Another EAS Troubleshooting request

All,

Have been through the forum and found some good blogs on troubleshooting Air Suspension.

Mine worked great on my 2003 HSE RR. I have 39,000 on it and it just frooze in the neutral position. Just the Inactive Suspension message on the display. I was hoping someone has gone through the diagnosis process and can shed some light. What I have done:

1. Replaced the pads on the front. Done dozens of ABS so no issues, ABS works fine (tested on ice) and the suspension worked after for a period of 2 weeks. The only odd thing I found in the ABS was there was only 1 sensor on the front brakes. Is that normal? Even so, the Suspension worked after installation. Note this because I hear ABS and EAS are closely tied together in Rovers.

2. Been through some deep snow the day before the failure. Suspension still worked that morning but failed in the afternoon.

3. So far, checked the 50 Amp fuse in the rear panel, will check # 57 in the front but suspect no issues there.

Is there a way test the compressor directly from the battery? I've also read about a few Sensors, would like to look at them as well. Any one have any testing advice? Thanks all, I appreceiate anything you can provide on my first ROver Electronics hunt.

New Rover Man, Bob

Bob,

Good luck with the troubleshooting. I unfortunately am also having intermittent issues with my 2004 and the dreaded "air suspension inactive" message.

I believe that my problem relates to having moisture in the system, as my problem will only rear it's ugly head when I park my Rover outside in sub-zero weather. I bought a product called EAS Activate which will clear the "inactive message" and also provide some rudimenatry info as to what might be the cause of your problems. Short of the EAS activate, you will need to take your rover to the dealer to get the system active again and they may/may not be able to provide a definitive diagnosis.

Seems that there have been a number of fixes reported including a software update, replacing the valve block/compressor, and the various sensors.

Bob,
Sometimes it helps tremendously to have access to the stored EAS Fault codes. Although other times, the fault codes can be a bit misleading. Either way, it helps to have a tool where you can pull the codes and reset the system whenever you need to.
The symtpoms that you describe could be several innocent things like moisture or cold weather leaks. We will not know unitl you have the codes read. I sell a tool called the "EAS Activate" it is designed to clear and read the stored EAS fault codes;

Hi R.Story and Voper.

I do have an OBD reader and found two codes one High Fuel level sensor ( P0463 ) and the other Manufacturer specific or PowerTrain(P1709). The later appears to be the Problem. Any thoughts out there before I have to bring it to the Sharks? :twisted:

R, nice tool you have there, I may take you up on the offer. You take Credit cards? Let me know.

Bob,
A standard OBDII code reader will not help diagnose the EAS. The EAS Activate tool is designed to specifically communicate with the EAS. The only way to talk with the Range Rover EAS, is to purchase a specialized diagnostic tool.
All orders are processed through mt website. All payments are processed through Paypal. Paypal accepts all major credit cards. Payment can be completed without joinning Paypal.

Let me know if you have any more questions.
