Hi,

The Maruti Swift is officially supporting the newer CAN BUS Protocol. It was splashed in all their AD's when they announced the car.

Hello Manik,

I have 2006 Swift VXI. I would like to own a OBD2 toolkit. Following your instructions, I have narrowed on the following toolkit:
OBD Diagnostics, Inc. - OBD2 All-In-One Scan Tool w/ USB

But I would like to know whether if I manage to get it, I can connect and use with Swift?

Appreciate if you could PM your contact.

Thanks.

Maybe you can try the ELM 327 based used tool it is available in India with these people ELM 327 USB | OBD-II Scantools | iRide Technologies

Sorry for reviving such an old thread, but can anybody tell me if Chevrolet Spark is OBD compliant or not ? Just curious....

I think it is coz my dad was saying that the service center guys connected a laptop to some place near the steering and got all the details.

anku94 · 26th January 2010, 22:23

I found this port in my car. It's some diagnostic, I'm sure of that. But is it OBDII ?

Assuming it is...are GM Daewoo Spark OBDs standard ? I mean, do I need a scanner to read this ?? Or just a serial cable would suffice ?

pranavt · 27th January 2010, 02:52

Looks very much like OBDII, yeah.

driverace · 30th January 2010, 02:37

( I seem to remember, of reading somewhere, the Skyline became a overnight star in Drift championships owing to its wide-ranged-remapability of the ECU thr a simple lappy connection from n00bs-to-geeks!
can anyone share some more on that?)

Other than ECU interfacing/data reading,
I was also thinking more on the line of a suggestive/interactive role of the Carputers, what I mean is:

Inputs:
-Engine temps (multiple points- with history)
-Coolant inlet/outlet temperatures (in correspondence with above point)
-Brake callipers reading (read- travel/retract positions) --determine sticky pads/ change requirement based on increased travel !
-Speed picks from 4Wheels ( to get history of driving Vs relative responses-- may be to prove that ABS works/worked at XX time !!)
-Tire Pressure monitoring ( remind air fill / alert a puncture /or even over inflation due to continuous runnings!!)
-Door lock-feed (safety!)
-fuel level ( real time fuel indications - mark patterns of fuel consumptions!!)
-Auxiliary power use in car ( ICE+A/c+Headlamps+Carputer itself!+others)

<too much !! I know!!>

-Gear shifts with rpm and torque at shift points ( history- perhaps may help us fine tune our driving style/perfections!!)

-Clutch/Accelerator/Brake lever travel wrt the respective effects curves !!
-remind Oil changes/fuel refill due periods + probable vibration sources if any
-Ground clearance monitoring with loads/ brushing of tyres to sidewalls!-alerts
terrain identification/warnings!!

Can we think of achieving these ?! (quite a lot, I think, but surely not out of reach.. when we are already installing carputers here!!)

Care.

OBD Types.

J1850 VPW--The connector should have metallic contacts in pins 2, 4, 5, and 16, but not 10.
ISO 9141-2--The connector should have metallic contacts in pins 4, 5, 7, 15, and 16.
J1850 PWM--The connector should have metallic contacts in pins 2, 4, 5, 10, and 16.

If your vehicle has this style connector, but doesn't have these pins populated, you probably have a pre-OBDII vehicle. To add some confusion, even having the connector with the contacts shown above is not a guarantee of OBD II compliance. This style connector has been seen on some pre-1996 vehicles which were not OBD II compliant.

OBDII pin out, Signal Assignments - pic attached.

-
Bus positive Line of SAE-J1850
-
Chassis ground
Signal ground
CAN high (ISO 15765-4 and SAE-J2234)
K line of ISO 9141-2 and ISO 14230-4
-
-
Bus negative Line of SAE-J1850
-
-
-
CAN low (ISO 15765-4 and SAE-J2234)
L line of ISO 9141-2 and ISO 14230-4
Battery voltage

Checking which will work.

I have a Santro and i have attached a pic of my obd connector.

mine matches ISO 9141-2 as i have connectors pins 4, 5, 7, 15, and 16.

This way every one can check their ODB pin layout and find out which scanner will work.

Any news on what works with swift?

speed0mania · 26th March 2010, 14:50

The swift has connector pins on 4,5,6,7 and 14,16. What protocol would that be?

COUGAR · 26th March 2010, 17:57

Struggling with this myself. Attached is a shot of the connector on my gypsy (MPFI 2007 model).

It has wires on 4,5, 7 and 16. based on (above) is it 9141-2?

the last attempt to connect a scangauge II did not work. The gauge did not go beyond the "Connecting..." message. Didnt change any settings on the Gauge (refresh settings etc) and connected it as is. The Gauge is otherwise connected to an Emberra and works fine there.

Any help will be appreciated.

Thanks

wmanu · 14th April 2010, 12:34

Experts, can anyone advice which one from these work with Swift Zxi (Mar 2006, Patrol)?

Any one tried OBD scan tools with Swift, so far?

mtnrajdeep · 26th April 2010, 17:47

I have a Swift VDi ABS model (Aug 08) and the connector has additional connections. There are connections for 4,5,6,7 and 14 and 16. I am attaching a snapshot below. Can anyone tell which protocol this connector is for?

GTO · 27th April 2010, 15:17

You guys should probably search within this mega OBD thread. I see the Swift is well covered in that discussion.

Heres an iPhone app that lets you tap into your OBD port with some additional hardware.

DevToaster - Rev - iPhone app development, Great iPhone apps, and more

However, it costs $39.99 !! Plus you have to buy some required hardware.

There is also a FREE "Rev Lite" version, but you'll need to but the interface hardware for that as well!
