When diagnosing electric power steering problems on a number of Jeep, Dodge and Chrysler vehicles, it's imperative that you don't disconnect the gray EPS torque sensor connector on the EPS module.
Example of EPS module. Note the gray connector for the torque sensor.
This bulletin applies to 2014-2017 2017 Jeep Cherokee, 2017 Grand Cherokee vehicles, 2015-2017 Dodge Challenger, Charger, Chrysler 300, Chrysler 200, 2016-2017 Dodge Durango, 2017 Chrysler Pacifica and 2012-2015 Dodge Dart vehicles, equipped with electric power steering. During any EPS module diagnosis, do not disconnect the gray EPS torque sensor connector on the EPS module.
If the torque sensor connector is disconnected, the following scenarios can occur:
If one or two ignition cycles occur while the torque sensor harness is disconnected, DTC C2217-00 will be active in the EPS module. This code can be cleared.
If three or more ignition cycles occur with the torque sensor harness disconnected, DTC C15DB-00 will be active. This code cannot be cleared. The EPS gear will need to be replaced.
