: Speed limit setting on 98 STS

09-09-04, 05:39 AM
Hi All,

I am from england and have a 1998/99 model STS. I have had the car for four months and it is a cracking car. Yesterday morning I started the car and the computer bonged at me and the read out stated : Speed Limit set 90mph

I had done nothing to set this and it has never come up before.
I've had the car over 90 before and am worried that this maybe in place if the car is experiencing a problem that I don't know about.

Can anyone offer advise of what the problem may be or if it a computer error?

Kind Regards

There will be one or more Diagnostic Trouble Code (DTC) set on your system. Read the codes, write them down, clear them to start fresh and see if they return.

Speed can be limited when the suspension is reporting problems and setting DTCs.

And sometimes, DTCs are reported in error.

Yep, there is some sort of suspension or chassis trouble code that is setting causing the speed limit of 90 to set.
