DTC U3000-49: Control Module - Internal electronic failure: Action

NOTE: If this DTC is set and the airbag warning indicator is not illuminated, this indicates that the failure is related to the Inertia Measurement Unit (IMU) functionality. The IMU is set of sensors inside the restraints control module that measure the linear and angular motions of the vehicle

Refer to the electrical circuit diagrams and check the restraints control module power and ground circuits for open circuit, high resistance. Repair the wiring harness as necessary
Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest. If the fault persists, install a new restraints control module
