TEST
7 Note: Determine which modules this vehicle is equipped with before begin-
ning.
Turn the ignition off.
Disconnect the negative battery cable.
Disconnect the BCM harness connectors and remove the Body Control Module from
the Junction Block.
Measure the resistance between ground and each of the PCI Bus circuits at the BCM
C1, C3, C4 connectors and at the Junction Block Body Control Module connector
cavity 10.
Is the resistance below 1000.0 ohms for any of the measurements?
Yes → Go To 8
No
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 Memory Heated Seat/Mirror Module
was below 1000.0 ohms and is equipped with side airbags, disconnect each
module one at a time.
Measure the resistance between ground and the PCI Bus circuit that previously
measured below 1000.0 ohms.
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.
Is the resistance below 1000.0 ohms with the module disconnected?
Yes → Repair the PCI Bus circuit that resistance measured below 1000.0
No
ACTION
→ Replace the Body Control Module in accordance with the service
information.
Perform BODY VERIFICATION TEST - VER 1.
ohms for a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
→ Replace the module that caused the short to ground on the PCI
Bus circuit.
Perform BODY VERIFICATION TEST - VER 1.
