Diagnostics
The diagnostic socket allows for the transfer of information between the LCM and T4.The diagnostic socket is located in the instrument panel, in the driver's stowage tray. The socket is secured in the instrument panel and protected by a hinged cover.
The LCM has diagnostic capabilities and stores fault codes relating to the lighting systems. The xenon control modules cannot be interrogated via the LCM, but the LCM incorporates xenon specific diagnosis up to the control modules.
The xenon control modules on 2006MY vehicles have no diagnostic functionality.
