what is the car doing?? by you saing "need a ECM diagram?" what is the problem with the car. that car is pretty bulletproof and I have't seen any ECM issues unless your A/C drain is clogged up and water leaked onto/into your ECM frying it up. Let me know what your symptoms are.

SOURCE: 1998 rav 4 ecu pinout location

sorry never done one so i havent a clue,in the good old days the tach connected to the coil wire but now with all this fancy electrics ,Well what happens is they call it vehicle security so they dont have to release the diagrams and this is done to stop people like myself from by passing the immobilisers when we service a vehicle.Because no doubt as you are aware on new cars that if you drop the oil the immobiliser cuts in.Change the battery and the same thing happens.So what happens to keep the dealers in work ,yes you have guessed it no wiring diagrams ,multilayered circuit boards and wires all the same colour to stop people like me from soldering the two outside legs together of a big switching transistor together to make the vehicle general mechanic friendly.Also encrypted software is used to stop the fault codes from being read ,they throw up the wrong code ?? try asking dealer to install then post where he connected too .,best of british with it

SOURCE: How much freon to put in the 1990 chevrolet c1500?

As long as you are using gauges, just make sure that the high side pressure is not out of the ballpark high... check cabin temp frequently and depending on ambient temp keep that reasonable as well (134 is not quite as efficient as r12 so don';t look for polar temps...you will blow it up before you ever get there.) 210-230 is average high side pressure, if I remember correctly. I've charged hundreds of units and except for very few, I couldn't tell you how much freon was used (unless using a charge station) Just following what I mentioned, I only had a problem with one (had a blocked condenser from the factory...so rare i actually remember it) Stay on the conservative side and you will be fine.

No voltage to throttle body on a suzuki samuri


this this all stock car, as most sammi are vastly modified, now.
common mod is put in Sidekick G16B engine.
so is it stock 1.3L?
that be first question, and if car is EFI and is stock or G16
the TPS needs 5vdc from the ECU.
if the ECU 5vdc ref pin is dead there are only 2 causes.
1: ECU bad.
2: this line is shorted.

1992 had 3 engines. 1.3 , 1.6 TBI and 1.6 MPI
throttle body or Multipoint injection (4 injectors) vastly different.
ECU TBI , pin a23 is 5vdc, if the map shorts, this can blow out the 5vde regulator,
ECU MPI. pin B6 runs only the TPS. sensors. (simple)

best practice here is to post displacement of engine,
and ECU part number. ECU suffix is all we need. and bingo.
I have all Suz, part. number, in my book. for all parts and all ECU.
(usa and canada)

The ECU shops (cardone is tops in USA) the first test
is the 5v pin, #1 off the dime. that.
the Sidekick ECU 8valve ECU. TBI , the 5vdc pin loves to burn the
pcb trace to kingdom come.
see that here.
examples see suz, page for 5v
http://www.fixkick.com/ECU/ecu-8v-sig-list/e76.jpg

see blown trace
the trace in front of this zener diode blows.
(usually customers hot wiring stuff (evil)
http://www.fixkick.com/ECU/5vdc-Refr-supply/56B30-5VDC.jpg

the acutal blown trace (and zener blown too)
is here see it, (if real sammi, it will be i different loc.)
this is a Sidekick G16A TBI ECU. 56Bxx
http://www.fixkick.com/look/ECU-secrets/images/33920-56B30_B15_damaged_trace-B15.jpg

how is that?
need more , ask /?

id bet cardone didnt check your ecu, (some fleabayer?)

You may be able to get that from one of the auto part stores online, or at the library. There are retail auto repair books for that year with wiring diagrams in the back.
