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.
POSSIBLE CAUSES
CHECKING FOR ACTIVE ORC DTC'S
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 and rotate the
steering wheel from stop to stop.
NOTE: Check connectors - Clean and repair as necessary.
You have just attempted to simulate the condition that initially set the trouble code
message.
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. Erase codes in all modules before
returning vehicle to customer.
