Just connected the SIR3.. and flashing codes are for a "wiring issue" ( as you suggested ) .... so , will need to check all the wiring coming from /to the SRS module to check for some shortcut ( or open circuit ) "somewhere"....
What i do not understand is that from the X74 connector there are no issues to the diagnostic connector at the hood...
- pin 6 at X74 (RxD) - to pin 15 of the diagnostic head ( worked )
- pin 7 at X74 (TxD) - to pin 20 of the diagnostic head. ( worked )
so, what should i check and where ?
Will update...
