2009 Toyota Landcruiser Sahara LC200 Turbo Diesel

[luke0011]

Ok I have some info regarding the 2009 LC200 Sahara Turbo Diesel SatNav System. September Release Imported Navigation.

In regards to adding a 2nd camera that automatically switches between LC camera and caravan camera when caravan trailer plug connected. As well as supplying 12volts to the reverse wire while isolating the reverse bulbs to switch or force the camera image to be seen while driving.

Problem: All works fine except for 4LO, Engine light and traction control warning lights coming on and stay on after 3 ignition switches. Then have to disconnect battery to reset it. The reason is because 12volts and not a resisted earth that the reverse wire should see is present. There is not a 12volt reverse wire going to the Fujitsu Ten screen. Bugger spent all day on it. Even removing the camera on while driving relay did not solve the problem (bottom one). The reverse wire still sees a resisted earth through the relay when caravan trailer is connected and reverse is engaged. I can only assume that the CAN BUS system is reading the irregularity on the wire and reporting a fault. It also permantly turns on the brake lights when the warning lights appear. Damm CAN BUS!!!!! Any help would be nice. Prolly a CAN BUS interface which is not yet made. I did recieve the wiring schematic for the earlier 2009 release Fujitsu Ten screen which stated 26 pin white connector right side at back of screen pin 13. But this Fujitsu Ten screen is different and i tested every wire and there is not a 12volt reverse wire going to it. Where's my CAN BUS magic wand!!!!!!
