Digital Audio Broadcast Module (DABM)

WARNING: This page is about a different car, the 2011 Jaguar XKR, 2011 Jaguar XK, 2010 Jaguar XKR, and 2010 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00

NOTE: If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to the installation of a new module/component.

NOTE: Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by the manufacturer-approved diagnostic system).

NOTE: When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places and with a current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.

NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

NOTE: If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.

The table below lists all diagnostic trouble codes (DTCs) that could be logged in the digital audio broadcast module, for additional diagnosis and testing information. For additional information, refer to: AUDIO SYSTEM .

DTC	Description	Possible Cause	Action
B11A4-11	L-Band Antenna - circuit short to ground	DAB L-Band antenna circuit - short to ground	If DTCs: B11A411, B11A511, U300044, U30004A, U300098, U300362 have logged at the same time with invalid snapshot data carry out a DTC clear and re-read to ensure the DTCs have not re-logged. If the DTC B11A411 does re-log (without the other DTCs) carry out any pinpoint tests associated with this DTC using the manufacturer approved diagnostic system. Refer to electrical circuit diagrams and check DAB L-Band antenna circuit for short to ground.
B11A4-15	L-Band Antenna - circuit short to battery or open	DAB L-Band antenna circuit - short to power, open circuit	Carry out any pinpoint tests associated with this DTC using the manufacturer approved diagnostic system. Refer to electrical circuit diagrams and check DAB L-Band antenna circuit for short to power, open circuit.
B11A5-11	Band 3 Antenna - circuit short to ground	DAB Band 3 antenna circuit - short to ground	If DTCs: B11A411, B11A511, U300044, U30004A, U300098, U300362 have logged at the same time with invalid snapshot data carry out a DTC clear and re-read to ensure the DTCs have not re-logged. If the DTC B11A511 does re-log (without the other DTCs) carry out any pinpoint tests associated with this DTC using the manufacturer approved diagnostic system. Refer to electrical circuit diagrams and check DAB Band 3 antenna circuit for short to ground.
B11A5-15	Band 3 Antenna - circuit short to battery or open	DAB Band 3 antenna circuit - short to power, open circuit	Carry out any pinpoint tests associated with this DTC using the manufacturer approved diagnostic system. Refer to electrical circuit diagrams and check DAB Band 3 antenna circuit for short to power, open circuit.
U3000-04	Control Module - system internal failures	System internal failure	Clear the DTC and perform a system function check. If the DTC re-logs and the system do not function correctly suspect the digital audio broadcast module. Check and install a new module as required.
U3000-44	Control Module - data memory failure	System internal failure	If DTCs: B11A411, B11A511, U300044, U30004A, U300098, U300362 have logged at the same time with invalid snapshot data carry out a DTC clear and re-read to ensure the DTCs have not re-logged.
U3000-4A	Control Module - incorrect component installed	Incorrect component installed	If the DTCs: B11A411, B11A511, U300044, U30004A, U300098, U300362 have logged at the same time with invalid snapshot data carry out a DTC clear and re-read to ensure the DTCs have not re-logged. If the DTC does re-log check/up-date Car Configuration File using manufacturer approved diagnostic system.
U3000-55	Control Module - not configured	Incorrect Car Configuration File data received	Check/up-date Car Configuration File using manufacturer approved diagnostic system.
U3000-87	Control Module - missing message	Missing message	Check RJB for related DTCs and refer to relevant DTC Index. Check information and entertainment module for Car Configuration File and MOST network DTCs and refer to relevant DTC Index. Carry out MOST/CAN network tests using the manufacturer approved diagnostic system.
U3000-98	Control Module - component or system over temperature	Component or system over temperature	If DTCs: B11A411, B11A511, U300044, U30004A, U300098, U300362 have logged at the same time with invalid snapshot data carry out a DTC clear and re-read to ensure the DTCs have not re-logged.
U3003-62	Battery Voltage - signal compare failure	Mis-match in battery voltage, of 2 volts or more, between digital audio broadcast module and RJB	If DTCs: B11A411, B11A511, U300044, U30004A, U300098, U300362 have logged at the same time with invalid snapshot data carry out a DTC clear and re-read to ensure the DTCs have not re-logged. If only DTC U300362 is logged carry out any pinpoint tests associated with this DTC, check power supply circuits to Digital Audio Broadcast module and Rear Junction Box.
