Restraints Control Module FLEXRAY Communication Table
For DTC s U0001-81, U0001-86 and U0001-87: Using the Jaguar Land Rover approved diagnostic equipment, check the snapshot data (0xD020) to determine the missing message source control module. Check the relevant control module for related DTC s and refer to the relevant DTC index. Using the Jaguar Land Rover approved diagnostic equipment, perform a FlexRay network integrity test. Refer to the electrical circuit diagrams and check the Vehicle communication bus F (FlexRay) between the relevant control module (for example as indicated by the snapshot data) and the restraints control module
