I have a 2001 Cherokee sport that is showing no bus after sitting for a few years. None of the gauges work, and the cluster shows NO BUS, airbag light, and check engine light. I checked the voltage on the 3 to 4/5 and the 11 to 4/5 and both are around 2.5v. The cluster self test with holding the pin on the cluster its self, passes with everything working. I am wondering if the cluster its self still may be bad?
