EAS problem 99 P38

stu306 · Nov 15, 2012

Hi
EAS problem 99 P38
EAS was fine till about 9 months ago, had raised suspension to maximum with engine running as was topping up
the gearbox oil. In the process the front o/s airbag blew and car dropped. Turned off engine at this point.
Replaced both front airbags as back had already been done.
Once done started and no EAS fault, but checked anyway with Storey's software
Error00
But all worked as should do, up down, no dropping on any corner overnight, leveled within a few seconds of starting and has done till this week.
Been doing 100 odd miles a day, on Tuesday EAS Fault on route, followed by bump stops and 35 miles max.
Hobbled to destination and plugged in laptop. Unlocked EAS. All well again. Checked for errors.
Error11
Drove for a couple of more days everything working as should do, then tonight on the way home. EAS fault.
Not on Bump Stops yet. Checked out the errors.
Error22
Help, don't know where to start to diag this. Surely there cann't be that many faults and the system to work
for 9 Months. The 2 in error11 refer to the main pressure switch and the rear sensor.
Anyone any idea's
Thanks
Stu

First thing - Never work under an unsupported vehicle at any time....you have been very lucky!!

Second thing - Error00 and Error22 are showing that you don't have good comms and as such the fault list is spurious....and is not accurate....

Datatek and Wammers are the EAS Gurus on here, they'll be along no doubt to help diagnose...

My thoughts from Error11 is a Height Sensor Issue

Only number 2 readout is genuine other two are gibberish with no good idle on system. For pressure sensor fault try cleaning plugs to valve block and driver pack. Other fault R/L signal incorrect check plug on sensor is clean and making good contact. Vehicle has moved means nothing and can be ignored.

As Wammers said, only screen number 2 means anything, the other 2 you have no comms.
RL signal incorrect is connector corroded, or full of water or the sensor is knackered.
Again as Wammers said part the connectors in the EAS box and re make few times especially the ones under the valve block. Do NOT use WD40 on them, use contact cleaner if you have it.

Update

Unplugged and Contact Cleaned everything as instructed. Was using my laptop with USB to serial adaptor, switched to an old pc with serial onboard, connected up with FF replies and voila no faults.

Thanks Guys

Hi All need help i have a P38 EAS system seems to be doing auto leveling when engine is powered on or when at road traffic queues ?

When engine is started that is normal if car is parked for any length of time on uneven ground.
When vehicle speed goes lower than 1 mph front valves open to equalise pressure across axle. If there is a mismatch in pressure left to right the vehicle will drop then rise to selected height. Suggest you check levels across front axle.
