Manual EAS Re-inflation

My EAS is currently in hard-fault mode, and I'm due for a wonderful 15-mile journey at 15mph tomorrow morning in rush-hour traffic to the local diagnostic guy.

I read that it's possible to manually recharge the EAS system even under a hard-fault condition by shorting across the EAS Relay 20 (Pins 30-87) which will manually run the compressor and should recharge the system. This assumes the system is airtight. Even if it doesn't recharge fully, you can get enough air to get off the bumps. Only problem is that it bypasses the over-pressure cut-out so you need to manually switch off before that happens.

Anyone got any idea how long it might take the compressor to fill the tank and four bottomed-out airbags?

til it goes up a bit?

Being a Rangie, it's not that simple. From what I read, (rangerovers.net) it seems that you have to switch the engine off, and it's only when you restart the engine, the tank will charge the air springs, but not before!

If you were to go down the 'manual' route you would need to get power to the compressor to get it to run, get power to the solenoid to open up the valve to the Air reciever (Tank) to allow the reciever to be filled.

Usually the tank is filled in 5-7mins from totally empty (But DONT take my word for it as it is all dependant on efficency of pump, leaks, tempurature etc)

After you have done that you need to close the Valve and shut down the pump.

Then to get the air from the Reciever to the springs, you need to get power to the 4 spring solenoids to open the valves, then get power to the solenoid that controls the valve for the air from the reciever to get to the valve block this will allow the air from the reciever to get into the springs.

Once the springs are inflated, you need to close the spring valves and the receiver valve.

Now you need to get power to the Exhaust Solenoid to open the exhaust valve to dump the residual pressure in the valve block to atmosphere.

Simple!! But I wouldn't suggest you try this....

Instead, try looking into tapping into the Spring pipes and tee-ing off to a set of Schreider type valves and using a compressor to fill the springs that way....do a google on the MARS system (I think that is what it is called) basically it just bypasses the valve block to allow you to manually pump the springs up.

Have fun
