Fixing Chrysler's Blind Spot Monitor
2013 Chrysler Grand Voyager/Town and Country vehicles built between April 22, 2012 and Dec. 22, 2012 may have an issue with Blind Spot and Cross Path Detection (if so equipped).
The customer may experience the blind spot indicator in either outside mirror flashing or on continuously. The technician may find no DTCs. Using a scan tool, verify that no Blind Spot Monitor DTCs are present. Reprogramming is necessary. Install a battery charger to prevent battery voltage from dropping below 13.2 volts or rising above 13.5 volts during the flash.
Using wiTECH, check the part number of the LBSS and RBSS. If the part number ends with “AB,” flash reprogram the LBSS and RBSS. Using software level release 13.03 or higher.
