2013 Land Rover LR4 HSE Lux 5.0L (D) 6-spd (6HP28) — SALAK2D45DA678758
U3000-55
No Sound From Speakers

We have a difficult diagnostic session that we are failing on, I hope someone can give us a direction to move forward.

2013 Land Rover LR4

SALAK2D45DA678758

Amplifier part number: LR045325

Customer initial concern: touch screen inoperative/ broken.

Initial repair: replaced touch screen with factory new and programmed.

After repair found that most ring communication was down. Verified most ring circuit and found information regarding updating all modules on the network to restore communication. After updating software using Land rover SDD found communication to be restored but still no sound. Dtc stored in AAM (amplifier) is U3000-55. Researched and found this dtc resulting from missing programming in module. Using SDD attempted to reprogram amplifier, SDD said it has the most up to date software level but went ahead and tried again. Programming completed successfully, cleared codes. U3000-55 still present and no sound. Amplifier self test can be run and sounds are heard. Test completes successfully. Replaced amplifier with factory new and programmed using SDD. Programming completed successfully, still no sound, u3000-55 still present.

After talking with a Land Rover programming colleagues they determined from their sources that Land Rover SDD sometimes is unable to correctly interrogate the vehicle and choose the correct software for the module.

Obtained a list of amplifiers and corresponding software numbers but the one for this vehicle is not listed.

Need to some how obtain the correct software.

Has anyone got any relevant experience on a case like this?

Thanks for looking, I appreciate any help.

This DTC will occur once if a new module is installed. Clear the DTC, cycle the ignition state to off. Lock the vehicle (to ensure the infotainment system has reset). Unlock vehicle, cycle the ignition state to on. Retest the system. Straight from Topix. If it doesn’t work I would try a vehicle reset or a hard reset by touching the negative and positive battery cables together.

Thanks Oscar! The shop has performed this step several times now. Still no sound. I put this up on that Facebook page before I posted here, all I got was the sound of crickets.

Check for water ingress in the rear ¼ panels. I think the Range Rover is L/Rear and LR4 is R/Rear, then bypass the various MOST modules by holding the fiber optic cable together and see if you get sound. Ive actually got a prism that I use; Land Rover Part number: LR019014 Otherwise a hot melt glue stick and drill a hole down the middle to hold the fiber optic cables together. I've had similar…

Still no happiness on this. We did click on a button in SDD that showed “optionally fitted modules” for this chassis. Nav was in the list. We will liven up a Topix subscription to see if we can find where that module might be located.

Hi Paul, I dont log on as much as I should. I have a TOPIx subscription and can look up diagrams if you like. I'm not online as much as I should be so drop me a private mail, I'll post the diagrams here for everyone to see. …​.​za I'll need the VIN and specifics of what you are looking for. Rory.

Rory, Thanks for that offer, and we appreciate your offer. We have had another LR specialist that went over our procedure step by step and he put his blessing on our process. We are thinking the information that came out of the original module, in the suck and blow back process, somehow was not as expected. We have another module coming from the dealer. The killer is that when we test the…
