    I had a persistent error relating to high pressure in my EAS. The error always had a tendency to come on when the wife was in the vehicle but always at an inconvenient time and resulted in a hard fault. I tested the pressure sensor and checked for leaks and nothing was found to be faulty. It was driving me mad!!

    I started digging around on google to see what others did. The driver pack failure was a common cause where owners replaced the driver pack and the problem then disappeared.

    I looked at mine on the weekend and found that the rubber membrane that seals the driver pack's PCB was damaged from heat. I dug it the membrane out with my hobby knife and found a capacitor underneath. I bought a replacement capacitor and soldered it back in and covered the area in silastic. Time will tell whether this was the issue with mine all along.

    I got sick of driving on bump stops and plugging in my laptop to reset the EAS so I attacked my driver pack.



    Here's the replacement capacitor from Jaycar. 95 cent part:



    Now it's wait and see time.

    Mate

    I have a couple of those driver packs which look to be in better shape than yours !

    I'm happy to send you one so you can try it out

    If your 95c fix works, I'll send you heaps of driver units you can de-capacitate for me too ;-)

    I rekon you're onto something there mate! Good work.

    Cheers

    Cheers fellas. I have to give this time, I suppose 1000 to 2000 km, before I'm certain this was the problem. Again the only hard fault that I ever get is the excessive high pressure in the system. If it doesn't pop up again, then I will declare victory over the EAS!!

    Of course I'll try to update this thread.

    Good stuff mate !

    Sadly though my experience with electronics indicates that if one capacitor is bad then the others will not be far behind

    Well I've just come back from some camping up Dungog way. After some months and plenty of kms, I haven't had any EAS errors come up! So, so far so good!

    BTW, the 5.0 under the bonnet loafed up hills with bugger all throttle input. Just love the torque!!
