TEST ACTION APPLICABILITY
6 Turn the ignition off.
Disconnect the negative battery cable.
Using a ohmmeter, connect one end to the PCI Bus circuit at the DLC, and the other
end to ground.
While monitoringthe ohmmeter, disconnect each modulethe vehicle isequipped with
one at a time.
NOTE: Total bus resistance to ground thru all of the modules is typically
between 350 to 1000 ohms. The more modules on the bus, the lower the total
bus resistance will be.
Is the resistance below 150.0 ohms with all the modules disconnected?
All
Yes → Repair the PCI Bus circuit for a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
No → Replace the module that when disconnected the short to ground
was eliminated.
Perform BODY VERIFICATION TEST - VER 1.
