| What would make the odb2 not work in my 99 Oldsmobile silhouette? |
| If you mean the you cannot get the codes out of the van, then be sure to check the fuses. If the scanner powers up but not read any data, it is either the scanner, a data wire problem in the van, or a bad computer. |
| My scanner is doing same thing with 2001 Oldsmobile Silhouette? do all fuses need to be changed for it to work????? |
| Yes, see answer above. |
