Axis is going great, but just recently, I managed to open the rear glass tailgate hatch section separately to the main tailgate section quite a couple of times, but now it's stopped working.

I inspected the fuses, all are OK.

I inspected the mechanism (removed the inside of the hatch section) and moved the mechanism from the solenoid and it worked fine.

I suspect the solenoid, but would be happy to know if there is any lock or button I may have pressed in the interior which stopped it from working!

Do the solenoids have a habit of giving up the ghost, and how easy are they to repair/check (thinking of just applying 12v to see if it triggers...)

that switch is a fucntion of the BCM when then fires a relay which then fires the solenoid. so you are gong to be looking in a few spots. there is a control module in the gate that also runs most of this as well.

if its under warranty I would let someone else fiddle. if you are confident with a multimeter poke and prod the module in the back gate. you are looking for a 5v signal that drops to zero when you push that button. the gate works the same way. both of them feed a module.

Chris,

Any idea where the relay would be? I know where the fuse is, but not the relay.

Do you have a circuit Diagram?

Perhaps I should buy the translated service/car manual....

It will be behind the battery, firewall side. Take the battery cover off then slide the fuse cover up and check all the fuses.

I have the Jap cct diag open so I will see what it says...

Trunk lid opener? That fuse is in the drivers footwell, bottom right fuse, 10amp.

Mine has never worked either...

Ben from Northshore sent me a brand new release button, that I did manage to fit (only time the rear glass has ever openned), but that did not make a difference.

So it's either the control box, or the solenoid.

Have you had the rear door trim off? Its not hard to check the voltages.

Where are you located? If you can drop around I could check it out... Give me a pm.

I stil haven't got around to fixing mine. I still have to investigate the solenoid for the glass hatch bit of the boot.

do you know were that is because mine does open but only when you pull the fuse out then put it back in, the hatch button does not work so could just be that

Sounds like the switch is stuck in. Do you have a multimeter to check its operation?

now i think about it your prob right, no multimeter how would i check scotty if i can get one

Meter on ohms, unplug the switch and put the leads on the terminals/wires. It should be open and closed circuit when you operate the switch.

You should be able to buy a cheap meter for $5 or $10 off Fleabay.

Update.

I ripped the back off again with a friend who had a multimeter.

Switch is working.

Solenoid is working, but not getting the correct signal. Fuse is OK.

We think it's the BCM or what ever the little box is in the tailgate section.

Not sure where to go from here!

      V37 Radiator removal

      By Duncan · Posted

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
