OBD2 Protocol for 2004 Camry

[markw81]

Hi

ive got a 2004 Camry and just purchased an OBD Hand held scanner from my local auto parts shop.  Mainly to scan for codes when the light comes on to save the code read visit to the mechanic.  
 

but the scanner I have doesn’t automatically recognise the codes / protocol and gives me a list to try.  But the list has around 15 different options.  
does anyone know what protocol the 04 Camry uses?   I plug it in, turn the key to number 2 but doesn’t recognise.

2004 is before OBDII was mandated in Australia, so there's a good chance it's still either a proprietary Toyota system (ie Techstream) or J-OBD but using the OBDII style plug.  I know for my 2006 Corolla the scanner connects via ISO 9141-2, but it also auto-detects it so I don't have to choose anything (it just cycles through them one by one until it gets a response ping)

They are obd2 in our region. I have seen the Vident i400AU with Toyota software is capable of reading obd1 Toyotas but you might want to check with these guys from Auscanners.
