TEST
ACTION
APPLICABILITY
1
Turn the ignition on.
With the DRBIII
t, enter Instrument Cluster, System Tests then PCM Monitor.
Does the DRBIII
t display: PCM is active on BUS?
All
Yes
→ Erase the DTC, if DTC resets, measure the resistance of the PCI
Bus circuit between the PCM connector and the ABM connector. If
open, repair as necessary.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 2
2
Turn the ignition on.
With the DRBIII
t, attempt to communicate with the PCM.
Was the DRBIII
t able to communicate with the PCM?
All

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 between the DLC and the PCM
connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Replace and program the Powertrain Control Module in accor-
dance with the Service Information.
Perform BODY VERIFICATION TEST - VER 1.
