front lamp functions such as swivelling or adaptive beam patterns. GM lists it as Lost Communication With Lighting Control Module - Front in the Saab 9-5 (2010-2011) U-code list. Chrysler uses it for the adaptive front lighting module: a 2014 Jeep Grand Cherokee field report filed with NHTSA shows U0182-00 Lost Communication With Adaptive Front Lighting Control Module next to other network codes. GM's logic: the code sets when the module's supervised periodic message stops arriving at 9-16 V. U0181 is the headlamp levelling module, U0183 the rear lighting module. No MIL; cornering or adaptive light may fall back to a basic beam.
