DTC Index

WARNING: This page is about a different car, the 2006 Land Rover Range Rover Sport. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If the control module 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 Program is in operation, prior to the installation of a new module.

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 additional information read by the manufacturer approved diagnostic system).

NOTE: When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places, and with an up-to-date 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: Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.

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.

Refer to the electrical guides. Refer to the warranty policy and procedures manual if a module is suspect. Check and install a new front touch screen display as required, refer to the new module/component installation note at the top of the DTC Index
B1A8911	Satellite Antenna	NOTE: Navigation diagnostics Self Check code 80-3B GPS antenna circuit - short to ground GPS antenna failure Navigation module failure	Check for correct installation of GPS antenna. Refer to the electrical circuit diagrams and check GPS antenna circuit for short to ground. Check GPS antenna, install a new antenna as required. Check and install a new navigation module as required, refer to the new module/component installation note at the top of the DTC Index
B1A8913	Satellite Antenna	NOTE: Navigation diagnostics Self Check code 80-3A Global positioning system (GPS) antenna high resistance The co-axial connector can also set this code GPS antenna failure	Check for correct installation of GPS antenna. Refer to the electrical circuit diagrams and check GPS antenna circuit for open circuit. Check GPS antenna, install a new antenna as required
B1B0049	Sub-Module 'A'	NOTE: Navigation diagnostics Self Check code 80-11, 58-02, 08-42, 08-43 Navigation module internal failure	Check for excessive temperature and for the correct installation of the navigation module. Install a new navigation module as required, refer to the new module/component installation note at the top of this DTC Index
B1D6249	Sub-Module 'B'	NOTE: Navigation diagnostics Self Check code 32-4B Vehicle information and communication system (VICS) module internal electrical failure	Check the power and ground circuits to the module. Refer to the electrical guides. Check and install a new VICS module as required, refer to the new module/component installation note at the top of the DTC Index. Refer to the warranty policy and procedures manual if a module is suspect.
B1D6287	Sub-Module 'B'	NOTE: Navigation diagnostics Self Check code 32-30 Vehicle information and communication system (VICS) module circuit - short to ground VICS module circuit - short to power VICS module circuit - high resistance VICS module disconnected VICS module failure	Refer to the electrical circuit diagrams and check VICS module circuits for short to ground, power, open circuit. Check and install a new VICS module as required, refer to the new module/component installation note at the top of the DTC Index. Configure the system using the approved diagnostic system.
U1A0087	Medium Speed CAN Communication Bus	NOTE: Navigation diagnostics Self Check code 01-50, 01-51, 30-28, 30-D2 NOTE: 'NAVIGATION NOT INSTALLED' message is displayed Navigation module disconnected CAN fault between NAV module and TSD private CAN circuit Private CAN circuit - short to ground, power, open circuit	Check the system connections at the display and the navigation module. Refer to the electrical circuit diagrams and check CAN private network for short, open circuit. Carry out CAN network integrity tests using the manufacturer approved diagnostic system. Refer to the Network Communications section of the workshop manual.
U1A0131	Communication Link	NOTE: 'NO NAVIGATION AVAILABLE' message is displayed Navigation module - touch screen display (TSD), gigabit video interface (GVIF) fault GVIF disconnected GVIF - short to ground, power, open circuit	Check for correct connection of GVIF circuit connectors. Refer to the electrical circuit diagrams and check the multi-media module GVIF circuits for short to ground, power, open circuit
U200531	Vehicle Speed	Vehicle speed signal circuit between ABS and navigation system module - short, open circuit	Check 'SPD PULSE COUNT' in navigation diagnostics, vehicle signals screen. If count remains at zero, refer to the electrical guides and check vehicle speed signal circuit between the ABS module and navigation system module for short to ground, power or open circuit.
U300068	Control Module	NOTE: Navigation diagnostics Self Check code 30-76 Touch screen display (TSD) MOST fibre optic transceiver, over-temperature (greater than 85°C) MOST transceiver over-temperature	An over-temperature message is displayed on the TSD before the information and entertainment system shuts down. Once the temperature is reduced the system will resume normal operation. If the system does not resume normal operation, check for DTCs indicating an information and entertainment fault. Refer to the electrical guides and check the power and ground circuits to the component. Check the MOST circuit. Carry out the general MOST test. Refer to the Network Communications section of the workshop manual and in the approved diagnostic system. Refer to the warranty policy and procedures manual if a module is suspect.
