HI
First time posting here. I recently got new battery installed in my Lexus LS460.
Car was running fine until this morning.
all of sudden display showed the error PCS and VSC and ABS Sign. I turn off the engin. Turned ON again,errors were there and car was running very slow.
Temperature dropped this morning after snow fall. Could this change in weather created any problem.
Any idea what might have went wrong.
Please advice.

 

Any help please,

 

First thing I would check is the connections. Make sure they are very tight and the posts are clean. If they are, try to find a place to test the battery and make sure it is good. I know its new, but you never know.

 

Those warning lights are probably the results of the manner in which your new battery was installed - it was probably installed while the IGNITION was ON. By that I don't mean that the engine was running at the time of installation but the IGNITION was probably ON. It is very common for the ignition to be left on when batteries fail or become fully discharged because of events related to trying to start the car. I can try to explain that again if anyone is interested, but for you, you are probably most interested in how to move on.

So, turn you car's IGNITION OFF. Disconnect the battery by removing the battery-cable from the NEGATIVE terminal of the battery for a few minutes. Reconnect the battery. Start your car normally and allow the electronics to initialize - takes about a minute. If the warning lights are still on after that you will have to get them reset through the car's OBDII port.

 

I have removed the battery again and stalled after few hours. After system reset again, there is no error light. I am parked inside the garage. I suspect when will drive out on the which still have some snow on it, error will show again. Will update.

Some of the lights related to Vehicle Stability Control are latched when those systems sense instability and do not reset until the ignition is cycled. Driving on ice or snow or wet roads may invoke some of these warning.
