is it the BeCM

HI to you all. can you help

My range rover 4.0 SE has lost its air suspension and braks plus a lot more. All the warning lights are on for the ABS/SRS/traction control
and the message cente got the warnings of EAS fault/ ABS fault/ traction control fault/ traction failure/ alternator fault/ slow 35 mph max. and the air con is not working or the f/and/r window heater not working. I have looked at the BecM and all looks ok. THe suspenson is on the deck and i have to pump the braks for them to work.

all the best

Probably not Becm,sounds more like a power supply fault with all the ecu's throwing low voltage faults back up to the instrument pack.Have a good look around the engine compartment fuse box,make sure battery voltage is available, (13-14.4v engine running) at the fuses that are live with engine running.Other than general checks,it sounds like you need to get the car to a LR specialist to sort it.Trouble is,some of the ecu's need reseting on a diagnostic computer when they store faults.( srs,eas etc.)

Thanks for the reply . I Have had a good look around the engine compartment and fuse box and it all looks ok to me But what do i know i will keep looking


all the very best

Hi to you all. I have had a good look at the fuse box and all the fuses are at 13v . The fuses on the BECM are 13v all but one F6 and that had a voltage of 11v with engine running looking at the circuit diagram there is a relay R10 could this be were the fult is. If this is the fult how do i fix it

all the very best
