Although its a brand new battery are you sure that it is fully charged?

 

Even if the battery was sold new it doesn't mean it is a good battery.

Battery terminals might not be making a good solid connection, which is the first think I would check. The positive and negative cables are the least expensive items that could cause the problem.

I would suspect the alternator as a possible problem although the new battery should have lasted longer even without the alternator charging properly.

 

Well every time a battery is tested it losses charge due to the test and this is signs of drainage. You must take the car to a specialist.

There are stories of a bad batch of earth straps that look good at the terminals but are corroded under the insulation. It might be worth fitting an extra earth strap direct from the negative terminal of the battery to one of the starter motor mounting bolts. If that improves things then a new standard earth strap wouldn't hurt.

 

When the battery went dead in my LR2, it's really low when the key fob won't release, I put it on the charger to get enough juice to release the key. Mine didn't want to start either after a new battery.

I believe I installed a fresh battery in the key fob after cleaning it and then it started with no problems.

 

There have been big issues with LR2s that the battery drains down slowly on. As voltage gets low, some modules are not able to communicate, which can cause them to do strange things.

What ends up happening is the vehicle will enter Crash Mode due to the lack of voltage, and different modules getting 'confused'. This is not an issue when all power is removed, such as disconnecting the battery, as there is no communication at all then.

Crash Mode sometimes requires a reset with dealer level diagnostic equipment, also sometimes resets itself, and there is a procedure(which I have never had actually work) that involves ignition cycles and remote lock/unlock cycles.

Crash Mode is set by the Body Control Module, and stored in the PCM. Sometimes you can get lucky and the BCM will 'unset' it, but it will still be stored in the PCM, and prevent engine cranking. In this case, clearing fault codes with even just a generic scanner will do the trick.

There is a software update to the BCM available to prevent this, however it is usually only preformed after it has been an issue.

Lastly, there have been several starter motor failures, but this should not coincide with a dead battery, but I would suggest making sure that the battery has actually failed, and was not replaced due to a separate no-crank issue.

 

My 2009 LR2 has just changed a new battery 2 months ago at dealer. Today, the car is not able to start, although there are all signs that the battery is working - dash board lights are all on. What is the problem?

 

Hello, I know its old Post but i was wondring if you ever get that fixed? I am having same issue with the same car

 

I had this happen to a 08 lr2. After buying a new battery, still same issue. Returned that and purchased a starter, still same issue. So I tested the continuity from the positive end by the starter to the battery post, no continuity. Took the clip off the circuit breaker on the positive post, and found that it actually had split causing no voltage. Had to replace the terminal end with a built in fuse. So idk if this will help all but after a while of trying to figure out the issue. It was in fact the positive battery cable.

 

I am having same issues. I replaced alternator and battery. Codes read Lost communication with starter/generator control module & Generator control circuit. I’m thinking it’s the connector to the alternator, which I assume is the voltage regulator? Any help would be much appreciated!

 

 

I have the same problem I have a Land Rover 08 LR2 it won’t start I change the battery I change the starter n nothing everything inside will turn on like radio lights but won’t turn the engine on any help this is my only vehicle to go to work

 

l am having the same issue With my 08 LR2. Replaced the battery and will be testing the Starter Relay next. Will update the post when I get it resolved.

 

Check the wiring on the starter again, and check the ground straps. It's easy to forget to hook up the little wire, but I think it's on top of the starter. Check the fuse for the starter solenoid. Do you hear anything from the starter, clunks or clicks? Or silence?

Any messages on the dash? Did you pull DTC codes with a scanner?

Try a computer reset:
Disconnect both battery cables.
Wait ten minutes
Touch battery cable ends together
Wait ten
Connect battery
Wait ten
Insert key fob (don't turn on)
Wait ten
Turn car systems on, but not the motor (with foot off brake, press and hold start button for a few seconds)
Wait ten
Start engine, drive around a bit
