Airbag error code can't be cleared but all seems ok
I am the proud owner of a phase 2 GTV 916.
It has the airbag warning light on, so I connected to the Airbag ECU (TRW 60664500) via Multiecuscan using a KKL cable with adapter for pin 3. Originally there were three errors, two related to power supply cut and another is an 0C, open circuit in passenger pretensioner. I cleared the errors but the pretensioner one remains.
Ok, so I removed the passenger (right side, I am in Spain, driver is at the left) seat, disconnected the pretensioner cable and checked. The pretensioner is ok (about 2.2 ohm measured when releasing the shortcircuit clip included in the connector).
So I connected a 2.2 ohm resistor in the cable to the ECU and the error remains and can't be cleared, even after disconnecting the battery for a while.
Then, I removed back seat to gain access to the ECU, located the wires going to the passenger seat and checked the wires from there to the seat. They are ok.
So the only thing that I can think of is a bad ECU or connector to it (although it doesn't seem to have been manipulated). Today I will disconnect the driver's seat pretensioner to check whether at least it shows a new error up and it can'b be cleared afterwards.
