hgt cant connect to airbag ecu with mes and cable

i can connect to the same ecu with same cable when fitted to other hgt

cleaned that earth near airbag ecu and its still same
can connect to engine ecu, body, dash...

airbag lights come on normally when i turn key and then both go off
quite strange

Hmmmm odd...
Unless the ecu isnt working at all?
Cant be power issue otherwise dash light would be on....

Looks like a comms issue from obd port to airbag ecu - might worth checking that with a wiring diagram
 
ecu works cuz i hooked it up to another hgt
a mystery

No mystery, just no connection between ECU and EOBD socket (or possibly a short circuit).
Get out the schematic and ohmmeter.


Yup sounds just like a missing connection/broken connection between the OBD socket and the ECU

Haynes dont even look at airbag system.... probably for a good reason
Autodata?
