Turn the ignition off.
Disconnect the PCM harness connectors.
Disconnect the BCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the PCI Bus circuit from the BCM harness connector to the
appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes
→ Replace BCM in accordance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
No
→ Repair the PCI Bus circuit between the PCM and the BCM for an
open.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
