My Basic Schematics page, what you need to make engine RUN and some extras, for safe running!
100% USA (North America centric drawings.) Other countries can be different!
The Term Generation applies to USA Suzuki only. (other countries use different type motors and evolution rates)
Fuses are first, I use a voltmeter, keyon, and 12vdc across all fues (both sides hot), with headlights on, this can be a better test (a dummy load that)
1989-90 ONLY: G16A TBI 8V USA some times called SINGLE POINT Injection.
Generation 1 ; 8 valves. 1.6L TBI, Throttle body Injection. EFI, Electronic Fuel Injection only.
The ECU does not create or generate spark in any way shape for from, this car, the Distributor creates all spark all by itself.
In fact, the engine runs on test fuel, with ECU parked on your work bench parked there. ( DANG!)
A/T opted cars, have TB base heating device called a PTC.
This generation has no water heat pipes to the ISC.
A crude and Simplifed schematic page. (the MAIN relay guts are drawn all wrong, see next PDF link for truth.)
The clutch switch or (PRNDL) switch must close or there will be NO FUELING, PERIOD! (can be bypassed with a jumper)
more… fuse panel details at end of this page.
Generation-2, began here in 1991 through 1995 USA, Vin U is Geo code for 8valve car.
TBI 1.6L G16A 8 Valve ONLY motors, single injector engines: EFI, with water heated ISC.
1991 8-Valve only TBI Full schematic set. A Total set!
The 1991 unified Head light schematic, I made.
GM GEO oddity:
The GeoTracker calls 8v (only) ECU A pins the B pins, and Suzuki the opposite LETTER, so rename them to suit. A1 = B1, etc. as needed.
The colors were not changed from Suzuki to GM (GEO)
Schematics in common to both 8valve TBI and 16v MPI Trackers and Sidekicks. 92-95. 1.6 Liter G16A/B
Generation-2, The MPI 1.6L G16B. (4 injectors!)
Suzuki sold both 8v and 16valve motor cars starting in 1992. (Geo introduced 16v in Calif. in 1994 and all states 1995)
16 valve Multipoint injection MPI only. Electronic fuel injection EFI. 1.6L
Engine bay Component locations VIN 6 MPI, critical to motor running.
91-95 The DASH Relay and other electric module finder, including ECU and other controllers.
Daylight Running Lights (option in USA or for sure in Canada)
“DRL” modification’s (HACKS) or repairs.
I do not recommend defeating any safety equipment or DRL systems, here are the facts on most GM cars.
What you do, is your business and DRL is not mandatory in USA. (but in civil court anything goes!)
Hint: When you sell the car Undo all modifications.! (or add a switch,hidden,only you know about)
Generation #3 1.6 Liter EFI (not applicable to 1.8L )
Sidekick Trackers, are all 16 valve now. (USA) EPA reg.’s. FIRST YEAR FOR OBD2! In USA.
In 1997 (and 98) Suzuki moved the TCM into the PCM/ECU and the connectors and pin counts and pinouts are different. (I don’t have them) But alldata.com does.
1996 DRL Headlight schematic
1996 Relay and sensor locater maps. (errors revised) (mostly correct to 1998)
Suzuki moved many relays in this generation, some to the right side if heater box. (main and Fuel pump relay are 2 )
It’s all here below every detail, even the connector “pin-outs”.
The full 1996 FSM(extensive) the real factory service manual, covers ALL.
See power and ground wiring here and common faults, see link there for ground faults.
USA only below:
Suzuki pit stop
1996- 1998 DOHC 1.8 Liter SPORT (the wide frame car) SEE 1.8L differences page.
MPI EFI, Coil over spark plugs (COPS) and chain driven DOHC (2 cams) and MAF now moved to the Throttle body guts.
1.8 Liter Sport ECU schematic 96/97 old COPS
Coil OVER Plugs (spark plugs)
These COP parts can not be mixed. If you attempt to drive the 98 COP with a 97 igniter, you get 180degree inversion and the COPS burn to a crisp.
Suzuki Sports are very rare cars, only 9000 sold the laster year, 1998 in the USA.
Mitchell has the best data on this car, as does Alldata.com and books are near non existent.
Is the ECU bad? 8 tests here and how to fix all bad outputs and leaking Capacitors
EFI -electronic fuel injection, MPI = Multipoint Fuel Injection, TBI= Throttle Body Fuel Injection.
