Product Information

This is a diagnostic loom for temporary use with the Webasto Thermo Top C and Z/C fuel burning heaters (FBH) as fitted to Range Rover (L322) and Freelander Mark 1 diesel models as well as some BMW models and aftermarket accessory Webasto heaters.

NOT for Volkswagen/Audi Thermo Top C heaters as they are wired to use PIN 1 for diagnostics, click here for the VW version.

Allows fault finding, component test and heater operation using the Webasto Thermo Test software. See www.disco3.co.uk/fbh for more.

The loom connects to the vehicle battery or a 12V power source (e.g. underbonnet 12V point) with crocodile clips, and to the FBH with an 6 pin plug.

The connection for the OBD adapter required (see below) is provided by an OBD socket, no fiddling with getting pins in the right place on the adapter's plug!

Instructions for fitting the loom are available to download from here: link (PDF) - this is for the TTV fitted to a Discovery 3 but the principle is the same.

Instructions/manual for the Webasto software is available in the wiki: click here

IMPORTANT: to use this loom for diagnostics you ALSO need a simple OBD2 adapter for K-line communications, these are now available from us: click here

Made by us in the United Kingdom.
