This bulletin applies to 2014-2017 Jeep Cherokee vehicles equipped with EPS (electric power steering).
During EPS module electrical diagnosis and verification, do not disconnect the gray EPS torque sensor connector on the EPS module. If the torque sensor connector is disconnected, the following scenarios can take place:
If one or two ignition cycles occur while the torque sensor harness is disconnected, diagnostic trouble code (DTC) C2217-00 will be active in the EPS module. This code can be cleared.
If three or more ignition cycles occur while the sensor is disconnected, DTC C15DB-00 will be active. This code cannot be cleared and the EPS gear will need to be replaced.
Disconnecting the torque sensor harness while the EPS module is off the vehicle and not powered up will not generate any DTCs.
