Anybody have symptoms of ABS/DSC/BRAKE trifecta lights on the dash?


Symptoms are:


heavy steering as if its always in M Mode.



oil temperature gauge jumping around on dash.


car starts but seems to be a "weak start" .

having slight idle fluctuations when stationary.



Could a VR be the cause of (some) of these symptoms ?

Yeah, especially the jumpy gauges. I wouldn't wait - usually when the VR fails it oversupplies voltage, so it can toast much more expensive modules. In my case it was a rapid decline and it ended up with the car stalling a block from home (thankfully). You can buy the valeo part (same company that supplies the OEM alternator) for less than $50.

The thing is im not getting over supplied voltage. Im not getting any voltage from the alternator. Could the IBS be responsible for this or failed alternator ?



in other words im getting the same 12.2-12.5 volts from the battery - does not matter if the car is running or not. Eventually battery dies out.

I just want to say Thank You to the OP for taking his time to write up this DIY.

I tackled this DIY yesterday and my beast is running well again.


A few stuff I want to add:

Watch this YouTube video on how the brushes on the voltage regulator makes contact on the slip ring.

I know some of you guys are still having problems after replacing the VR. My guess is, the slip ring of your alternator is dirty and its not making a good contact with the brushes of the new VR.
I cleaned the slip ring of my alternator with some strips of sandpaper to make sure it will have a good contact with the brushes of the new VR.

Also, to remove the plug, its alot easier with a pry tool. With your left hand, reach the plug through the top of the alternator and push the down the tab with your thumb. With a pry tool on your other hand, gently pry the plug away from the alternator. You'll be amazed on how easy it was.

Here are some picture of my install:

Old Voltage Regulator:


Old vs New Regulator:


New Regulator only has one prong and the old one has two prongs. No worries, the plug only has one wire.



The brushes is being held by the round plastic cup. They will release once you push the round plastic cup in.



Round Plastic Cup - you need to push this in after you securely screwed in the VR to the alternator so the brushes releases to the slip ring.



Picture of the Slip Ring:



Cleaned Slip Ring:



If you guys have any question. HMU, I might be able to help or answer your question.


Good Luck....
