Default ECM Info for Phase 3 Baleno 1.6(should be similar for our version I hope)

I am pasting info from other forum and it will be of great help to some ppl who love to trace ECM wires and its diagnotic.
This info is with respect to terminal arrangement of ECM (PCM) coupler when viewed from harness side looking at computer.

There are three connectors / looms connecting to the ECM each of which is a different size so you can't mix them up.

The left-hand one has 26 wires and is referred to as connector A with pins A1 through to A26.
A1 is at the top left going along the top row to A13 then to the bottom row directly below A1 is A14 then along the bottom row to A26.

The next two connectors follow this same logic.

B1 through to B16 on the second (Middle) connector.
B1 is at the top left going along the top row to B8 then to the bottom row directly below B1 is B9 then along the bottom row to B16.

C1 to C22 on the last (Right hand) connector.
C1 is at the top left going along the top row to C11 then to the bottom row directly below C1 is C12 then along the bottom row to C22.

I trust that makes sense!!!

Now to explain the function of each connection.
I have included the colour of the first few wires on each connector so you can tell you have the orientation correct.

A1 - Diagnosis switch terminal - (V/Y)
A2 - Test Switch Terminal - (V/W)
A3 - DLC
A4 - Duty Output Terminal
A5 - Tachometer
A6 - Main Relay
A7 - Check Engine Lamp
A8 - A/C Cut signal for A/C Amplifier (if equipped)
A9 - A/C Condenser Fan control relay (if equipped)
A10 - Blank
A11 - Power Source (for sensors)
A12 - ECM (PCM) Ground
A13 - Power Source
A14 - A/C on signal from A/C amplifier (if equipped)
A15 - Blank
A16 - Electric load signal for position lamp and rear window defogger switch
A17 - Electrical load signal for blower fan motor
A18 - Engine coolant temperature signal to TCM (4AT only)
A19 - Throttle valve opening signal to TCM (4AT only)
A20 - Ignition Switch
A21 - Radiator fan control relay
A22 - IAC Valve
A23 - CO Adjusting resistor (if equipped)
A24 - Ground for CO adjusting resistor (if equipped)
A25 - Power for back up
A26 - Power source

B1- Ignition coil assembly for No.1 and No.4 cylinder - (Br/Y)
B2 - Fuel pump relay - (Y/Bl)
B3 - Direct Clutch solenoid (3AT only)
B4 - 2nd brake solenoid (3AT only)
B5 - EGR Valve (Stepper motor coil 1) (If equipped)
B6 - EGR Valve (Stepper moor coil 3) (If equipped)
B7 - No.1 injector

B12 - EVAP Canister purge valve (If equipped)
B13 - EGR Valve (Stepper motor coil 2) (If equipped)
B14 - EGR Valve (Stepper motor coil 4) (If equipped)
B15 - No.3 injector
B16 - No.4 injector

C1 - Ground - (B/O)
C2 - "2" range signal (3AT Only) - (Y)
C3 - "N" range signal (3AT Only) / Torque reduction signal from TCM (4AT Only)
C4 - "P" range signal (#AT Only)
C5 - Engine start switch
C6 - ECT Sensor
C7 - TP Sensor
C8 - MAP Sensor
C9 - VSS (+) (3AT Only) / VSS (M/T and 4AT Only)
C10 - CKP Sensor (+) (without immobiliser) / CMP sensor (with immobiliser)
C11 - CMP Sensor (without immobiliser) / CKP Sensor (+) (with immobiliser)
C12 - Ground
C13 - "L" range signal (3AT Only)
C14 - "D" range signal (3AT Only) / "R", "D", "2", or "L" range switch from TCM (4AT Only)
C15 - "R" range signal (3AT Only)
C16 - power steering pressure switch
C17 - Sensor Ground
C18 - IAT Sensor
C19 - Heated Oxygen Sensor (HO2S) (If equipped) - (W)
C20 - VSS (-) (3AT Only)
C21 - CKP Sensor (-) (without immobiliser) / Blank (with immobiliser)
C22 - Blank (without immobiliser) / CKP Sensor (-) (with immobiliser)

Now to the specifics of Boskos question...

Hook the signal wire of your fuel mixture display to C19 which is a white wire.

For a kill switch you can use the fuel pump relay output at B2... just cut this wire and install a switch.

PLEASE READ!!!
Be sure to disconnect your car battery before removing connectors from the computer.
Be sure to disconnect connectors from the ECM before adding to or altering the ECM wiring.
Never install a voltmeter or Ohmmeter into the ECM connector’s terminals when the ECM is installed. (Disconnect ECM first)
Never touch inputs / contacts of the ECM with your fingers.

Basically I am trying to say the computer / ECM is a very sensitive and expensive item... If you are not sure about it don't touch... they are susceptible to ESD electro static discharge.

Default Baleno Trouble codes fm Service Manual

Attaching a pdf file so one need acrobat reader to read it.
Hope this helps.
Note:-It seems file attachment is not allowed in forum so I have uploaded it and link is ,

Hey karthik dude .. what say.. ? is this applicable to Indian ECU ?

Chetan , if you observe carefully all the points highlighted by you are off the 1.8L baleno engine sold abroad not in India .. So none of it holds good for our Indian version ..

Chetan, Euro 3s have heated 02s... Not sure abt egr or evap actuators, will chk on that.... And its not applicable to indian systems at least as a direct fit, but shd be possible with a little work.

Hello everyone, i am new here..

i have baleno ECM which have serial number 33920 60GB 1. made by Denso

it have 3 jack, 2 yellow and 1 grey.. do ECM wires up there is same with this ECM ?

or do you have other ?

thx

@wimasy, the first post by ECM is compatible with your ecu.

Looks like the wiring diagram needs couple of small changes..
B7 = Injector 1
B8 = Injector 3
B15 = Injector 2
B16 = Inector 4

@rdkarthik, thanks a lot.

do you have any technical document or other resource for this ECM ?

i will implant this ECU on my Suzuki Vitara G16 engine, the old ECM work with banking injection (2 injector on same time).

from your posting, i'm sure i will have great improvement, this ECM can use dual ignition coil.

I dont have any technical documents for that ECM.

Why are you planning to put this on to your vitara? If the vitara was using semi-sequential/banked injection, i am pretty sure your sensors would not be compatible with the baleno ECM.

Does your vitara have a distributor setup? What about crank/cam sensors?

Also note other ECMs may fit connectors on your car, but may have totally dfferent pin configurations...

@rdkarthik

yes, you're right, my G16A work on semi sequential, but i already install new sensor from newer version of G16A, which work on fully sequential injection.

i have crank position sensor, and my engine is already modified for distributorless system.

all the best for your project ..... just be extra careful with wiring and pin configurations.... let us know if you need any help..
