Head-Up Display (HUD)

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 a control module or a component is at fault or may be at fault and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures information, or determine if any prior approval program 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 Jaguar Land Rover approved diagnostic equipment).
When performing voltage or resistance tests, always use a digital multimeter that has the resolution ability to view 3 decimal places. For example, on the 2 volts range can measure 1 mV or 2 K Ohm range can measure 1 Ohm. 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 complete the recommendations as required.

The article below lists all diagnostic trouble codes that could be set in the Head-Up Display (HUD). For additional diagnosis and testing information, refer to the relevant Diagnosis and Testing article in the repair information. For additional information, Refer to: INFORMATION AND MESSAGE CENTER

DTC	DESCRIPTION	POSSIBLE CAUSES	ACTION
U0055-87	Vehicle Communication Bus D - Missing Message	NOTE: Circuit reference - HS CAN H (CO) Circuit reference - HS CAN L (CO) Missing message from another control module through the high speed CAN bus (comfort)	Using the Jaguar Land Rover approved diagnostic equipment, check the snapshot data to determine the missing message source control module. Check the relevant control module for related DTCs and refer to the relevant DTC index
U0055-88	Vehicle Communication Bus D - Bus Off	NOTE: Circuit reference - HS CAN H (CO) - Circuit reference - HS CAN L (CO) - High speed CAN bus (comfort) circuit short circuit to ground, short circuit to power, open circuit, high resistance	Using the Jaguar Land Rover approved diagnostic equipment, perform a CAN network integrity test. Refer to the appropriate system wiring diagrams and check the high speed CAN bus (comfort) circuit for short circuit to ground, short circuit to power, open circuit, high resistance
U3000-07	Control Module - Mechanical Failures	Head-up display internal failure	Using the Jaguar Land Rover approved diagnostic equipment, clear the DTC and retest. If the fault persists, check and install a new head-up display as necessary
U3000-09	Control Module - Component Failures	Head-up display internal failure	Using the Jaguar Land Rover approved diagnostic equipment, clear the DTC and retest. If the fault persists, check and install a new head-up display as necessary
U3000-13	Control Module - Circuit Open	NOTE: Circuit reference - APIX2 TX - Circuit reference - APIX2 RX+ Circuit reference - APIX2 TX+ Circuit reference - APIX2 RX- Circuit reference - APIX2 SHIELD Instrument Cluster output circuit open circuit, high resistance	Refer to the appropriate system wiring diagrams and check the instrument cluster output circuit to the head-up display for open circuit, high resistance. Repair the wiring harness as necessary
U3000-49	Control Module - Internal Electronic Failure	Head-up display internal failure	Using the Jaguar Land Rover approved diagnostic equipment, clear the DTC and retest. If the fault persists, check and install a new head-up display as necessary
U3000-9A	Control Module - Component or System Operating Conditions	Head-up display temperature too high/low	NOTE: This DTC may log when the module is exposed to extreme operating temperatures. Such a condition should not require installation of a new module. The Head up display will resume operation when the internal temperature has normalized Allow the head-up display temperature to return to normal. Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest. If the fault persists, check and install a new head-up display as necessary
U0300-00	Internal Control Module Software Incompatibility - No Sub Type Information	Head up display is not configured correctly	Using the Jaguar Land Rover approved diagnostic equipment, re-configure the head-up display control module with the latest level software
U2300-64	Central Configuration - Signal Plausibility Failure	Car configuration file mismatch with vehicle specification	Using the Jaguar Land Rover approved diagnostic equipment, check and update the car configuration file as necessary. Clear the DTCs and retest
U2300-54	Central Configuration - Missing Calibration	Car configuration data not received	Using the Jaguar Land Rover approved diagnostic equipment, check and update the car configuration file as necessary. Clear the DTCs and retest
U2300-55	Central Configuration - Not Configured	Car configuration file mismatch with vehicle specification	Using the Jaguar Land Rover approved diagnostic equipment, check and update the car configuration file as necessary. Clear the DTCs and retest
U2300-56	Central Configuration - Invalid/Incomplete Configuration	Car configuration file mismatch with vehicle specification	Using the Jaguar Land Rover approved diagnostic equipment, check and update the car configuration file as necessary. Clear the DTCs and retest
B1A85-86	Ambient Light Sensor - Signal Invalid	Incorrect Rain/Light sensor installed	Install a new rain/light sensor as necessary
B1A85-96	Ambient Light Sensor - Component Internal Failure	Rain/light sensor failure	Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest. If the fault persists, install a new rain/light sensor as necessary
B100E-64	Video Input "A" - Signal Plausibility Failure	NOTE: Circuit reference - APIX2 RX+ Circuit reference - APIX2 RX- APIX2 Circuit, open circuit Instrument cluster Internal failure	Refer to the appropriate system wiring diagrams and check the APIX2 circuit for open circuit Using the Jaguar Land Rover approved diagnostic equipment, check the instrument cluster for related DTCs and refer to the relevant DTC index
