Using a memory saver cable

[Menthol]

If I use this cable using and external charger, then clean my throttle body. I presume the computer will keep the old setting. How do I "reset" the memory for the throttle body with this cable still on?

Thanks.

The only reason to consider such a cable, is to ensure the HVAC actuators don't head south after a battery reconnect.

But, keep in mind that EVERYTHING is still powered.

The other thing to keep in mind, is the polarity, BE VERY SURE the polarity is correct.

To answer your question, you need to pull all of the PCM fuses.

My , if your going to use this connection, save your money and leave the battery connected.

That's s the exact reason as you stated. Can I avoid the HVAC actuators heading for a vacation (lol) without using a memory saver?

I just redid my throttle body, because I forgot to disconnect the battery last time (in a bit of a rush). Reconnected with no issues, I have disconnected the battery maybe 50 times in the last 4 months with installing of my alarm, radio, other things that I needed it disconnected for. I cannot speak for everyone or I have been lucky with my carelessness, but I have never had an issue with any actuator. (watch them be jacked up when I go to head out later).

Might also want to look into removing the PCM fuses, someone with more experience may be able to give you better info though.

If you disconnect the battery, you do run the risk of losing an actuator. I don't know what the odds are, but most of us just go for it anyway. Sometimes, they can be reset by pulling the HVAC fuses, or by a 2nd battery disconnect.

Or, in the case of the throttle body, there should not be any power at the tb with the key off, remove the electrical connector and remove the tb

And, pull the PCM fuses when your finished.

i'd never unplug the battery to clean a throttlebody

It was my experience that the first time the battery was disconnected I lost an actuator. Once I replaced this one I have had the cable off a couple of times and both times, no problem. I think that if you have changed the actuator you shouldn't have a problem (the replacements are built better than the OEM's - I hope). Just my

My belief is that weak actuators need to be taken out and shot. Kill them on YOUR schedule, not in the winter time when you run the battery down and it's cold and then you don't get heat when you really need it and it's the toughest time of year to fix it without a garage and you're freezing your bippy off and misery loves company.

Coddling actuators out of nervousness is a wuss-out, IMHO. If one dies, it WANTED to die. Help it along.

Ok I'll stop being a wuss (maybe use it in winter IF I need to) don't want to be doing the change in -25C.
You guys have it nice, came back Thursday from Orlando, 6 days of 90F sunshine!!!!!

I agree 100 %. My went out when I had my remote start installed in Dec. Didn't know I didn't have dash vents until I needed them for the AC season.

I leave the battery hooked up and remove fuses 10 and 28 to reset the pcm.

Thanks for the info.

Don't you NOW just hit a couple of buttons on your Tech II?

BOTH of my rear actuators died when I did my alternator. I'll be disconnecting them to stop the ticking since the rear A/C will never work again and will set them permanently to give heat. Didn't work all winter and didn't really need it. If I ever do the front evaporator, I will replace all of them "just in case".

Isn't it sad that we have to replace parts "just in case", such as this and the coolant temp sensor?

What is sad, is that a lot of experimentation came with these vehicles; what is really sad, is that GM won't step up and make it right.
