Cruiser Guy asking for your help.
Any of you Jeep guys help me out? 98 XJ with a "nobus" code showing. Runs fine just has the light on.

has it been "swamped" or rained in ?

i have seen this 3 times , different problem all 3 times .
if it has not had a bath , check the connectors behind the dash cluster.

last one was left in a drainage ditch for 2 days ,(water up to the dash vents)
shorted out the passenger junction/fuse box internally .

you have a communication problem on the main bus (EFI network), like the other guy said, also, a connector under the left side of dash that goes into the firewall and a main junction in the engine bay behind the head
