Thread: ACE Problem, Technical help needed.

So my ACE has had the odd problem.

First thing was one of the hoses to the front Actuator (ram) blew due a wearspot where it had rubbed. I removed the entire hose which run from the ACEControl Block under the vehicle about the “B” pillar to the Actuator/ram. I had Enzed make up a pieceof hydraulic hose and braise some fittings on the end of the fixed pipes toconnect the flexible hydraulic hose.

Before I get the dirt in the system comments, I made very very sure to keepeverything clean and dirt free. Everything I red online and in RAV has warningsabout keeping dirt out of the system.

Next thing the front ram/actuator started a slow leak. It’s been enough thatI have put about 200mls of oil in the reservoir over about the last 2 months.

I am ordering a new actuator/ram as the first thing to attempt to fix mycurrent problem.

My issue at the moment is just after I start the vehicle, it intermittentlyrocks to the left. There’s anywhere between 2 and 10 seconds between the bumpsrocking to the left.

Once I drive off, if the first corner is a right hand bend (leaning vehicleto the left) the red ACE light comes on with beeping. If the first corner is tothe left (leaning to the right) the orange ACE light comes on and the vehiclefeels like the sway bars are locked. According to the literature, locking thebars is exactly what should happen when a fault is sensed. I pressume that is done by keeping both Control Valves closed.

Nanocom says I have pressure fault. I'll have to reconnect the Nanocom to get the exact code.

I know many people have replaced the pressure sensor however I think thisproblem is more related to one of the solenoids. When I use Nanocom to turn onthe Direction Control Valve (DCV) 1, the vehicle bumps to the left about every2 seconds (guessing). When I active DCV2, nothing moves and the orange ACEwarning light comes.

I’m currently suspecting either I have air in the system from the leakingram/actuator or a buggered solenoid. Some **** wants $88 for a second handsolenoid on eBay but I can buy a complete S/H ACE Control block for $124delivered from the UK.

My first move is going to be replace the leaking ram/actuator and bleed thesystem.

I am currently open to suggestions.

Happy Days.

I have the Nanocom EVO and it has a bleed process in it without having to undo any of the hydraulics,they do warn you that the car will rock from side to side during the bleed process.
hope this helps a little

Ahoy Paul,

I know I dont need to disconnect the hyrdaulics for the bleed process however I do need to disconnet the sway bar links and extend the actuators. If I am going this far I might as well wait for the new actuator and change it at the same time.

Thanks for those that are offering advice.

The down side of changing the actuator, cleaning the filter and bleeding the system all at the same time is if it fixes my problem I wont know what it was that fixed it.

Actuator is ordered. I'll report back once it's changed.

Happy Days.
