Hi,

OK, so had my "TRC" query answered - thank you Dylmrt.

Moving on to the second question:

My rear tail/brake sockets are currently configured to be single filament globes for inner brake lights only and dual filament globes for the outer tail/brake lights............however, the outer brake lights on the dual filament don't work. All the wiring still appears to be original, so I don't understand why they wouldn't work.

Would anyone have any thoughts on why the outer brake lights would not be working?

Cheers, M

TRC generally is the traction control system. Very few SW20 came with this though?

Thank you Dylmrt,

Obviously has nothing to do with my rear brake lights then :-)

Cheers, M

Are you 100% sure the bulbs are ok 

My suggestion would be a little bit of diagnostic work on the connectors going into the light assemblies - make sure you actually have power where it should be when you press the brake pedal, and when you turn on the tail lights.
 
I'm presuming that Obvious Check #1 has been done (that the bulbs are all good)

Yep, bulbs have been checked and I have bought spares and swapped them over to double check......... I am blonde so understand your statement about the obvious!

I might have to get an auto electrician involved - don't have the necessary tools to do power check on the wires.

Cheers, M

I assume your car is the Aus delivered model?My car brake lights act the same as you described. So maybe its normal?

Yeah, mine is AUD - strange that all the fitments and bulbs are setup for dual lighting but don't work. I am getting Toyota to check it for me today, so will know tomorrow if it has something to do with the way AUD's were wired.

Cheers, M

 
For whatever Toyota wisdom reason, JDM light up across the four on braking, ADM the inner two only as shown in the pic.
 
(BTW, a 'subject change' screws up all the responses for your original question - just start a new thread!!!)
