This TSB applies to 2008-2010 Dodge Charger and Magnum police cars. Police package WIG-WAG lighting, along with other Police inputs (horn mute, radio mute, panic alarm mute) may become inoperative. This condition will most likely occur when the vehicle is in transition from ignition OFF to ignition ON and battery voltage drops below 9 volts.
Using a scan tool (wi-TECH or StarSCAN) with the appropriate diagnostic procedures available on TechCONNECT, verify that all systems are functioning as designed. If DTCs are present, record them and repair as needed before proceeding further.
NOTE: There will be two flash files available. Use the “2008-2010 LX PTIM POLICE” flash file.
