Land Rover Range Rover (L405) Sport (L494) PHEV P400e BECM Replacement Chip TC264 New Ready to Install

Description

The TC264 Chip must be replaced when BECM, the battery control module, is corrupted. Unfortunately, there is no solution which prevents replacing the BECM or the CPU, however this solution allows good electronic repairers to solve a very big problem!

After installing the CPU, you can test the battery in OBD diagnostic using our platform. Make sure to check for error codes with a diagnostic!
Once installed on car, you need to program the BECM with a Land Rover diagnostic tool (Topix, SX or Pluto all can work).

Note this service solves only the software problem on the BECM. If the BECM or battery have hardware faults as well, these are unrelated for the scope of this service.
As CPU needs to be soldered, it requires some skill to do it without damaging the module or the chip. For this reason, we do are not able to offer refunds on CPUs once package has been opened.

If chip has problems, you will have P0AA0-66 as a permanent code. 

Another possible problem on this battery which is entirely hardware is the current sensor data being unreliable, which is a problem with the safety box (SBOX) as mentioned here:

Supported part numbers:
P400e BECMs (L494/L405 only)
P300e BECMs (L494/L405 only)

Chip is provided with VIN from our test car. This is because chip must be tested for a long time to make sure there will not be issues shortly after install. VIN does not have to match your vehicle to make BECM work.

Other modules from platforms such as L551, L560, L550, L663 are using the same Samsung BECM system and have the same faults, however we do not yet have confirmed tested solution (test platform is the same). 
If you want to apply to test it, contact us! You may need SXTOOL in this case.
