Diagnostics







The diagnostic socket allows for the transfer of information between the LCM, the automatic headlamp levelling ECU and TestBook/T4. The diagnostic socket is located in the fascia, in the driver's stowage tray. The socket is secured in the fascia and protected by a hinged cover.

The LCM has diagnostic capabilities and store 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, located on the rear of the headlamp assemblies, can be interrogated using TestBook/T4 for faults relating to the operation of the xenon lamps. The control modules are connected on a DS2 link to the diagnostic socket.
