actually it depends on 2 things (besides, vitara/sidekick/tracker and G16s)
it depends on country, (called market and there are up to 54 ECU to cover all markets, (countries)
the rules are dictated by the country sold, not by suzuki , unless the country allows, E01 or JDM cars into said country or state.
this is how all cars work, world wide, all in 1 paragraph. see?
The op car is USA spec, market car, there are 2, the FEDERAL and California.
I think both are same , and both are G16bs and have a calif, ecu or fed ecu under the dash and for sure, sets all rules and logic here.
1996 in usa, if that is the location , by law changed to OBD2, (by law and is our system, we invented, OBD2,, and how it works)
the EGR only activates moving, (car most be faster than 1 MPH) and must not be at idle, (idle switch must not be closed to have EGR flows)
The EGR VSV at the instant , opens up sending ported vacuum to the MOD valve and this valve , if the cat is not missing modulates all flows of EGR exhaust to port 4 in the exhaust manifold
the ECU also (by OBD2 edict) has 2 monitors on this action, mode A and B, as stated clearly in the free 96 FSM listed here, ask if cant find it, please.
Yes, there are other requirements, hot engine, and closed loop, and NEVER AT WIDE OPEN THROTTLE.
Not to mention that ADDED VSV on the rear of the intake man. this is OBD2 level mandated VSV, this allows more intelligent EGR monitor tests, the ECU opens it to do the tests. this proves which end if the complex system is failing.
There are vacuum rules too, all clearly called out in the spec. (hot engine etc, the 2 pages below tell you the preconditions and how it works)
here is mine.
but is not looking for an rpm drop, the ECU has its own EGR BARO (MDP) sensor now, only on USA cars, and is used to see the vacuum change, at this sensor to prove the EGR works or not (OBD2 laws). in BOTH TESTS. one test is cut fuel test, and one is cruise test. per the book rules.
lets now look at GEN 3 (USA gens, not world wide) if not in USA you must state that or all answer by me will be WRONG, for sure.
http://www.fixkick.com/EGR-Gen3.html
now the rules for the test.
the system can fail 3 ways, (basics) Electric, vacuum and exhaust paths.
we first find which of the 3 it is, its not hard to do or magical;,, we do the stall tests and bark tests first, so see WHO is messing up first.
or its going to be a LOST WEEKEND again.
here are the 2 , OBD2 tests.
off that same page.

these are facts, and the first question to ask , is how to tell if test A or B fails.
easy the FREEZE FRAME tells you that !
test A is cruise
test B is the deacelleration test, cut fuel mode.
as you can see by federal edict, they check that the flow is zero cut fuel and flows correctly cruising, they check that the valve opens and closes by law now. before in 1995 , they checked only heat, and only with valve open, and can be fooled easy, it never checks cold , ever. (bad that was)
OBD2 changed everything... (can talk all day on OBD2)
I guess you missed my page covering all that to the huge extent, your USA car has the OBD2 mono port intake for EGR.
others (countries) use the 4 ports in intake manifold all other non USA cars. do this year.
see this page yet?, its been here for 10 years now.
http://www.fixkick.com/EGR-choice.html
see the 4 generations?, I can do more, if asked for ever newer cars, with electric EGR. sure can , like the 1996, up , SPORT 1.8L or 2.0L DOHC engines.
do the stall test, yet? If JOrgi did it would have failed, telling you its the exhaust side failing (1 of 3 possible so just saved yourself 2/3rd of the work)
stalls or nearly stalls, if you see NOTHING we fix that first. see?
is the egr main diaphragm stuck, (cold engine, using index finger press the ring seen on my EGR page (index to EGR) it most move about, 1/4" or 6mm. if not its jammed and hopeless this valve fix it or buy a new one. most are stuck or sticking.
we can do this 1 simple step at a time. or read my pages on EGR.
keep in mind if the CAT is missing, all hope is lost. or rodded out, or blown out. or gutted or missing. (IT must have spec back pressure , must)
I use a hand vacuum tool on the EGR main nipple to get it to open if that fails, manually index finger it, cold engine, ah its stuck this takes me what cold to hot. 5min work.
the in 30seconds do the vacuum stall.
is this hard work?

The computer is looking for an RPM dropNO. I think when you start driving, you get the egr test, and at the first stop you make, the car stalls. I tried all the things presented here, but from time to time I still had that stall. While working on something else, I needed to remove the throttle body from the plenum. Inside there I found 1/4 inch of thick black goop. When I cleaned that all up and put the car back together, the stalling problem was gone. We have seen 100s of monoport blockages, endless....

your were lucky, my 97 had ever pipe , packed, end to end,,,, (and was caused by LImphome, ignored by PO)
