I have got an OBD-II scan tool that is not detecting the OBD-II protocol being used on my 2007 Corolla Altis M/T.
The OBD-II scan tool supports all the five protocols
1. ISO15765-4 (CAN)
2. ISO14230-4 (KWP2000)
4. J1850 VPW
5. J1850 PWM
The pin out of the under dash OBD-II connecter on Altis indicates 2 possible supported protocols.
2. ISO15765-4 (CAN)
I have successfully tested the scan tool on
1. 2003 - Civic VTI – 2003 [ISO9141-2]
2. 2007 - Civic [ISO15765-4 (CAN)]
3. 2006 - Corolla XLI [ISO9141-2]
It will be great if someone can help me figure out the OBD-II protocol supported by Altis. The scan tool is tested OK for both of the possible protocols.
