Default Re: Please help with my top problem

I got your message, but prefer to answer in public, as this helps others as well.

Thanks for responding to my issues with the top. My last post indicates I have checked all the leads on the CPL/SSM and there is no sign of corrosion on any of the leads. I am at a loss of what to do next. You mentioned that there might be a bad solenoid for the electric lock. How do I trace this? Should I take the plunge and buy a CPL/SSM and hopefully that might cure the problem.
I have taken all the steps indicated in your posts and I just can't figure this out. I all comes down to the elecrtic lock not engaging.


I still think the trunk lock is not locking because the PTCM is not commanding it to lock because it sees somethat it does not like.
HOWEVER, your remark that the pump starts contradicts this, the pump WILL NOT START if the electric lock does not show "locked". It is important to know that, for years now, we have been modifying our cars so that the electric lock activates and tells the PTCM it has locked, but in reality it doesnt lock because we take the cam off the end of the actuator so the lock can THINK it has locked, but it hasn't. THis is to keep from being locked out of your own trunk when the power top system gets hung up part way thru the cycle. It would be a good idea to verify if this has been done, as this could be the cause for the confusion. Take the fuse box cover off, driver's end of dash. If on the underside it is written: "Lock disabled done" or "Trunk lock mod" or "Cam removed", then you know the mod was done and THAT is why the lock is not locking.

If nothing is written, you can LOOK and verify if the mod was done. Go to post #73 in THIS thread to see how to do that:

On the PTCM (Power top control module) connector P1 pins 21 and 22 are the lock indicator pins. YOu can determine the current status of the lock by checking with a voltmeter:

Pin 21 - zero volts when locked, 5 to12 volts when not locked.
Pin22 - zero volts when not locked, 5 to 12 volts when locked.


My big issue here is your indication that the pump runs. If it runs, what is the fluid level in the tank? Low fluid that is not TOO low will not prevent the pump from running, but the pump won't be able to get much done. The fact you say the pump does run makes me think you have a low fluid situation.

But again, you say when you hit the button "nothing happens" then you say the pump runs. I'm having a hard time understanding.

Meanwhile I will be hospitalized tomorrow and am prepping for that. I will be absent maybe till Tuesday.
