A question for all you experts. Have a P38 Diesel 1996, air suspension stopped working and there are no red indicator lights in the cab (all off). Normally OK with fixing air suspension, but can't find any information on this fault. No faults shown from EAS Unlock, checked all fuses etc. Pump runs OK via EAS Unlock. Can read and write heights etc but will not raise of lower. Pumped it up manually, stayed up for a while then the rear suspension went to the stops for no apparent reason. Now using it with the relay removed, no leaks. Any thoughts please?

Hello and welcome
have a look in the tech archive top left of the range rover home page in there you will find a post by the late Wammers on eas in there is a check list that would be the first step

Left footwell connectors C104 & C204 might be corroded, although EAS diagnostic connects through these as well, so might not be that. The height switch ground is separate and would have the same effect. If the height switch ground is intermittent it could trigger strange operation.

Check the footwell connectors just in case.

+1 on connectors in footwell behind kick panel.

What happens is you replace the delay relay eith a standard one (note this will stop EAS diag working).

Thank you very much for all your help with this.
brianp38dse Have downloaded the eas system information doc and had a look at the technical archive sadly don't have testbook and only one mention of red height indicator lights and only to state when they should illuminate 'Engine Running Wake-UP'
pwood999 Checked Left footwell connectors C104 & C204 they are OK and not corroded. Next job then to check the ground on the height switch.
Grrrrrr Have checked the delay relay, which is ok and done the test pin 1 to pin 5 on the OBD2 plug. Will try standard one though to see.
Thanks again, will report any developments.
