Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Gateway Module
The gateway module is located in the LH (left-hand) side of the luggage compartment.
The gateway module translates MOST signals from the digital radio module (SDARS, DAB or IBOC/HD) to D2B signals for the IHU. The gateway module also steams audio from the digital radio module to the IHU.
The gateway module appears as a slave module on the D2B bus and a master on the MOST bus. The gateway module incorporates basic ring break diagnostics and stores fault codes from the digital radio module. The fault codes can be retrieved by the recommended Jaguar diagnostic tool.
