One of my neighbourhood have Vectra-C from 2004.
On display occur the Service indicator.
After diagnose the entire car, result the next error codes:
B0670 - Airbag Telltale Circuit Malfunction - that means the LED of Airbag don't turn on
P0650 - Malfunction Indicator Lamp (MIL) Control Circuit Malfunction - that means the LED of Check Engine don't turn on
OK, I bring out the instrument panel and make tests and measurements.
On the connector from instrument panel exist two wires, on pins 6 and 12 which must power these LED's. But from where ? and How ? I don't know !
If somebody have the explanation of this connector, I ask for Help.
If somebody knows where go the cable from the instrument panel, I ask for Help.
If somebody have it in the past this problem, I ask also for Help.
If somebody have ideas, comments, suggestions, please write to me.
The connector from the instrument panel have 12 pins:
1 2 3 4 5 6
7 8 9 10 11 12
These: 2,3,7,9 and 10 are unused and 1,4,5,6,8,11 and 12 are used.
Also, in this connector, join the next wire colors: red, yellow-brown, black,green, green,yellow-grey, brown.
As I said, pins no. 6 and 12 have something to do with LED of Airbag and LED of MIL.
For sure, I have one +12V, one Ground, one CAN-L and CAN-H, the two suspect wire :6 and 12 and also one unnamed wire.
I waiting your messages.
