Camry 2003 ACV36R OBD2 connector problem.

[achris]

Hello,

I'm new here, but not new to forums. I'm in Perth (southern suburbs) and this is my wife's car. I have just taken on the servicing as it's now out of the extended warranty we bought it with.

I have an OBD2 connector (using ELM327) with USB connectivity and a laptop

I am having a problem getting connected to this vehicle. I wasn't sure if it was the car or my connector, so I checked it with my mothers' 2003 Mazda 6 and with works perfectly with all software packages supplied with the tool.

I am wondering if anybody else has a 2003 and are having problems connecting...or if any body can tell me what protocol and pins this vehicle uses...

Many thanks for you help....

Chris......

australia only made OBDII ports a requirement from 2007. some of these pre-2007 seem to be OBDII compliant but in fact they are not. My 2003 corolla isn't OBDII compatible even though the port is shaped like one. i narrowed the type of port down to 2 types... ISO and i forgot the other one. but yeah its a PITA.

Thanks for that... The port even says "OBDII" on the cover... Any idea what works, and how I read this sucker?

It's an earlier OBDII system so chances are your handheld doesn't have the data chip required. I've had 3 different OBDII scanners plugged in mine and none of them work.

A workshop OBDII reader however (those damn expensive ones you wouldn't bother buying for home use) will read it no problem.

Thanks for that Gordon. Not going to invest in a 'damned expensive reader'... At least I know it's not me...

Cheers...
