Satellite Radio Control Module (SRCM)

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.

NOTE:

Guided Diagnostics must be followed and the repair advised by the process completed. Failure to do so may result in the rejection of any warranty claim made.
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures information, or determine if any prior approval programme is in operation, prior to the installation of a new module/component.
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).
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.
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.
Check JLR claims submission system for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific customer complaint and carry out the recommendations as required.

The article below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Satellite Radio Control Module (SRCM). For additional diagnosis and testing information, refer to the relevant Diagnosis and Testing article in the repair information.

DTC	DESCRIPTION	POSSIBLE CAUSES	ACTION
B1A89-01	Satellite Antenna - General electrical failure	Satellite radio antenna circuit short circuit to ground, short circuit to power, open circuit, high resistance Satellite radio antenna amplifier internal failure Satellite radio control module internal failure	Refer to the appropriate system wiring diagrams and check the satellite radio antenna circuit for short circuit to ground, short circuit to power, open circuit, high resistance Using the manufacturer approved diagnostic system, clear the DTCs and retest. If the fault persists, install a new satellite radio antenna amplifier Using the manufacturer approved diagnostic system, clear the DTCs and retest. If the fault persists, install a new satellite radio control module
U3000-4A	Control Module - Incorrect component installed	Car configuration file mismatch	Using the manufacturer approved diagnostic system, check and up-date the car configuration file as necessary. Clear the diagnostic trouble code and re-test
U3000-55	Control Module - Not configured	Satellite radio control module not configured	Using the manufacturer approved diagnostic system, re-configure the satellite radio control module with the latest level software
U3000-87	Control Module - Missing message	Satellite radio control module configuration incomplete/corrupted	Using the manufacturer approved diagnostic system, re-configure the satellite radio control module with the latest level software
U3000-98	Control Module - Component or system over temperature	Satellite radio control module cooling vents obstructed Satellite radio control module internal failure	Check that the satellite radio control module cooling vents/air circulation are not obstructed. Cool the vehicle interior down by ensuring it is in the shade and have the A/C on cool. Using the manufacturer approved diagnostic system, clear the DTCs and retest Using the manufacturer approved diagnostic system, clear the DTCs and retest. If the fault persists, install a new satellite radio control module
