If the dashboard mileage light on your 2001 Buick Regal LS is very dim and the Service Vehicle Soon (SVS) light and antilock light stay on, there could be a few potential causes for this issue. Here are some things you can check:
Dim dashboard light: If the dashboard mileage light is very dim, it could be due to a burnt-out bulb or a problem with the dimmer switch. Try turning up the brightness using the dimmer switch, and if that doesn't work, check the bulb and replace it if necessary.
SVS light and antilock light: The SVS light and antilock light staying on could indicate a problem with the car's computer system or with the antilock brake system. It could be caused by a faulty sensor, a wiring issue, or a problem with the computer itself. It's recommended to have the car's computer system scanned for error codes to determine the root cause of the issue.
Battery or charging system: A weak battery or faulty alternator can cause electrical issues in the car, which could be related to the dim dashboard light and the warning lights staying on. Have the battery and charging system checked to rule out this possibility.
I suspect you have low oil pressure from either a worn engine bearing or a defective oil pump. Do not drive this until the oil pressure is checked with a test gauge, you can destroy the engine, about a $3000.00 job to repair..
have a load test done on the battery to check for failing cell. Check the drive belt condition and tension. check alternator out put. Everything you have mentioned indicates a lack of battery power. Check terminal condition and tension of the clamp bolts.
Alternator. Have it tested with a voltmeter while on the car and running. Or take it off and have it tested. The current to run the car and the accessories is from the alternator when the engine is running. The battery light coming on alerts you that the alternator is not doing its job.
You have an engine misfire....unless you have expertise in this area you need to see your local shop as you will damage your catalytic converter if you continue to drive. An OBD II scan tool will id the cylinder to help but knowledge here is key!!
