-gotcha. will try DLC jumper and get back. have done this in the past with the VSS issue, although it was a looong time ago.

It is  not OBD1, (there is no world standard for any OBD1) it is SUZUKI Only oBD1, and nobody makes scan tools for it. nobody. (OTC over the counter)

i think its OBD1 (although made in 1998) because its european/santana made.  correct.
have used various professional scantools at local car repair shops (just for the sake of it) in the past with 0 success on actually communicating/connecting to ECU. (fail it will) 
-sounds like master yoda`s voice to me, but thanks for telling me this: i had no idea obd1 was specialized by individual auto-makers.

what you need to do is insert the DIAG jumper in the DLC jack and drive for a week with code 12 flashing (12 - happy good)
then if something bad or something fails intermittently , you know know why the CEL was glowing before.
like the codes for idle switch set wrong and TPS not calibrated correctly.
-hmmm, then maybe i should recalibrate TPS -although i have a feeling its electrically involved issue, because i mangled and twisted a few cables here and there while replacing the coolant hoses. nothing serious (or visually profound), but thats my wild guess atm.


-oxygen sensor is 4 years old (genuine denso), same applies to spark plugs (denso iridium), spark plug wires, dizzy cap and rotor too.
the O2 sensor front (02S1) will fail (not bad) with any cracks found here, shields off the exhuast manifold see rear tube cracked?
-no cracks, i had a new header (stainless steel), new cat, new muffler and new piping installed last year. 0 leaks (and i check for any kind of leaks every time i change my oil & filter; every 6months that is).
sure and what  great first post,  super good. nice history and all,
car runs great?
MPG good, 26-28mpg USA or  11 Kilometers / Liter ?
full power up hills.?
-i get about 8l/100km on european 95octane gas, which should be like 30 or so mpg?
-i experienced full power only after i replaced the injectors. about 20% more power (butt-dyno). 


tps idle switch calibrated? per manual. (feeler gauge horrors, tedious) we know what to do ask.
-i did that 5 years ago, but maybe its time to do it again?

drive with the DLC jumper planted.  DLC 4 pins,  B to C jumpered like this.
https://fixkick.com/CEL/DLC/DiagJump.html

the rule on this DLC do not drive with jumper on other pins, that is bad.
but the DIAGNOSIS pin is safe,  as it does not change running states, it only adds blinking CEL to the mix.
all the best to you and your Spanish car ! and most welcome you are.
-thank you! FYI, engine engravings on the engine block say 'made in Japan'. Wink

wow 8liters is super super good mpg. no lie .
butt dyno's rule!

yes Iwata japan ships engines to many suz assembly plants,   even our old closed,now CAMI plant in Canada;  (with uSA radiators ,tires, glass, wipers , battery and more... oddly)

i always look inside any ECU first. for cap warping, even pull the corner one and measure Ufarad's, with my meter, but once pulled my head goes.  gee I have spare caps.
why do this twice,  then for sure with super good new caps. (imo)
your caps may be heat sensitive, ok cool fail hot or reverse.
they (caps) are all  mostly 20 year rated, the caps are the shortest lived parts in electronics (just below batteries) just electrolytic's, not the others.

reCAPing  old things is not new, everyone does this on computers, cars,  and even my ham rigs. (relics 1975, one is 2,400v caps here... yah lethal )

Possilble:?
One more cause,  someone hacked the speedo cluster wires using wrong cluster and all have different connectors so some wise guys hack good speedo and hack the wires to find your
16v car. (the clusters are super variants, see my cluster H3LL here.)
and now CEL is wired wrong, or shorted to ground do to some odd things there.

we do know the Santana   flash out DTC codes, for sure. whit that jumper. ( colored wire)
