ORC SYSTEM UNDERVOLTAGE (CONTINUED)
When Monitored and Set Condition
•
When Monitored: Ignition on. The Occupant Restraint Controller (ORC) monitors the Fused Ignition Switch
Output circuit for proper system voltage.
•
Set Condition: If the voltage is below 9.5 volts, the Diagnostic Trouble Code (DTC) is set.
POSSIBLE CAUSES
BATTERY VOLTAGE LOW
FUSED IGNITION SWITCH OUTPUT CIRCUIT HIGH RESISTANCE
OCCUPANT RESTRAINT CONTROLLER
For a complete Restraints System Circuit Diagram, (Refer to 8 - ELECTRICAL/RESTRAINTS - SCHEMATICS AND
DIAGRAMS).
Diagnostic Test
1.
WITH THE DRB III
T
, READ DTCs
Note: When reconnecting the Airbag System components, the
ignition must be turned off and the battery must be disconnected.
Turn the ignition on.
With the DRB III
T
, erase DTCs.
Turn the ignition off.
Turn the ignition on.
Start the engine.
Leave the vehicle running for at least 20 seconds.
With the DRB III
T
, read DTCs.
Does the DRB III
T
display a System Undervoltage DTC?
Yes
>> Go to 2
No
>> The condition that caused this DTC to set is currently not present. Inspect the related wiring harness for
a possible intermittent condition.
2.
MEASURE THE BATTERY VOLTAGE
Start the engine.
Measure the battery voltage with the engine running.
Is the battery voltage below 10 volts?
Yes
>> Refer to the appropriate service information for charging
system testing and repair.
Perform AIRBAG VERIFICATION TEST.
No
>> Go to 3

3.
MEASURE THE VOLTAGE OF THE FUSED IGNITION SWITCH OUTPUT CIRCUIT
WARNING: TURN THE IGNITION OFF, DISCONNECT THE BAT-
TERY AND WAIT TWO MINUTES BEFORE PROCEEDING.
Disconnect the ORC harness connector.
Note: Check connectors - Clean/repair as necessary.
Turn the ignition on.
Measure the voltage of the Fused Ignition Switch Output circuit at the
ORC harness connector.
Is the voltage above 10 volts?
Yes
>> Replace the Occupant Restraint Controller. (Refer to 8 -
ELECTRICAL/RESTRAINTS/OCCUPANT
RESTRAINT
CONTROLLER - REMOVAL).
WARNING: IF THE OCCUPANT RESTRAINT CONTROLLER IS
DROPPED AT ANY TIME, IT MUST BE REPLACED.
Perform AIRBAG VERIFICATION TEST.
No
>> Repair the Fused Ignition Switch Output circuit for high resistance.
Perform AIRBAG VERIFICATION TEST.
