TECHNICAL INFORMATION

The seat heater control module forms part of the vehicle’s electrically heated seat system.

Its primary function is to regulate operation of the heating elements installed within the seat cushion and backrest.

The module works together with:

• Seat heating elements

• Vehicle climate / heating controls

• Seat wiring harness

• Temperature monitoring components

• Vehicle electrical network

• Relevant control modules

When seat heating is requested, the control system manages electrical power supplied to the heating elements to provide the selected heating level.

HEATED SEAT SYSTEM INFORMATION

Discovery 4 vehicles were available with different seat specifications and equipment levels.

Depending on specification, the vehicle may have:

• Heated front seats

• Different seat upholstery specifications

• Manual or electrically adjustable seats

• Memory seat functions

• Different heating modules and wiring configurations

For this reason, the module number should always be checked against the original component.

COMMON SYMPTOMS / REASONS FOR REPLACEMENT

• Heated seat completely inoperative

• Seat heating works intermittently

• Seat does not reach the selected temperature

• Heating switches on and then stops

• One heated seat works while the other does not

• Diagnostic communication fault relating to seat heating

• Internal control module failure

• Electrical or connector damage

• Replacement required during heated-seat repair

IMPORTANT DIAGNOSTIC INFORMATION

A non-working heated seat does not automatically indicate a failed control module.

Before replacement, check:

• Seat heating element continuity

• Seat wiring harness

• Electrical connectors underneath the seat

• Vehicle fuses

• Power and earth supply

• Heating controls

• Temperature sensor where applicable

• Diagnostic fault codes

Broken heating elements within the seat cushion or backrest can produce symptoms similar to a failed control module.

INSTALLATION

The module is associated with the front seat heating system and may be mounted underneath or within the seat assembly depending on vehicle configuration.

Before working on the front seat electrical system, disconnect the vehicle battery according to the correct Land Rover workshop procedure.

Take particular care around the seat wiring because the front seat assembly also contains SRS / airbag-related components.

Professional installation and diagnostic checking are recommended.

PROGRAMMING / CODING

Depending on the vehicle specification and replacement module, diagnostic configuration may be required after installation.

Where communication or configuration faults remain after replacement, the vehicle should be checked using suitable Land Rover/JLR diagnostic equipment.
