Land Rover Discovery Sport L550 Fuse Box FK72-14F041-AE - Used Original Parts

Diagnosis and Common Symptoms

As a technician, when a Discovery Sport presents with multiple, seemingly unrelated electrical faults, my attention often turns to the Central Junction Box (CJB), also known as the body control module. A failure in the FK72-14F041-AE unit can manifest in various ways, often intermittently at first. You may experience a parasitic battery drain that's difficult to trace, or a cluster of warning lights without a clear cause.

Common symptoms we see in the workshop include:

• Non-functional or erratic behaviour of wipers, indicators, or exterior/interior lighting.
• Central locking system failures or windows operating incorrectly.
• Dashboard warnings such as "General Electrical Failure" or specific system faults.
• Diagnostic scans may reveal communication loss fault codes, such as U0140 (Lost Communication With Body Control Module), or various B-codes (Body) indicating open or short circuits for components controlled by this module.
