VTSS 80 series security system

Allright it's like this then,

I just upgraded from the mighty 2H 60 series, (Reliable, solid, capable, strong, slow) to a 96 GXL turbo diesel, (I only just drove it home two days ago and so far it is, powerfull, and I expect it to show the above traits and more over time...) but I have a few questions that I hope this forum, and it's members can help with.... from my reaserch I believe this car should be equipped with Toyotas security system TVSS, the previous owner told me how it would automatically lock it's doors after a period, and it came with a two button control pad with the keys. however I have no other doco and cannot figure out if or how the system works. If anyone with a simillar vehicle could give me some clues, or direction I would really appreciate it. secondly, it should also have ABS brakes, (has the fuse under the bonnet and all reviews indicate it has ABS), however the ABS light does not come up in the pre start instrument check, (neither does the diff lock light) so is it a big job to check the bulbs(ie pull the dash apart) or should I bite the bullet and take it to toyota for investigation??

cheers
