Standard definition

Lost Communication with 4WD Clutch Control Module

This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.

In plain English

The 4WD Clutch Control Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Electronically controlled four-wheel-drive engagement is unavailable. Typical causes are loss of power or ground at the module, an open or shorted CAN/LIN bus wire, a connector fault, or an internal module failure.

A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
