I am having problems with the rear view camera on a 2005 ls430. When I go into reverse the screen changes from map to blank.

I have removed and opened the camera. I found no signs of broken wires or bad connections in close proximity to the camera. I found no obvious sign of water damage inside the camera itself.

I have an Autel diagnostic computer that includes a toyota/Lexus diagnostic port adapter in addition to the standard obd2.

I was unable to enter the camera diagnostics through the obd2.

If the second diagnostic port exists, where is it?

Any tips on helping me to decide what part to replace?

Thanks,
Jay

I believe the second port is under the hood.

Nope. It's not ls400.
you need real toyota scanner/techstream to diag this, sorry.
only one DLC3 port, under the steering.

One port is under the steering column as normal. The other is in the engine bay. This applies for both the 400 and 430. What kind of tools you need to read from these ports I do not know.

There's a small fuse box in the trunk on the left side. Check the 7.5amp fuses.

Thanks for the tip about the fuses. The bad news is they are all fine. The good new
s is I found the strobe control.


I have spent a good while looking around the engine and failed to find the diagnostic connection. Here are a couple of engine pics. Anyone know where the connector is?

I could not get the image to display directly in the post so it leads to photobucket.

On my euro there's no second connector in the engine bay...

jaywish

Also...

I ran the diagnostic check thru the nav unit everything came up "OK" Then I select recheck and Camera-C comes up "NG". So it told me there is a problem but not what the problem is.

The sun screen and side view mirrors react properly when I switch into reverse.

I am hoping that when I get the computer connected to the 2nd diagnostic port it will give me more info.
(if there is a second connector)

Lynzoid

Nope. You need toyota IT2 or Techstream and connect it to DLC3 under the wheel...
My guess would be to check connectors once again.

jaywish

Can you guys see the photo's? I could earlier, now I can not.

jaywish

When you say DLC3 is that aka the OBD2 connector?

jaywish

The autel computer that I am trying to hook up communicates with most auto systems. Most but not all. For example it will not read the convertible top system on an SL500. Every other system I have tried to read is yes but that, no.

DLC3 is a data connector by toyota. it does incorporate some obd2 compatibility re:engine, but that's about it.

jaywish

I believe you are saying Toyota integrated it's proprietary data system connector into the required OBDII connector and all body systems are now accessed through one combined OBDII/DLC3 connector?
