POSSIBLE CAUSES
CHECKING FOR ACTIVE FRONT CONTROL MODULE DTCS
STORED CODE PRESENT
TEST ACTION APPLICABILITY
1 Turn ignition on.
NOTE: Ensure the battery is fully charged.
Active codes must be resolved before diagnosing stored codes.
With the DRBIIIt, record and erase all DTCs from all modules.
With the DRB III monitor active codes as you work through the system.

The following additional checks may assist you in identifying a possible intermittent
problem:
- Visually inspect related wire harness connectors. Look for broken, bent, pushed out,
spread, corroded, or contaminated terminals.
- Visually inspect related harnesses. Look for chafed, pierced, pinched or partially
broken wire.
- Refer to Wiring Diagrams and Technical Service Bulletins that may apply.

AIRBAG
LEFT SIACM, NO PCI TRANSMISSION - STORED ÐContinued
ORC, WARNING INDICATOR CIRCUIT OPEN - STORED
When Monitored: When the ignition is On, the ORC monitors the PCI Bus for a message
from the MIC containing the airbag warning lamp status Ok or Open. The MIC transmits
the message one time at ignition on, upon lamp state change, or in response to the ORC
lamp message.
Set Condition: The code is set if the lamp state is open for 2 consecutive messages or 2
seconds.
ORC, WARNING INDICATOR CIRCUIT SHORT - STORED
When Monitored: When the ignition is On, the ORC monitors the PCI Bus for a message
from the MIC containing the airbag warning lamp status Ok or Shorted. The MIC
transmits the message one time at ignition on and upon lamp state change.
Set Condition: If the lamp state is Shorted for 2 consecutive messages the code will be set.

When Monitored: When the ignition is on, the Right SIACM monitors the resistance of
the Right Seat Squib circuits.
Set Condition: The Right SIACM has detected that the Right Seat Squib circuits are
shorted together.
RIGHT SIACM, SEAT SQUIB SHORT TO BATTERY - STORED
When Monitored: When the ignition is on, the Right SIACM monitors the voltage of the
Right Seat Squib circuits.
Set Condition: The Right SIACM has detected high voltage on the Right Seat Squib
circuits.
RIGHT SIACM, SEAT SQUIB SHORT TO GROUND - STORED
When Monitored: When the ignition is on, the Right SIACM monitors the resistance of
