Hi... again!

My car has done something odd twice in the last 24 hrs.

Kicking up a steep hill with a nice 70deg corner halfway up (my road to my house) I was going about 80kph (45-ish(?) MPH).. I was about 2/3rds of the way through the turn when I noticed the usual lights that normally come on when you first start the car came on; Air bag, battery..

Freaked me out proper... but nothing seemed to come of it. No lag in power or anything... just odd.

Today, I was givin 'er around another corner, this one down a steep hill and about 45 to 50 degree turn at the bottom... when the Passkey idiot light came on... and stayed on. When I got home, I turned off the vehicle... and restarted it. No more light. Took it for a run (Not too fast or anything..) and no problems.

Looking for any info on what this might be. Almost inclined to think it is a loose connection of some kind because of the g-forces and jostling involved in cornering when it happens.

Most internet searches indicate a possible bad BCM... but I cannot find a whole lot of info about diagnosing and testing this.

The other one that pops up is a bad battery. That might be... as it is stock, but has never given me any trouble. Any one with ideas about this?

Thank you!

Craig

I would check all engine/body grounds first. Followed by replacing your battery if you have doubts on it's health. Then if it keeps happening, you know it's something else.

Also check your battery cables for corrosion and make sure their on snug.
