2009 Land Rover LR2 HSE 3.2L (N) 6-spd (AWF21)
No Crank

2009 LAND ROVER LR2. This call came to us from another shop that we do programming for. They replaced the abs module and when doing so I guess the battery had went dead . Since charging the battery up the vehicle will not start . They have looked into the issue and I guess when the battery goes dead it can put the vehicle into a crash mode . So they have asked if I can do a crash mode reset . Has anyone done this before ? Is it a flash update or a simple scan tool function ? Thank you for taking the time to read my post

MMY? Jeff, it depends on the vehicle make model and year. Maybe I'm missing something, but I do not see any accompanying vehicle info. E.G, on a 2019 Volt, there is Config/Reset function in EBCM and in HPCM2. If GDS 2 is used to disable the high voltage, the system opens the contactors and sets a crash event status that requires accessing and resetting in HPCM 2, Config/Reset and Contactor…

Thanks Eric. Jeff updated it. I'm no LR tech, so I'm out other than expecting that the reset is likely listed in a menu in one of the modules.

I don’t believe this vehicle has a crash reset like a BMW or Mercedes has. However there should be a “Vehicle Reset“ option. Not sure what scan tools you have, but I would think this could be done a Launch or and Autel. Snap-On maybe.

You need to use SDD factory software. Go to body module and reset

Hi Jeff, its a common problem and the procedure is on the Autologic if you have one, Go To Land Rover>Freelander>Freelander/LR…>Body>Body Control Module>Special Functions>Crash Status Reset>Continue and follow the prompts (key on key off cyles) and clear codes

Charge battery on its own , retry once the voltage stabilizes

If you don't have a scan tool with the reset function, I wonder if a battery cable reset would do the trick? I suppose it may leave you in the same boat since a dead battery is what caused all of this in the first place. I don't think you'd hurt anything trying it though but I'm certainly no authority on these vehicles. In any case, hope this helps.

Too funny that I would read this the day after having the exact same year vehicle and problems. Autologic was indeed necessary for me to bring the vehicle back. Performing the crash reset was step one on mine. Secondly I had codes that were also for the Immobilizer, which as I found out were due to a weak key. Leaving the key in the on position for awhile was enough to bring it back to life …

Its can be recovered with SDD majority of the time. Which modules can you still talk too?
