LCM Mitsubishi Electric – MCU NEC V850 70F3548 (Porsche)

LCM Mitsubishi Electric – MCU NEC V850 uPD70F3548 (Porsche)

Professional cloning service dedicated to Mitsubishi Electric (MEC) LCM (Light Control Module) electronic units, used for managing front LED lighting systems on Porsche vehicles.

Modules of the 7PP941572 family, also identified by the designation LED LEIMO MAX + DRL, manage electronic functions of the front headlights, according to the configuration of the lighting system installed on the vehicle.

Cloning allows the necessary data to be transferred from the original module to a technically compatible replacement unit, preserving, where possible, the configuration information required for the system to function.

AVAILABLE OPERATIONS

Cloning
Required material: original LCM module and target LCM module

Transfer of the necessary data from the original unit to a compatible replacement module.

The service includes identification of the units, reading of the available data from the original module, programming of the target unit, and verification of the operations performed.

The procedure involves the data necessary for module configuration and should not be considered a simple replacement or programming of the NEC V850 microcontroller.

Cloning is subject to the readability of the original data and the hardware compatibility of the two units.

SERVICE MODALITIES

Complete processing at Tsec Engineering

The service is carried out exclusively at our lab and requires the physical shipment of both units:

• Original module: unit previously installed on the vehicle, containing the data to be transferred.
• Target module: working and technically compatible replacement unit, on which cloning will be performed.

Both modules must be clearly identified as original and target.

Shipping the units to Tsec Engineering is the customer’s responsibility and at their expense. The shipping costs calculated at checkout refer exclusively to the return of the processed material.

Online file processing is not available.

COMPATIBILITY AND REQUIREMENTS

The service is dedicated to Mitsubishi Electric LCM modules of the supported family, equipped with NEC V850 uPD70F3548 microcontroller.

Main identification references:

• Porsche / VAG code: 7PP941572BB.
• Mitsubishi Electric code: W003T25076.
• Version shown on label: 7PP941572B H09.
• System: LED LEIMO MAX + DRL.

To perform cloning, the following is required:

• The original module contains intact and readable data.
• The target module is working and technically compatible.
• Both units are available for the service.

The presence of the same microcontroller alone does not guarantee compatibility between modules.

Any alternative codes or different revisions must be verified before purchase.

IMPORTANT INFORMATION

The service exclusively includes the cloning of data between compatible modules.

Does not include repair of hardware faults in the original or replacement module.

Cloning does not resolve malfunctions caused by damaged electronic components, water infiltration, power supply issues, faulty wiring, or LED headlight failures.

If data is unreadable, memory is damaged, or there is hardware incompatibility, cloning may not be possible.

Depending on the vehicle and the installed lighting system, further diagnostic checks or configuration procedures may be required after installation.

Correct operation of the lighting system must be verified on the vehicle after installation.

Any ECU shown in the images is for illustrative purposes and is not included with the product.
