COMPATIBILITY
Suitable for applicable:
• Land Rover Discovery 4 L319
• Middle / second-row heated seat applications
• Left-hand / N/S middle-row seat
• Vehicles equipped with the corresponding rear heated-seat system
• Seats using AH22-600D76-BA
Discovery 4 seating equipment varies according to model year, trim level, market and optional equipment.
Compatibility should therefore be confirmed primarily by matching the original heating element number:
AH22-600D76-BA
Engine size does not determine compatibility with this component.
TECHNICAL INFORMATION
The seat heating element is installed underneath the seat upholstery and forms part of the heated-seat system.
When the heated-seat function is activated, electrical current passes through the heating element, producing controlled heat that is transferred through the seat padding and upholstery.
The system works together with components including:
• Seat heating controls
• Seat wiring harness
• Heater control electronics
• Electrical power supply
• Seat heating element
• Temperature monitoring/control components where fitted
HEATED SEAT SYSTEM INFORMATION
A seat heating system generally contains separate components within the seat assembly.
If only one section of a heated seat stops warming, the fault can be caused by an open circuit or damage within the corresponding heater element rather than the main vehicle heating controls.
Because Discovery 4 seat specifications differ, the electrical connector and element design should be compared carefully before installation.
COMMON SYMPTOMS / REASONS FOR REPLACEMENT
• Middle-row heated seat not warming
• Seat heating works intermittently
• One section of the seat remains cold
• Heating switches on but stops shortly afterwards
• Open circuit within the heating element
• Broken or damaged element wiring
• Damaged electrical connector
• Replacement required during seat upholstery repair
IMPORTANT DIAGNOSTIC INFORMATION
A non-working heated seat does not automatically mean that the heating element has failed.
Before replacement, check:
• Heating element continuity
• Electrical connector
• Seat wiring harness
• Power and earth supply
• Heated-seat controls
• Heater control module where applicable
• Wiring for damage or trapped sections
• Relevant diagnostic fault codes
Testing continuity/resistance across the element can help identify an internal break.
INSTALLATION
Installation requires removal or partial removal of the seat upholstery to access the heating element.
Care must be taken not to:
• Damage the replacement heating element
• Trap or pinch the wiring
• Damage the seat upholstery
• Incorrectly route the electrical wiring
• Damage seat mounting or restraint-related components
Professional installation is recommended.
PROGRAMMING / CODING
The heating element itself does not normally require programming or coding.
Once correctly installed and connected, it operates as part of the existing heated-seat system.
Any existing electrical or control-system faults should be diagnosed separately.
IMPORTANT COMPATIBILITY NOTE
Please match the number on your original heating element:
AH22-600D76-BA
Also compare:
• Electrical connector
• Wiring length and routing
• Element shape and dimensions
• Mounting/attachment arrangement
• Exact seat position
• Vehicle heated-seat specification
Do not purchase solely because your vehicle is a Discovery 4.
Different seating positions and equipment specifications can use different heating elements.
The safest replacement is an exact AH22-600D76-BA match.
