[msienicki]

I have problem with Vectra 07 1.6. wont start at morning. when I clear fault few times and try to crank few times is working.
at the morning I had this faults:
ecu:
P1600 - Replace Electronic Control Unit (ECU)
(35) - Present
airbag :
U2139 - Invalid Data from CIM (Steering Column Module)
(7F) - Not present
bcm:
B3901 - Wrong Environment Identifier Received

Every morning is this same.
This is ecu problem or some of connector has bad connection. Somebody had this same problem?

Hi

B3901 - Wrong Environment Identifier Received
(00) - Not present

This fault can also be caused by faulty key...........So if you have other key try that.

or bad connection on the cim.

Did you check the battery, an old battery will cause also this kind of problems. Just fit a new battery and check what happens .
