Hello,
I have a 99 Grand Cherokee V8. It recently dropped into limp home mode, and I pulled the code P1698...."Bus communication failure to PCM. A “Companion DTC” was set in both the ECM and PCM"
Does anyone know if this requires that the ECM or TCU be replaced? If so, any help on the location of the parts would be appreciated. Thanks.
