Tns510

[tarquin]

Hi all

I'm putting this information on here for people who may wish to fit an aftermarket camera to their TNS510 at a fraction of the cost of an, IMO MR T's ugly one. The reason for putting it on here is that it gets picked up by the google search engine. I could find no information what so ever about the TNS510 so all the work has been done by me and many hours of experimentation to see how it functions.

OVER VIEW

For the TNS510 to accept a camera input, a few things have to occur. Firstly, there are 4 connections at the rear of the unit pins 27,28,29 and 30. They are colour coded, RED, WHITE, BLACK and screen (braided wire)

Now you would think that they are obvious connections but they are not. When the unit is powered up from !st and /or 2nd stage ignition, the unit produces 6v on the BLACK wire and the negative side being the WHITE wire. Now unless you are going to feed MR T's camera which is an unusually 6volt camera, these 2 wires can be ignored,either taped up or left in their connector sockets. The one's your interested in are the screen and the RED wire.

The RED wire is Video In and the screen it what it is, the shield for the video signal.

This is not the end of the story. For the unit to switch into camera mode, a 12volt supply is fed from the ECU via control function by actuating reverse gear. This is where I had problems and upset my ECU.Normally 12volts would have been switched when the switch in the reverse gear lever was actuated rather than a low level command the ECU.

By just using the RED and screen wires and powering the camera from a switched 12volt supply (i.e the auxiliary socket below the A/C consul via fuse) all works fine when you choose reverse.

The problem was I wanted to switch the camera on whilst not in reverse.

When the gear is put in reverse, the 12volt switching voltage is sent from the ECU on a green wire in a grey socket to the unit. One would think by emulating this 12volts you could switch the camera on.Well that is what happens except it brings up engine management light, air bag light and VSC alarms!!! whats worse is that by removing this 12volts the alarms still remain and switching the ignition on and off doesn't clear them.!!!.

Fortunately, by removing the Battery for 30mins resets the ECU and resets stored memory.

So what do we do?

You need to make sure you have cut back and revealed about 4inches of the green wire and cut it. Solder a 1n4006 diode between the 2 ends you have just cut. Anode towards the ECU feed and the Cathode (stripe) towards the unit as in my diagram. Also soldered to the unit end is the switched 12volt feed again via a 1N4006 diode as per my diagram.

Now with the first stage of the ignition on you can operate your bypass switch (which i mounted on a spare blanking plate on my dash board and illuminated it) and the camera will come on and no nasty alarms. Works perfectly.

The diodes are included to stop your switched bypass 12volt feed going back down to the ECU and upsetting it but only going to the TNS510 to switch it into video mode.

A couple of other bits of information. The 6v that you are not using, is only active for 30 seconds. I suspect MR T must think you must of reversed by then. Also the screen will not switch into video mode even with the 12 volts on the green wire if the TNS510 doesn't see a video signal from the camera

So if your fuse blows feeding 12volts to your camera, you won't get a blank screen, you will see no change on the screen

All clear? Good I'm not expecting lots of comments its really up hear for people to search and find and hopefully help them

Hi David

That sounded a fairly lot of homework in getting the camera to work. The position of the camera is very neat in the number plate.

Show you it all when I see you. what colour is your internal light? is it totally grey or is it 2 tone , grey and sort of chrome.

Thank You!!

I wish I found this guide earlier. It took me a month to fit the TNS510 back in and connect the camera.

[tarquin]

Thats because i am a Genius. Ha ha

david.

I have followed this most excellent guide, but am still having problems.

I dont have anything plugged into the grey plug, so my car is obviously not giving a signal for the reverse.

I tried just putting the 12v onto the pin where the green wire would be connected, and nothing happens. I was expecting to see the screen blink whilst looking for a video input, but nothing.

When I go into the hidden menus, the camera input is greyed out. Have you any idea where I go next?

