Alternative Format: AH4215K602BC

OE / Cross Reference: LR012398

Additional Reference: 5E0760177

Manufacturer: Lear Corporation / Land Rover OE

Part Type: RF Receiver / Radio Frequency Receiver Control Module

System: Passive Entry / Remote Keyless Entry / Vehicle RF System

Donor Vehicle: 2010 Land Rover Discovery 4 L319

Condition: Genuine Used

Compatibility

Confirmed applications include:

• Land Rover Discovery 4 L319 / LR4

• 2010 Discovery 4

• 2.7 TDV6 – 276DT applications

• 3.0 TDV6 / SDV6 – 306DT applications

• Other Discovery 4 model years using the identical AH42-15K602-BC receiver

A documented 2010 Discovery 4 2.7 TDV6 donor pairs LR012398 with AH4215K602BC. (OVOKO)

Used-parts fitment records also document AH42-15K602-BC on Discovery 4 2.7 TDV6 and 3.0 TDV6/SDV6 applications. (BreakerYard)

Additional Applications

The same AH42-15K602-BC receiver is also documented on selected:

• Range Rover Sport L320

• Range Rover L322

• Range Rover Sport L494

• Range Rover L405

• Range Rover Evoque L538

• Discovery Sport L550

• Other Jaguar Land Rover applications using the identical receiver specification

These additional applications should always be confirmed by matching the complete AH42-15K602-BC number, connector arrangement and vehicle equipment.

Technical Information

Land Rover’s official type-approval documentation identifies AH42-15K602-BC as a Lear Corporation RF Receiver. (TOPIx)

Depending on vehicle specification, the receiver is associated with functions including:

• Passive entry

• Passive start

• Remote keyless entry

• Key-fob RF signal reception

• Vehicle security / access system

• Tyre Pressure Monitoring System integration

This unit receives RF signals and communicates the relevant information to the vehicle’s electronic systems.

Important – This Is Not an Audio Amplifier

Despite some used-parts listings describing AH42-15K602-BC as a “radio receiver” or “antenna amplifier”, this should not be confused with the vehicle’s audio amplifier.

Land Rover/Lear homologation documentation describes the AH42-15K602 family as an RF receiver used for passive entry, keyless functions and TPMS-related systems. (TOPIx)

Vehicle RF / Keyless System Information

The receiver works as part of a wider electronic system that can include:

• Remote key fob

• Passive keyless entry system

• Passive start system

• Vehicle security electronics

• RF antennas

• Body control electronics

• TPMS components depending on specification

• Associated wiring and connectors

A keyless-entry or remote-control problem therefore does not automatically mean this receiver has failed.

Common Symptoms / Reasons for Replacement

• Remote key not responding correctly

• Reduced or intermittent remote operation

• Passive entry malfunction

• Keyless entry fault

• Passive start communication problems

• RF receiver communication fault

• Diagnostic fault relating to receiver module

• Internal electronic failure

• Water / moisture damage

• Damaged electrical connector

• Original receiver missing

Important Diagnostic Information

Before replacing the receiver, check:

• Key-fob battery

• Spare key operation

• Vehicle battery condition

• Relevant fuses

• RF receiver wiring

• Electrical connectors

• Keyless-entry antennas

• Vehicle diagnostic fault codes

• TPMS system where relevant

Using suitable Land Rover-compatible diagnostic equipment is recommended before replacing electronic control components.

Installation

Install the replacement receiver in the same factory position as the original unit.

During installation:

• Disconnect connectors carefully

• Check terminals for corrosion or damage

• Compare the complete engineering number

• Ensure connectors are fully seated

• Secure the module correctly

• Keep wiring in its original routing

Programming / Coding

Programming requirements can depend on the vehicle and the repair being performed.

For a like-for-like AH42-15K602-BC replacement, compatibility should be confirmed before installation, and the keyless/security system should be checked with suitable diagnostic equipment afterwards if operation is not restored.

Do not assume that replacing this receiver alone will resolve key programming or immobiliser-related problems.

Important Compatibility Note

⚠️ Please match the complete part number before purchasing.

Check:

• AH42-15K602-BC

• AH4215K602BC

• LR012398 where applicable

• Electrical connectors

• Module housing

• Vehicle keyless/security specification

• Listing photographs

The AH42-15K602 family has numerous revisions including AB, BA, BB, BC, BD, BE, BF, BG and BH, documented by Land Rover/Lear. (TOPIx)

Therefore, matching the complete suffix is strongly recommended rather than purchasing solely by model and year.

Condition

Genuine used Land Rover / Lear electronic module.

May show normal signs of previous use, removal and storage, including light marks or cosmetic wear to the housing.

Please inspect all listing photographs carefully for the exact part number, connector configuration and overall condition.
