The tcs light and the abs light keep coming on and they come on at the same time

??? .

Possibly by fixing the cause of the check engine light ............No Coke , Pepsi..........No fries , chips............

My abs sensor is broken and has been for years. So, the ABS light goes on and off all the time.

I have a 1999 Transport. The year they changed over to calling it a Montana. We've had this van for a few years now and since then every light on the dash is now on permanently. We brought it into the garage when the engine light first came on, the mechanic couldn't find a problem. Then it happened again and again so, we just chalked it up to age. Then the abs light came on and we had that checked out and it was the same answer. Nothing wrong just the van getting querky. Now I have, I think all the lights lit up on the van . Therefore I am always careful to check oil , and gas, and other fluids regularly... I hope this helps. MCP
