Hi brand new member with complicated question
I have a 2013 rav 4 2.2 diesel, it has smart entry and start system, when I turn engine off by pressing button I get yellow flashing triangle with message ( check smart entry and start system) I have had a diagnostic check and the only error is B2282, which is something to do with vehicle speed signal cable - information does not match to bean - information, i have had an auto electrician examine it but cannot find anything, I asked a couple of toyota dealers and was told it might need a new cluster!! And they would want £1150 + vat for a cluster and £75 for diagnostics plus £150 per hour labour but they are not sure if this will cure the problem??
Anobody had this problem and got a result, thanks Stew 😊 aka local hero

Hi Stew….great to hear yer still around….say hello Chris. See me..? See if that fault only occurs WHEN you have described, and no other functions are adversely affected….
IGNORE IT…!

Stew have you tried the good old reboot of the cars electrics ? It’s amazing how many silly minor electrical gremlins it can cure !

Have you changed the battery in the key? I had a few glitches with the 4.3 system over the years which were all cured by a change of battery. Does your second key act any differently? |

Hi Chris and thanks, first thing I did was change both fob batteries and also main battery, searching many forums the only answer I have seen was a guy who took his car in to toyota dealer they had it for 5 days and eventually found a loose pin on one of the ecu connections!!

In that case, message SHCM ( who I think that you also know! ) |

Hey up Stew! Long time no see. First, have a look here: priuschat.com/threads/fix-for-dtc-b2282-after-homemade-acc-drcc-to-my-camry-hybrid.182579/It's a Camry, but it has the same check entry/start message at switch off and the same DTC as you're getting. We can no longer see all the pictures in that post, but that appears to have been a hardware fault in the instrument pack causing the same issue. I can't remember whether your 2013 is a late 4.3 or early 4.4? (as we usually say - FILL IN YOUR DETAILS! grin!) Anyway, a bit more gruesome info for insomniacs: The vehicle speed information is available on the vehicle in 2 forms: 1, It's broadcast on a CAN bus (complex-ish message thingy) 2. In a much simpler form than a CAN broadcast -> as a voltage waggling up and down on a wire at a frequency related to the vehicle speed. The main body ECU receives the information in both forms and this DTC is a result of the information from each of those receive paths not agreeing. Why it should complain about the entry system at switch off I can't fathom at the moment but the DTC is listed with Entry and Start in at least the 4.3 factory repair manual. It would also be useful to know which ECU(s) is/are storing the DTC. I suspect it is the main body ECU. My diag kit would tell me that but anyway........... The simpler speed signal is generated by the ABS/stability system. Effectively it's a cleaned up and probably 4 wheel averaged version of the signals coming off the raw wheel sensors. It's then passed from ABS to the instrument pack where the signal is simply buffered (or reinforced if you like) and then passed out from the instrument pack to several things like body ECU, navigation system, auto wipers etc. This DTC is allegedly associated with the connection of the signal between the instrument pack and the body ECU. I suspect the reason they can't say why changing the pack will fix it is because they can't use an oscilloscope and are just basing it on DTC readouts instead of looking at actual signal waveforms. Possibly the speed signal is outputting a few erroneous pulses at shutdown or the buffer has failed in the instrument pack or another ECU is pulling the signal low or it's just a simple connection problem. Can't diagnose any further remotely (unless you want a trip to the Black Country!). After clearing DTCs etc, my approach would be probing the speed signal at the instrument pack connector, body ECU connector and/or disconnecting a few other ECUs from the speed signal.
I suspect it's the "simple" version of the signal that may be the problem as I'd expect a CAN problem to produce a long list of DTCs.
Do you have navigation? Is it OEM? OEM at least (but some aftermarket can too) uses the simple speed signal and if it's missing, one tell tail sign is the location indicator not moving smoothly on the map. If I remember correctly you can also get the OEM unit to display the vehicle speed it's receiving, when the unit has been put into diagnostic mode. Might help diagnose.
Going off at a tangent - why do they have 2 versions (CAN and "simple") of the same speed info? Well: 1. There are some ECUs that don't have or don't justify a CAN interface that need speed information. 2. Speed info can be fairly important to vehicle operation and for safety reasons you may not want a "single point failure" of speed info to an ECU. 3. The speed info on the CAN bus may not be accurate enough for some systems. E.g. ECUs I've worked on, the vehicle had yaw rate info broadcast on CAN, but it wasn't accurate enough for our system, so we had to embed another yaw rate sensor into the ECU design. The 4.3 sometimes gave a false "key low battery" warning. Often when turning off by fuel pumps. I suspect interference off the pump was mangling the key transmission a little bit. (There's info in the message from key to vehicle about the key battery state - i.e. low battery or not). |

I always struggle to understand why so many things these days are made as complicated as possible. What was wrong with the old cable from the gearbox to the speedometer? Simple , effective and easy to fix when it broke. Maybe not as accurate as these space-age systems but it ain’t Apollo 11 we’re talking about here.
Rant over. I’ll get my grumpy anorak!😊😊

My huge apology to shcm for thinking he was Simon,only certainly not simple Simon, but more a very handy Andy, my memory is not what it was and I apologise, I have not had a spliff for decades, so why do I keep seeing huge crying emoticons everywhere 😢

Don't apologise Steve, I careth not.
emoticons have gone large at the moment. I *think* they may come from an external site, so the issue may be there or its a ProBoards (the forum host) issue.

Just an update so far still putting up with my problem but contacted a company who repair and refurbish clock clusters and sent them details of the fault, they have said that although they are happy to repair anything to do with the cluster, they do not think the fault as described has any relationship to the cluster, also I have, noticed mph and mileage seem to be very roughly about 10% out, seems that shcm is the only person who knows what the problem is Stew
