Question about 1999 Jeep Cherokee
No bus means the computer is not talking it has lost commnication with other computers and sensors, the first thing to do is check all your fuses if they are all good then check the battery connection and also the postive cable from battery to fuse/ relay box in engine compartment, make sure they are tight and clean if all is good then you may have a bad computer but i would have a tech diagnose this before just replace the ecm.
