Satellite Radio Module (SARM)

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 satellite radio module, for additional diagnosis and testing information refer to the relevant diagnosis and testing section. For additional information, refer to DIAGNOSIS AND TESTING .

DTC	Description	Possible Cause	Action
B1A89-01	Satellite Antenna - general electrical failure	Wiring harness fault - Coaxial cable between satellite radio module and the satellite antenna Internal electronic failure - Satellite digital audio radio antenna Internal electronic failure - Satellite radio module	Refer to the electrical circuit diagrams and check satellite digital audio radio antenna coaxial cable for short circuit to ground, short circuit to power, open circuit, high resistance. Repair wiring harness as required, clear DTC and retest If fault persists, check and install a new satellite digital audio radio antenna If fault persists, check and install a new satellite radio 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/component
B1A89-11	Satellite Antenna - circuit short to ground	Satellite antenna circuit - short to ground	Refer to the electrical circuit diagrams and check satellite antenna circuit for short circuit to ground. Repair wiring harness as required. Clear DTC and retest
B1A89-12	Satellite Antenna - circuit short to battery	Satellite antenna circuit - short to power	Refer to the electrical circuit diagrams and check satellite antenna circuit for short circuit to power. Repair wiring harness as required. Clear DTC and retest
B1A89-13	Satellite Antenna - circuit open	Satellite antenna circuit - open circuit, high resistance	Refer to the electrical circuit diagrams and check satellite antenna circuit for open circuit, high resistance. Repair wiring harness as required. Clear DTC and retest
U3000-04	Control Module - system internal failures	System internal failure	Check and install a new satellite radio 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/component
U3000-4A	Control Module - incorrect component installed	Satellite radio module - Incorrect component installed Car configuration mismatch	Using the manufacturer approved diagnostic system select the vehicle configuration main menu>vehicle configuration>display and modify the vehicle configuration file data Check update as required
U3000-55	Control Module - not configured	Satellite radio module - Incorrect component installed Incorrect car configuration file data received	Using the manufacturer approved diagnostic system select the vehicle configuration main menu>select configure existing modules menu and program the satellite radio module
U3000-87	Control Module - missing message	The satellite radio module has not received the configuration file Master module not transmitting configuration file	Using the manufacturer approved diagnostic system check that the satellite radio module is configured correctly Check that the configuration file is being transmitted by the master module Using the manufacturer approved diagnostic system, complete a MOST network integrity test
U3000-98	Control Module - component or system over temperature	Satellite radio module cooling vents obstructed Wiring harness fault Internal electronic failure	Check for possible causes of the satellite radio module overheating. Check that the ventilation is not obstructed Check for short circuit related DTCs. Refer to the electrical circuit diagrams and check ground circuit for high resistance. Check antenna circuit for short to power or ground. Repair wiring harness as required. Clear DTC and retest Check for internal electronic failure related DTCs If fault persists, check and install a new satellite radio 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/component
U3003-62	Battery Voltage - signal compare failure	Signal compare failure Satellite radio module voltage differs more than ±2V compared to rear junction box voltage	Refer to relevant section of workshop manual and battery care manual. Check battery state of charge and starting/charging system performance. Check power supply circuit from rear junction box to satellite radio module Refer to electrical circuit diagrams and check the power and ground supply circuits to the module. Repair wiring harness as required. Clear DTC and retest
