Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be ORC, INTERROGATE RIGHT
SIACM - STORED.
When Monitored and Set Condition:
ORC, INTERROGATE RIGHT SIACM - STORED
When Monitored: With ignition on, the ORC monitors the PCI Bus for a Right SIACM
status message containing the airbag warning lamp9Lamp On/ OFF9request. The status
message is sent to the ORC once each second or upon any change in the active DTCs.
Set Condition: The Code will set, if the ORC receives an9Lamp On9status message from
the Right SIACM. NOTE: This indicates that there was an active diagnostic trouble code
in the Right SIACM.
ORC, NO RIGHT SIACM MESSAGE - STORED
When Monitored: With ignition on, the ORC monitors the PCI Bus for the Right Side
Impact Airbag Control Module status message. The Right SIACM transmits the status
message to the ORC at 1 - second intervals.
Set Condition: If the ORC fails to see the Right SIACM status message on the PCI Bus
for 10 seconds the code will set.
RIGHT SIACM, NO PCI TRANSMISSION - STORED
When Monitored: With the ignition in the On position and the Right SIACM transmitting
information on the PCI BUS.
Set Condition: The code will set if the Right SIACM cannot detect the Right SIACM
transmitting information on the PCI BUS for 4 consecutive seconds. NOTE: Any PCI Bus
Failure will cause this code to set.
RIGHT SIACM, SEAT SQUIB CIRCUIT OPEN - STORED
When Monitored: With the ignition is On, the Right SIACM monitors the resistance of
the Right Seat Squib circuits.
Set Condition: The Right SIACM has detected an open circuit or high resistance on the
Right Seat Squib circuits.

RIGHT SIACM, SEAT SQUIB CIRCUIT SHORT - STORED
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
the Right Seat Squib circuits.
Set Condition: The Right SIACM has detected a short to ground in the Right Seat Squib
circuits.
POSSIBLE CAUSES
CHECKING FOR ACTIVE RIGHT SIACM 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.
Wiggle the wiring harness and connectors of the Airbag System.
NOTE: Check connectors - Clean and repair as necessary.
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.
Did the DTC become active ?All
Ye s®Select appropriate symptom from Symptom List and continue
with diagnosis.
No®No problem found at this time. NOTE: interrogate the ORC and
Left SIACM for DTCs. Erase all codes in all airbag modules before
returning vehicle to customer.

Symptom:
ORC, NO CLUSTER MESSAGE - ACTIVE
When Monitored and Set Condition:
ORC, NO CLUSTER MESSAGE - ACTIVE
When Monitored: With the ignition in the On position, the ORC monitors the PCI Bus for
a message from the MIC containing the airbag warning lamp status. The MIC transmits
the message one time at ignition on, lamp state change, or in response to the ORC lamp
message.
Set Condition: If the MIC message is not received for 10 consecutive seconds, the code
will set.
POSSIBLE CAUSES
MIC, COMMUNICATION FAILURE
