996 Turbo ABS and PSM warning - battery?


Recommended Posts

Hi guys,


My 2001 996 Turbo (ROW) has not been used a great deal over the hot summer we have here in Dubai. Went to start it the other day and the ignition turnover sounded a little weak. Went for a 30 min drive and parked up. Ten mins later I went to restart the car and got the two warnings - ABS and PSM. Suspected the battery straight away so checked it with a multimeter. It's reading 12.1 at rest which is very low. So, I need a new battery.


Just to be sure I took the battery out of the 996 and thought I'd start the car with the brand new battery I'd just bought for my Subaru BRZ, which is a lower spec battery.  Car started fine but the ABS and PSM warnings remain. I didn't drive the car, just started it on the driveway.


Will these warnings need to be reset or should they go away after a while with a new 996 turbo spec battery? I realise it could just be a coincidence and I have another issue relating to the warning in addition to my weak battery.


Any thoughts welcome!

Thanks, but my alternator was replaced less than 3k miles ago. Sorry, should've said!


Doesn't matter if it was changed 3 miles ago, it still needs to be tested.  A lot of problems like this are traced to the alternator rather than the battery.
