2017 Lexus RX450h 12v battery replacement

Following are the steps performed to replace the 12v battery in a 2017 Lexus RX450h F Sport.



So open the trunk and remove the cover and towards the left of the car on the driver side is where the 12v battery is located. To remove the battery cover push the three platic pins in with your finger.


Once pushed in the plastic plugs will be loose and can be pulled out. 


Then removed the red plastic cover which covers the positive terminal of the battery. The first step is to remove the connector attached to the negative terminal. There is a plug which can be pulled out (marked in red square, in the picture below) or we can loosen the nut that is shown below. I could not figure out how to pull the plug out so I decided to unscrew the nut.


Used a 1/2" wrench to remove this screw.


To loosen the connector cables used a 10mm wrench. Remove the connector connected to the positive terminal next. Also removed (pulled out) the breather plastic tube which is connected on the right side of the battery.


Next step is to remove the bracket which is holding the bracket in place. Need a deep socket wrench to remove the bracket screws.


Now just the lift the battery out using the handle on the top of the battery, Battery is pretty heavy. Battery cavity after removing the battery.


I purchased the new battery from Costco. Can't beat the price and ease of purchase. 



The existing battery had a plastic cover so swapped that to the new battery. New battery also has a handle at the top. 

Then it was just a matter of putting things back on, exactly in the reverse order. First attach the bracket so that the battery is secure. Plug in the breather cable. Connect the positive terminal cable first and then the negative cable terminal. While attaching the negative cable there would be a spark which is normal. Attach the additional cable that we had removed from the negative terminal.




Once done attach the red plastic cover over the positive terminal. Then put the cover back, attach the 3 plastic pins and then the main cover of the trunk. At this point the trunk cannot be closed by pressing the button on the key or the button on the trunk door or the button on front dash. I had to manually close down the trunk.

After starting the car the following amber light lights up.


The trick is to drive the car and then the light goes off. I went around the block and then it went off and stayed off. Now the trunk also can be opened and closed via the button.

That was it.

Outdoor wall light replacement

Image
Decided to replace the outdoor wall light (builder grade) with a more advanced motion detector kind and following is how we went about it. Purchased the new unit on amazon .  First and formost find the breaker switch in the breaker box and switch off the power to the wall light. Then in order to remove the current or old ligth fixture, unscrew the two screws as shown in the picture below. Remove the mounting bracket and unhook the wires. There should be three wires, a black wire which is the hot wire, white wire which is neutral and then a bare copper wire which is ground.  Then attach the bracket that came with the new unit. The unit also came with two screws to be connected to the wall connector box.  Next step is to attach the wires from the new unit to the wires on the wall. Use the twist-on wire connectors that came with the kit for the black and white wires. The bare copper wire is connected to the metal bracket or holder and the loose end is capped off with the twi...

GE XL44 Oven Igniter replacement

Image
 The other day my daughter was trying to bake a flan - her very first attempt in our oven and the oven would not heat up and thus started this DIY repair. Scrolled through a few videos on youtube and learnt that  the most common problem is a burnt igniter. Did not do much of a diagnbosis if that was the case here but on hunch started to take the oven apart to see if I can get to the igniter.  First step is to remove the door. Just open it a little and then slide up or pull up towards you in order to remove it. It just slides up from the two brackets on either side. There are no screws or anything securing the door. The door is heavy so make sure to grab is firmly on both sides. Then remove the metal drawers or shelves and also slide out the bottom compartment. There are tow screws at the back, remove those with a flat head screw driver. Once off remove the bottom cover. Pull up the cover from the back of the oven a little, pivoting it on the front edge and then slowly dis...

Prius 2010 headlight replacement

Prius 2010 Headlight replacement - driver side. Both the main headlight and side light on the driver side stopped working. Luckily high beam light was working. Positions of the bulbs shown below. After opening the hood getting to the bulbs and figuring out how to remove them is a little tricky. The driver side is relatively straight forward once you figure out what is what but the passenger side is very cramped and might have to take a few other elements out of the way before one can reach the bulbs. As indicated in the pictures above the main headlight bulb is a halogen bulb (and the high beam one too) and has a wider/thicker connector whereas the side lamp is a smaller regular bulb. The oritentation of the side lamp bulb is kind of up right whereas main headlight is horizontal. Turning the connector assembly quarter of a turn removes them from the slot. Remember the oritentation of the connector as you remove it as it will go back in the same way. There is only one way to remove it a...