[tarquin]

Hi

I am assuming your looking to fit a rearviev camera. Have you seen the installation instructions for installing the original Toyota camera? Not only does it come with the camera and mounting but also the grey plug with 3 wires on it which have to be connected to various points on tbe connectors under the kick cover in the footwells. These wires put conditions on the grey socket for the camera to operate under certain conditions. When reverse is selected, a control signal is sent from tbe gearbox to the ecu which in turn sends a 12v signal on the green wire on the grey plug. This momentarily puts the tns510 into A/V mode and looks for a video signal. If in 1second it doesnt see a video signal it ignors the 12v command and reverts back to map or what ever it was on before the reverse gear was selected. One note, you dont need to go into the "secret menu" when installing a camera. You can buy the grey plug withetge wires on it seperatly. Look for the tns510 installation guide for the part number. Pm me if with a phone number if you want a chat about it

Just found the part number for the lead you need

PZ445-00333-00 Think it was about £15

Hi David, just read your post and thanks for all the info given. I am thinking of installing a reverse camera to my TNS510 and would like to know which camera model I should purchase as there are NTSE and PAL models available. Which camera did you use?

Regards Marco

[tarquin]

I used a Pal one but people have use a kind of hybrid of both. If your using a 12v available just about everywhere for £5. Because of the way the Tns510 looks for video there is a small time window for it to see video from the camera. The original reversing camera from Toyota is 6v and is supplied to the camera from the Tns510 when reverse gear is selected. In about a quarter of a second after power is supplied, the Tns510 is looking for video. The screen blanks for a split second. If it doesnt see video it drops back to map. The very best way to power your 12v camera is to power it from the ACC supply i.e when the ignition is on. You can use the back of the Aux /cigarette lighter socket. This ensures the camera is sending video constantly to the Tns510 but only displays it when reverse is selected. Dont worry it wont wear out mine is fine these past 4yrs. Take a look at the installation instructions of the original toyota camera. Behind the Tns520 there is a sleeved cable with 2x black wires, 1x red and 1x white one. The video from the camera goes to this cable. The video screen goes to either of the black wires and the centre video wire goes to the red wire. The white wire is not used and has 6v on it when reverse is selected so tape it up out of the way. Dont be tempted to power the camera off the reversing light because when reverse is selected there is a small delay for the light to be powered and by the time the camera gets powered up, its missed the window the Tns510 was looking for video and drops back to map.

Hi David,

I have 2 Toyota iQ, the first one had the TNS510 already fitted when I bought it but for the second one I bought a used unit without cables from eBay. I was able to mount it and it is working now, but I could not found the gray calbe (so I improvised something to keep the pins in the socket but don't really like to let them this way). The part number you mentioned seems to be for the full TNS 510 kit, so I am wondering if you are able to find the right part number. I already tried without real success in various ways (toyota docs, spare parts stores, etc... ).

If there is no part no for this cable, even a blank plug will be enough (I will add the pins that I have already fitted there) but I need something to look after, I don't know what is the reference of this plug. In all the docs I was able to found about iQ (also with wiring schemtics) only the normal radio was described, not the SatNav. I also looked in a engine bay wiring loom I bought from a scrapped iQ (with regular radio) and could not found a similar plug to use.

Any hint will be highly appreciated, thanks!

don't know which cable you mean but does page 6 of this help at all? https://www.toyota-tech.eu/aimuploads/{4DC3ED24-FB59-EDEF-D0DD-9CC5112DFB59}/IQ_TNS_510_RHD_PZ445_00333_00_AIM_001_388_2.pdf

[manu_cyb]

Thanks, it is the cable "B" in the page 6 of the document.

The microphone cable has the part number: PZ4450033302

I also found a reference for "SPARE WIRE ASSY TNS", part number: PZ4450033304 (can't confirm it is what I need)

and another similar part no for "SPARE INSTALLATION K", part number PZ4450033303

[manu_cyb]

Question answered (and cable ordered). The part number is indeed PZ4450033304.

In the attached picture you can see the part numbers for this one and for the microphone cable.

Hi,

How would a camera get 12 volts, if the dashboard switch is off? This is during the situation where reverse gear signal is used.

[tarquin]

Hi 

i installed a aftermarket rear camera in my number plate. 

In normal operation, when reverse gear is used, a voltage it put to one of the pins in tbe Tns510 and switches it to A/V mode and it is displayed. There is also camera pins to consider. Thereis also a short window when the tns510 looks for video on its input. If it doesnt see vidio in something like 2 seconds then the blank video screen switches back to map

so its best to have the camera with 12 v on it all tbe time the ignition is on. Then it will be sending video to the tns510 ready for when you select revers
