[Supras] Scantools

[Hacker J]

There is no data interface into the mkIII ECU, so the concept of a scantool does not really apply.

That said, Toyota did make a TCCS checker.  There was one for sale on ebay a while back.  It really does nothing you cannot also do with a paper clip and a decent DVM. It sold for $305. Special service tools like the checker are designed mainly to speed things up. The checker does make things easy but as an
EE I can do pretty much anything the checker can do with normal test
instruments. It does take a bit more time though. One nice thing about
the checker is that, in addition to testing the car's sensors and
wiring it can simulate them, thereby endowing the ability to test the
ECU itself for problems.

"You are bidding on a very rare item.... a Toyota factory diagnostic
monitor.  This was used by the Toyota dealers from the mid-80's to the
early 90's as the front line tool for TCCS engine system diagnostics. 
TCCS (Toyota Computer Controlled System) is the main engine control
system used on these generation vehicles.  Includes main unit, complete
instuction manual (100 + pages), and main wire harness that hooks up to
vehicle for testing operations.  Unit in excellent mint condition and
looks to have little, if any, use.  Also applies to ES250 and early
LS400 Lexus models.  Also included is a very nice bonus:  a TCCS
operations manual (175 pages) published by Toyota Motor that was never
made available to the public (nor was this tool).  In
excellent condition.    An absolute gold mine find for the independent
repair shop or enthusiast owner"

Anyway, I have seen some scantools that dig a little deeper, even on
OBD-1 cars where a paperclip does work for basic codes. Just wanted to
ask if there was any such tool for Supras....
