It's not the 12V battery to the left of the trunk. It's located below the floor board of the trunk where spare tire (none in GS450h) is normally located. It's 12V as well but alot smaller than most batteries in other cars.

07 gs450h active stabilization battery replacement
Does anyone have any idea what the lexus part number for this battery is? I got the panasonic number off the top of the battery, but apparently that number is not helpful in identifying the battery for replacement. Also, is there an alternative battery that can be used to replace that battery. I know this is a lexus, but it is just a battery and I refuse to give lexus $400 for a battery. If anyone has any information on this, I would greatly appreciate it.?

Active Stabiliser - Flat Battery - error code C194E
Hi everyone from Auckland, NZL - I have a 2008 GS460 with the Active Stabiliser installed in the boot. I had my local repair shop replace the battery in Nov 2020 as part of a routine service check (they checked the battery voltage and it was on the way out) so I had it replaced. All good. Here we are now in Oct 2022 and the warning light has come on with error code C194E (I have an OBDII reader). Took it back to the repair shop to verify that the Active Stabiliser was the problem - sure enough - But, Murphy's law, the warranty is magically only good for 18months - this is 23 months, so I have to pay out for another darn battery - which, noted elsewhere in this thread is expensive compared to the ordinary battery used for the main car electrics.
A comment the repairer (in NZL known as the AA (Automobile Assn) - similar to RAC etc) made to me was that the comparable battery they stocked wouldn't fit as it was about 10mm too tall for the space available and would result in the floor panel and protective polystyrene not sitting flat - and this may cause other issues down the track. As a result they purchased a new battery from Lexus which cost me NZD$418 installed. Nearly two years later I have been quoted NZD$420 installed (not too bad given the rampant inflation we are all experiencing). The battery has to be ordered in so after a few days delay then I be back up and running again. I had intended to travel out of town for the weekend, but have postponed until the new battery is installed. While I am happy to potter around town not too far from home driving at inner city speeds, I didn't want anything to happen far from home or when driving at highway speeds.

Well, a brand-new Lexus Battery didn't do it. I even topped it off with a charge until it started trickle charging to no avail. Does anyone else have any idea how to get rid of this annoying Check Act. Stabi. warning? I have tried unplugging ground from both batteries. I hooked one up and then the other and then switched the one I hooked up first and second. I am at a loss here. Is there a fuse I can look at, there is 2 relays and 3 fuses in a box going to the stabilizer. Fuses look good, didn't test the relays. Most people got it going with a new battery. Am I missing something here. Thanks.

Have you tried hooking up an OBD2 scanner - running a test - seeing what codes appear; then clearing all codes - running it a second time to see if any codes re-appear?
Yes, unfortunately for you something seems amiss - as I had the code twice- and both times it disappeared when a new battery was installed in the spare wheel space.

C1911 Rear Main Realy
C194E Deterioration sub Battery
C1950 Non attainment to target angle in front stabalizer
C1951 Non attainment to target angle in rear stabalizer
These are the codes that pop up immediately after I clear all codes. I am getting p300-p306 random misfire codes, but that shold be unrelated. The only codes that come on immediately after resetting are the C codes. Thanks for your response! Any help is much appreciated. I did see a couple of relays and fuses hooked up to the stabilizer. Has anyone replaced the relays? The fuses look fine. Thanks.

Well, no go there as well. I am starting to think there is actually something wrong with it besides electrical. I just wish I could get rid of the warning at this point. I can't even see my MPG unless I hit DISP and then the warning comes back on within 5 seconds. I am going to try and flash the ECU to updated firmware from Lexus. If that doesn't work I will try and find a way to disable the warning through the MINI-VCI cable.
