Srs Flashing Light And Dtc 72-Diagnostic Port? 2003 Rx

[dscottp]

Hello all,

I have an SRS light that flashes about once per second. I found info on reading the codes by shorting OBDII pins together and obtained a 72 which refers to the drivers side tensioner or sensor, My plan was to clear the codes to see if they go away or return. This can be done using pins TC and AB of the OBDII connector but the connector inside my 2003 RX has it.

Has anyone seen this under hood connector? Am I looking in the right place? I searched all over.

Any SRS experience to be shared would be good!

Thanks in advance
