Does anyone know what this sensor or switch is? I cannot find it from the parts catalog. There are 2 of them. One each right next to the radiator. One is hidden under the battery.
Looks like battery acid (?) starts to eat the sensor that is located under the battery. I'll need a replacement part.
Yellow connectors are usually Airbag Squib Connectors.
Please unhook the battery for several minutes(and then some) as it says in the manual before disconnecting, probing, or tampering.
Last thing anyone wants to do is set off air bags or have a permanent airbag code stored.
Airbag codes on the RX330 are stored in the "Airbag Center Assembly" aka Airbag Ecu, and as far as I know some codes cannot be cleared without sending it off to get reprogrammed.

Quite expensive try cleaning them. They may fall apart when you go to remove the sensors.
Can't find them in Amazon or eBay. It's a >$130 part each. Ouch. Let me try cleaning it. Worst case, I'll look for one in a junkyard.

Big note to me: Unhook the battery for several minutes. Thanks for this. I hope it will not trigger a code after cleaning it.

Just to overemphasize, not only disconnect battery WAIT for 10mins or more.
Also: DO NOT USE OHMETER to check connectivity/resistance. These devices send out voltage which may activate the bg.
Last reminder: While working on them, make an assumption that the bag can deploy and stand clear of the way. If you remove the bag then position it such that in case of deployment the whole thing does not fly away ... let the bag open in space/air vs on the ground as it will propel it (if it expands and push itself up if it faces ground).
As far as I know, you will need to reset the ECU [stored error] which may require special reader. [my info is limited]

I'll turn the power on after disconnecting the battery and waiting 10 mins to drain any remaining capacitance. This works in other vehicles. I've never tried it in a Toyota. Hoping ECU reset is not required.
