Nice work may be your device can establish a link with my cars OBDII, so far no scanner been able to. I bought a Trip Computer from UK, still no luck had to sell that great piece of Hardware.

Thumbs up

(Please next time use a better music, it sounded like Altaf Raja's Tum to thray pardesi)

if it is working with 2006 vitz then it must work with 2004 vitz, so ur CHECK Engine Light is ON ?? & u r running ur vitz on CNG ?? if the check engine light goes off after u switch to Petrol then its normal man nothing to worry about,

when EFI Engine is fortified with fumigation type CNG Kit (CNG Ventury in Air intake path) it mislay its foremost control on A/F mixing ratio as Fuel injectors r disengaged by the emulator by adding some dummy pack across it & Advancer is sitting there to cheat the ECU by adding some extra biasing voltage to the MAP/MAF/AFM signal lines in order to advance the ignition time, as the A/F mixing ratio Process is running in closed loop ECU gives up & glow the Check Engine Light, Thumbs up for sequential injection CNG kit but its too expensive nah

No its on petrol, no CNG for any of our wheels. Right now there are no engine check lights, but the thing is I like to keep a track of things and when I drive my favorite car I want to keep an eye on things, for which I bought Car Trip Computer. Problem is neither that or any other scanner can link with my car.

I have a JDM toyota vitz 2002 model with an 16 pin OBD 2 scanner port. I recently purchased launch creader V scan tool from china( http://www.automotive-diagnostic-tools.com/Launch-Creader-V-OBDII-Auto-Scanner-p/lau-301050049.htm). However , it is not reading ecu of the car and giving communication error.The same scanner worked perfectly on all honda cars.All wires of OBD 2 connector are fine and unswitched 12 V are present at pin 16.Any productive help will be appreciated.
