possible fix needed Lw300

[Tuneup]

start car self diagnostics seem ok for traction control after a couple of seconds the the on/off switch light goes out -- traction control is off and cannot be turn on -- computer reset works only once and then an engine restart repeats the problem

I had that happen with my '01 lw300 also once.
Pull the 'controls B+' fuse in the under hood fuse box for about 10 seconds. This will reset any codes and faults. I did this and the fault never came back. See if it will work for you. If it comes back you'll have to troubleshoot the ABS or Body control module.
