Do this vehicule have to do updates with the dodge dealer because my customer didn't receive a recall compaign.
My husband say something more about this problem : when he try to put off the error light on dash board, it is impossible to turn off
Expert:  Todd M replied 1 month ago.

There is no recall or update for this issue. As far as the light, it will not turn off until the issue is solved, which will likely be a communication issue with the ECU or the ABS module. He can test the connections to be sure they are secure. Also, inspect the wiring for damage. If there is no damage, then he will have to have the ECU inspected and replaced as necessary.
