red and black leads and the cable to probe adapter to the scope input cable.
With the DRBIII
t select Pep Module Tools.
Select lab scope.
Select Live Data.
Select 12 volt square wave.
Press F2 for Scope.
Press F2 and use the down arrow to set voltage range to 20 volts. Set Probe to x10.
Press F2 again when complete.
Connect the Black lead to the chassis ground. Connect the Red lead to the PCI Bus
circuit in the Power Liftgate Module C2 connector.
Turn the ignition on.
Observe the voltage display on the DRB Lab Scope.
Does the voltage pulse from 0 to approximately 7.5 volts?
All
Yes
→ Go To 4
No
→ Repair the PCI Bus circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.

TEST
ACTION
APPLICABILITY
1
Turn the ignition on.
Note: As soon as one or more module communicates with the DRB, answer
the question.
With the DRB, attempt to communicate with the Airbag Control Module (ACM).
With the DRB, attempt to communicate with the Body Control Module (BCM).
Was the DRB able to I/D or establish communications with either of the modules?
All
Yes
→ Go To 2
No
→ Refer to the Communications category and perform the symptom
PCI Bus Communication Failure.
Perform BODY VERIFICATION TEST - VER 1.
2
Turn the ignition off.
