1
Note: Determine which modules this vehicle is equipped with before begin-
ning.
Note: When attempting to communicate with any of the modules on this
vehicle, the DRB will display 1 of 2 different communication errors: a NO
RESPONSE message or a BUS +/- SIGNALS OPEN message.
Turn the ignition on.
Using the DRB, attempt to communicate with the following control modules:
Body Control Module (BCM)
Instrument Cluster (MIC)
Airbag Control Module
Controller Antilock Brake (CAB)
Was the DRB able to communicate with one or more Module(s)?
All
Yes
→ Go To 2
No
→ Go To 3
2
Turn the ignition off.
Note: Visually inspect the related wiring harness. Look for any chafed,
pierced, pinched, or partially broken wires.
Note: Visually inspect the related wire harness connectors. Look for broken,
bent, pushed out, or corroded terminals.
Note: If the DRB can not communicate with a single module, refer to the
category list for the related symptom.
Were any problems found?
All
Yes
→ Repair wiring harness/connectors as necessary.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Test Complete.

Turn the ignition off.
Disconnect the BCM C2 harness connector.
Disconnect the DRB from the Data Link Connector (DLC).
Measure the resistance of the PCI Bus circuit between the Data Link Connector
(DLC) and the BCM C2 connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 4
No
→ Repair the PCI Bus circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
4
NOTE: Reconnect the BCM C2 harness connector.
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 5
No
→ Go To 7
5
Note: Determine which modules this vehicle is equipped with before begin-
ning.
Turn the ignition off.
Disconnect the BCM C2 and C3 harness connectors.
Turn the ignition on.
Measure the voltage of each PCI Bus circuit at the BCM C2 and C3 connectors.
Is the voltage steadily above 7.0 volts for any measurement?
All
Yes
→ Go To 6
No
→ Replace the Body Control Module in accordance with the service
information.
Perform BODY VERIFICATION TEST - VER 1.
6
Turn the ignition off.
Disconnect the module that corresponds to the PCI Bus circuit that measured
steadily above 7.0 volts.
Turn the ignition on.
NOTE: If the PCI Bus circuit for the Radio was above 7.0 volts and is
equipped with a CD Changer, disconnect the CD Changer before the Radio.
NOTE: If the PCI Bus circuit for the Instrument Cluster (MIC) was above 7.0
volts and is equipped with a Compass/Mini Trip Computer (CMTC), discon-
nect the CMTC before the MIC.
Measure the voltage of the PCI Bus circuit that previously measured above 7.0 volts.
Is the voltage steadily above 7.0 volts with the module disconnected?
All
Yes
→ Repair the PCI Bus circuit that measured over 7.0 volts for a
short to voltage.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Replace the module that caused the short to voltage on the PCI
Bus circuit.
Perform BODY VERIFICATION TEST - VER 1.

Note: Determine which modules this vehicle is equipped with before begin-
ning.
Turn the ignition off.
Disconnect the negative battery cable.
Disconnect the BCM C2 and C3 harness connectors.
Measure the resistance between ground and each of the PCI Bus circuits at the BCM
C2 and C3 connectors.
Is the resistance below 1000.0 ohms for any of the measurements?
All
Yes
→ Go To 8
No
→ Replace the Body Control Module in accordance with the service
information.
Perform BODY VERIFICATION TEST - VER 1.
8
Turn the ignition off.
Disconnect the negative battery cable.
Disconnect the module that corresponds to the PCI Bus circuit that resistance
measured below 1000.0 ohms.
NOTE: If the PCI Bus circuit for the Radio was below 1000.0 ohms and is
equipped with a CD Changer, disconnect the CD Changer before the Radio.
NOTE: If the PCI Bus circuit for the Instrument Cluster (MIC) was below
1000.0 ohms and is equipped with a Compass/Mini Trip Computer (CMTC),
disconnect the CMTC before the MIC.
Measure the resistance between ground and the PCI Bus circuit that previously
measured below 1000.0 ohms.
Is the resistance below 1000.0 ohms with the module disconnected?
All
Yes
→ Repair the PCI Bus circuit that resistance measured below 1000.0
ohms for a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Replace the module that caused the short to ground on the PCI
Bus circuit.
Perform BODY VERIFICATION TEST - VER 1.
