TEST ACTION APPLICABILITY
10 NOTE: Reconnect the PCM/ECM harness connector and the negative bat-
tery cable.
Turn the ignition on.
Measure the voltage of the PCI Bus circuit at the Data Link Connector (DLC).
Is the voltage above 7.0 volts?
All
Yes → Go To 11
No → Test Complete.
11 Turn the ignition off.
Using a voltmeter, connect one end to the PCI Bus circuit at the DLC, and the other
end to ground.
Note: When performing the next step turn the ignition off (wait one minute)
before disconnecting any module. When the module is disconnected turn
the ignition on to check for a short to voltage.
Turn the ignition on.
While monitoring the voltmeter, disconnect each module the vehicle is equipped with
one at a time.
Is the voltage steadily above 7.0 volts with all the modules disconnected?
All
Yes → Repair the PCI Bus circuit for a short to voltage.
Perform BODY VERIFICATION TEST - VER 1.
No → Replace the module that when disconnected the short to voltage
was eliminated.
Perform BODY VERIFICATION TEST - VER 1.
