Happy days! Glad you got a ( inexpensive ) result! I love it when you end up with the same outcome but your wallet is not battered! Cheers Paul M.

Ask someone to view the rear brake lights and see if the 'click' occurs at the same time as the rear brake lights operating, as it may simply be the electrical switch defective/mis-aligned. paul m.

+1 on DIY, having retro fitted CC on the Mondeo then seriously this is a walk in the park if you know how to hold a screwdriver! paul m.

If you are happy to pay that amount to get this function then there you go! gotta say that price would irk me for the amount of work involved and the technical ability required but hey you'll get coffee and biccy's at the Lexus stealers. paul m.

I would ( and did) get amongst it and retro fitted CC that was very much more involved than this method, But, and a big but is if you are not confident on working with your cars critical components, then I advocate getting someone 'qualified' to do it. But yes read this thread from the top again to gleen more info. paul m.

Dunno about the Lexus, but on the Mondeo the Brake pedal had to have an extra switch fitted to disable the CC, this was achieved by splicing into the loom, but you may/may not have to do this. Read this thread from the start and it makes no mention of anything to do with break pedal, check parts list posted at post 4 or 5 and check this link out also. https://www.ct200hforum.com/forum/lexus-ct200h-general-discussion-forum/118233-cruise-control-installation-imgs.html paul m.

What the Toyota/Lexus or the Mondeo? The Toyota/Lexus looks a piece of cake compared to the Mondeo. paul m.

When you say you spoke to another dealer, I guess you only got to speak to someone who's job it is to answer phones and not the person with the spanners! Having read this thread and seen the video then I wouldn't have much faith in that dealerships answers to technical questions! paul m.

Gotta be the easiest retro fit for cruise I know of. I retro fitted CC on my Mondeo and it was a right palaver. Check this process out in comparison to the one shown in the video above!! https://www.fordwiki.co.uk/index.php?title=Cruise_Control_Retro_Fit_-_Petrol_Models Well chuffed when it actually worked and use it as much as poss now. paul m.

Happy days.... Gotta be one of the cheapest genuine parts out there! paul m.

Seller is now taking ‘Offers’ !!! paul m.

So..just found this..... Hopefully it is this piece and if so it is not a stupid price for a colour coded part! Lexus Genuine Part Number: 69217-53011 https://www.lexuspartsdirect.co.uk/parts/lexus-is/lexus-is-phase-2-o-s-door-lock-cover/ Paul m.

More info here, need to check VIN plate to determine if vehicle has a designed towing capacity or Not. https://www.towbarexpress.co.uk/maximum-towing-weight/

Pretty sure I have read that the IS range ( which prob includes the SC) is Not designed for towing. paul m.

You could try a 'soft' reset first by simply dis-connecting the battery for at least 10 mins and then putting in a nice fully charged one, this should allow any volitile memory to disapate and unless you really have got a fault somewhere then the error lights should be gone. A flat/low battery can throw all sorts of disconcerting looking errors! paul m.

That’s the only problem with ECP, returns from web orders is a right royal pain, have to get returns number from a phone call centre to return to a shop so best to buy over the counter if you can.

Glad you got it moving without much trouble. Keep an eye on the battery now, especially if it is cold as batteries, like me, don't like cold conditions and of it starts to show signs of struggling then it might be time to replace it before getting caught out in a more awkward situation. paul m.

Have you read through this? ( I haven't yet!) might be some links to sellers! https://www.clublexus.com/forums/is-2nd-gen-2006-2013/610678-frozen-navigation-screen-fix-diy.html paul m.

I too am a time served Electrician ( C&G 236 Electricial Installation ), started apprenticeship in 1980 for SWEB and ended up being 'pyro' King by the time I left in 1989 to join Fire & Rescue Service and have just retired after doing 28 years frontline firefighting there! ( ended up being HGV RTC specialist!). So from your background you sort of knew why the electrical demand was recommend to be placed on the defective battery car. I do not try and go 'too deep' when trying to answer people's queries on forums as I do not know their level of knowledge or their skill sets and people normally want quick/simple remedies! In my first job for example we used to work 'live' sometimes and although I would be comfortable doing that there is no way I would try to explain to someone else how to do it!!! Example, one poster on here ( shall remain anon) reported 'rattling noises' after 'doing' his front brake pads! Turns out after advising about caliper fixing torque levels and pad locating pins the road wheel nuts were loose! Really, how basic do you have to go when answering people's queries? paul m.

Whenever I submit any info on here ( or other forums I subscribe to ) it is either from 1st hand personal experience of the last 39 years of building/repairing and maintaining vehicles of all shapes and sizes or it is from a legitimate traceable source. I myself tell my kids not to believe everything you read on the InterWeb and I would always advocate gleening info from as many sources as possible and then make you own mind up! With regards to new battery EuroCarParts have stores nationwide and also deliver free, they are a bit like DFS ( constantly having a SALE!) but the discount varies almost daily! Do not buy anything from ECP without a discount code of some sort because their prices are geared to be discounted. You can sign up for codes via email and the current one ' PAT75 ' gets you 45% off batteries. So a Bosch S4 068 is today gonna cost £88.54. Del. Note: I am not affiliated in any way with ECP and other retailers are available! some recent(ish) threads on battery woes. https://www.lexusownersclub.co.uk/forum/topic/118032-need-help-with-is-250-battery/ https://www.lexusownersclub.co.uk/forum/topic/107731-best-12v-battery-for-is250/

Get them to read this thread then..... paul m.

Got that from the Haynes Manual ( Fiat 500, but common to all manuals!) that was on coffee table in front of me!! Reasoning I can see is this, If battery is completely flat /defective in casualty car then jump starting Will get car going yes, but on removal of good car's battery then casualty car may stop. So if casualty car battery is borderline completely flat/defective then maximum electrical draw will highlight this before perhaps you drive off thinking all good after the jump start. This bit of advice is now lacking from Haynes on their website 'Jump Starting How To' https://haynes.com/en-gb/tips-tutorials/how-jump-start-car

Check and double check,even triple check that you Do-Not inadvertently connect any jump or boost battery to the wrong polarity on your battery. Many a post on here ( and ten times more in the US!) of reverse polarity occurring and causing untold ( and £££££'s) problems. you may still have the factory fitted battery and at close to 7 years old it may be getting to the end of its life and this extended deep discharge may have tipped it over the edge. You could try giving it a very long low charge ( off the car) to see if can be recovered, but expect the worst ( new 4 year G'tee Bosch should be about £80) As for 'jump' starting a few basic's, keep engine of good car running, do-not allow cars to come into contact with each other. Attach Positive ( + RED ) jump cable lead to + (RED) battery terminal on 'dead' battery and the other end of the Red cable to Positive ( +) terminal on good car/battery. Connect Negative ( - BLACK ) jump cable to Negative ( - BLACK ) terminal on good car/battery then connect other end of Black cable onto a bolt or bracket ( Not Fuel related) on engine of dead battery car. Allow at least 30 seconds before attempting to start dead car and after it (hopefully) starts then allow to idle and then turn on Headlights,Fog lights,Heated Windows and heater blower fan and then turn off 'jump' car and remove all connections in the reverse order. Then turn off lights etc. paul m.
