Holden Caprice BCM issue??

[Hzk02]

I have a 2004 Holden Commodore (Caprice 5.7L) Statesman, was switching on the car one day and suddenly the indicators stuck on, horn blaring stuck on, windshield wiper stuck on. I changed my BCM to an Exact used one programmed it then 2 days later happened with the other BCM. What could be my issue? Thank you.

There are no codes, just SRS light but the airbag hasn’t come out.

something wrong with the clockspring is where Id start looking if the srs light is on the must be srs codes?

Was also about to say faulty clock spring.

SRS light/clock spring won't cause the other problems the OP is experiencing.

Common Earth?

Common Earth?

Think your on to it @Fu Manchu , X157 ground bus bar, the one just in behind the battery bolted to the side of the engine bay. It has about 4-5 earths in a plug which is plugged into an earth strap and the earth strap is bolted to the body. Notorious earth for faults like this.

It is the main earthing point for all the issues the OP is having.

Clean this earth point and ALL the earth connections to it and get back to us.
