Digital Audio Broadcast Module (DABM)

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 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system)

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

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

NOTE: Inspect connectors for signs of water ingress, and pins for damage and/or corrosion

NOTE: If diagnostic trouble codes 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

NOTE: Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the manufacturers approved diagnostic system

The table below lists all diagnostic trouble codes (DTCs) that could be logged on the digital audio broadcast module, for additional diagnosis and testing information refer to the relevant diagnosis and testing section. For additional information, refer to: DIAGNOSIS AND TESTING .

B11A4-15	L-Band Antenna - circuit short to battery or open	Digital audio broadcast L-band antenna circuit - short circuit to power, open circuit, high resistance	Refer to electrical circuit diagrams and check digital audio broadcast L-band antenna circuit for short circuit to power, open circuit, high resistance
B11A5-11	Band 3 Antenna - circuit short to ground	Digital audio broadcast band 3 antenna circuit - short circuit to ground	Refer to electrical circuit diagrams and check digital audio broadcast band 3 antenna circuit for short circuit to ground
B11A5-15	Band 3 Antenna - circuit short to battery or open	Digital audio broadcast band 3 antenna circuit - short circuit to power, open circuit, high resistance	Refer to electrical circuit diagrams and check digital audio broadcast band 3 antenna circuit for short circuit to power, open circuit, high resistance
U3000-04	Control Module - system internal failures	System internal failure	Clear the diagnostic trouble code and retest. If the diagnostic trouble code persists, check and install a new digital audio broadcast module, as required. Refer to the warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new module
U3000-44	Control Module - data memory failure	System internal failure	Clear the diagnostic trouble code and retest. If the diagnostic trouble code persists, check and install a new digital audio broadcast module, as required. Refer to the warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new module
U3000-4A	Control Module - incorrect component installed	Incorrect digital audio broadcast module installed The module has been installed to a vehicle not configured to accept it	Using the manufacturer approved diagnostic system select the vehicle configuration main menu, select configure existing modules menu and re-program the module. Clear the diagnostic trouble code and retest If the diagnostic trouble code persists, check and install a new digital audio broadcast module, as required. Refer to the warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new module
U3000-55	Control Module - not configured	Incorrect car configuration file data received	Using the manufacturer approved diagnostic system select the vehicle configuration main menu, select configure existing modules menu and re-program the module. Clear the diagnostic trouble code and retest If the diagnostic trouble code persists, check and install a new digital audio broadcast module, as required. Refer to the warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new module
U3000-87	Control Module - missing message	Missing message	Using the manufacturer approved diagnostic system select the vehicle configuration main menu, select configure existing modules menu and re-program the module. Clear the diagnostic trouble code and retest Refer to the electrical circuit diagrams and check the MOST network connections to the module
U3000-98	Control Module - component or system over temperature	Component or system over temperature	Check that the digital audio broadcast module cooling vents/air circulation is not obstructed Cool the vehicle interior down by ensuring it is in the shade and have the A/C on cool. When cool, clear the diagnostic trouble code and retest. If the problem persists, renew the digital audio broadcast module. Refer to the warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new module
U3003-62	Battery Voltage - signal compare failure	Digital audio broadcast module voltage differs more than ±2V compared to central electronics module voltage	Refer to relevant information and battery care manual. Check battery state of charge and starting/charging system performance Refer to electrical wiring diagrams and check the power and ground circuits to the digital audio broadcast module. Repair wiring harness as required. Clear diagnostic trouble code and retest
