POSSIBLE CAUSES
INTERMITTENT CONDITION
TEST ACTION APPLICABILITY
1NOTE: For this code to be active, the DRB will not be able to communicate
with any modules on the vehicle (except the PCM).
NOTE: If this code is set and active it will be necessary to perform the PCI
Bus Communication Failure symptom.
WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
NOTE: The conditions that set the DTC are not present at this time. The
following list may help in identifying the intermittent condition.
With the engine running at normal operating temperature, wiggle the wiring
harnesses. This is to try and duplicate the complete bus failure condition.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals.
