    2001 Range Rover P38 ECU Repair

    ECU needs attention. Can anyone recommend where to send the unit for repair? Currently located in northern California. Thank you.

    Are you talking about the BECM or one of the individual ECU's?

    Re: 2001 Range Rover P38 ECU Repair

    If you are talking about Engine Control Unit (ECU), the computer that controls engine, it can not be simply swapped. The BeCM (body computer that controls central lock, power windows and a bunch of other stuff) has to be programmed to send the correct "mobilization code" to the ECU. The programming can be easily done using Rover-specific tools. Swapping a used replacement unit won't work (truck won't start), unless the programming to pair ECU and BeCM is done.

    Swapping BeCM opens another can of worms, because BeCM is matched with the Remotes/Key Fobs. The easiest way is to swap a used ECU and have someone with rover-specific gear do the requisite programming. Otherwise you are swapping ECU, Instrument Cluster, BeCM and lock set. Which is not a lot of work, but will set you back something to the tune of $300. The problem with swapping the whole caboodle is that VIN programmed into the BeCM no longer matches the truck, which creates problem when ordering replacement key fobs.

    Back everything (metaphorically) up a little bit first aswell....

    What's actually going on with the vehicle - what's working/not working etc, and how has it been diagnosed that the ECU needs repair (and which one as the others have mentioned).

    It *could* be that something external to the ECU is causing the problem and the ECU itself is actually fine - but we can't help diagnose it/confirm diagnosis if we have no information to go on!
