TEST ACTION APPLICABILITY
1 Turn the ignition on.
With the DRBIIIt in Body Computer, record and erase BCM DTCs.
Cycle the ignition from ON to OFF.
Start the engine.
With the DRBIIIt in Body Computer, read BCM DTCs.
Does the DRBIIIt display: IOD OUTPUT CIRCUIT SHORT TO GROUND?
All
Yes → Go To 2
No → The condition that caused this DTC is currently not present. Use
the wiring diagram/schematic as a guide, and inspect the related
wiring harness for a possible intermittent condition.
Perform BODY VERIFICATION TEST - VER 1.
2 NOTE: The following modules are on the IOD-B(+) circuit: RKE Module,
Instrument Cluster and both Door Window Motors (for hall effect supply).
Disconnect each of the modules or components listed above, one at a time while
observing the DRBIIIt until either the DTC is no longer present or all of the modules
and components are disconnected.
Ensure the RKE Module, Instrument Cluster and both Door Window Motors are
disconnected before proceeding.
With the DRBIIIt in Body Computer, erase BCM DTCs.
Cycle the ignition from ON to OFF to ON.
With the DRBIIIt in Body Computer, read BCM DTCs.
Does the DRBIIIt display: IOD OUTPUT SHORT?
All
Yes → Go To 3
No → Replace the module or the component that when disconnected,
allowed the DTC to clear.
Perform BODY VERIFICATION TEST - VER 1.
