remote central locking issue Options

[fenderdave]

Im having issues with my remote central locking, neither key fob unlocks the car, (1999, SR) I've found the security system ECU, behind the dash, but was hoping id just find a loose wire or something, all looks ok, dont suppose anyone has any ideas???

Its not alarmed, but does have the standard imobolizer which isnt activated (hazards used to flash if i unlocked the car manually rather than use the remote)

Also fond a box with Toyota TVSS just behind the gear stick, has a variable setting, but not sure what it does?

any help would be appreciated.
I have a couple of photos

hi fenderdave,

thank you for your reply. I read the pdf file you attached, and it looks like my alarm is too sensitive, and I need to adjust the radar sensitivity.

Can you tell me where the rador sensor is located? is it on the TVSS (which you mentioned is behind the gear box) or is it on the ECM (behind the dash) and how do you open up to gain access to the radar (ie how did you open up dash, or the gear box) did you have photos?

thank you very much.

tony.
