When Monitored:
The Occupant Restraint Controller (ORC) continuously communicates with the Right Side Impact Sensor 2
over the sensor signal circuit. The sensor communication and on board diagnostics are powered by the ORC
signal.
•
Set Condition:
This code will set, if the ORC and the Right Side Impact Sensor 2 do not establish and maintain valid data
communications.
Possible Causes
(R18) SIGNAL CIRCUIT SHORTED TO BATTERY
(R18) SIGNAL CIRCUIT SHORTED TO GROUND
(R18, R20) RIGHT SIDE IMPACT SENSOR 2 CIRCUITS SHORTED TOGETHER
(R20) RIGHT SIDE IMPACT SENSOR 2 GROUND CIRCUIT OPEN
(R18) RIGHT SIDE IMPACT SENSOR 2 SIGNAL CIRCUIT OPEN
ORC, RIGHT SIDE IMPACT SENSOR 2
Diagnostic Test
1.
VERIFY ACTIVE B1B76-RIGHT SIDE SATELLITE ACCELERATION SENSOR 2 INTERNAL
Turn the ignition on.
With the scan tool, read ORC DTCs.
NOTE: Ensure the battery is fully charged.
NOTE: When reconnecting Airbag system components, the ignition must be turned off and the battery must
be disconnected.
Does the scan tool display an active: B1B76-RIGHT SIDE SATELLITE ACCELERATION SENSOR 2
INTERNAL?
Yes
>> Go To 2
No
>> Go To 9
2.
CHECK THE (R18, R20) RIGHT SIDE IMPACT SENSOR 2 SIGNAL AND GROUND CIRCUITS FOR A
SHORT TO BATTERY
WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Disconnect the Right Side Impact Sensor 2 connector.
Disconnect the ORC connector.
WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
Measure the voltage of the (R18) Right Side Impact Sensor 2 Signal
circuit and (R20) Sensor Ground circuit at the Right Side Impact Sensor
2 connector and ground.
Is there any voltage present?
Yes
>> Repair the (R18, R20) Right Side Impact Sensor 2 circuits
for a short to battery.
Perform the ORC VERIFICATION TEST - VER 1.
No
>> Go To 3

3.
CHECK THE (R18) RIGHT SIDE IMPACT SENSOR 2 SIGNAL CIRCUIT FOR A SHORT TO GROUND
Measure the resistance of the (R18) Right Side Impact Sensor 2 Signal
circuit between the Right Side Impact Sensor 2 connector and ground.
Is the resistance below 100K ohms?
Yes
>> Repair the (R18) Right Side Impact Sensor 2 Signal circuit
for a short to ground.
Perform the ORC VERIFICATION TEST - VER 1.
No
>> Go To 4
4.
CHECK THE (R18, R20) RIGHT SIDE IMPACT SENSOR 2 CIRCUITS FOR A SHORT TOGETHER
Measure the resistance between the (R18) Right Side Impact Sensor 2
Signal and (R20) Sensor Ground circuits at the Right Side Impact Sen-
sor 2 connector.
Is the resistance below 100K ohms?
Yes
>> Repair the (R18, R20) Right Side Impact Sensor 2 circuits
shorted together.
Perform the ORC VERIFICATION TEST - VER 1.
No
>> Go To 5

5.
CHECK THE (R18) RIGHT SIDE IMPACT SENSOR 2 GROUND CIRCUIT FOR AN OPEN OR HIGH
RESISTANCE
Connect the 8443 Load Tool ORC Adaptor to the Occupant Restraint
Controller C2 connector.
Measure the resistance of the (R20) Right Side Impact Sensor 2
Ground circuit between the Right Side Impact Sensor 2 connector and
the 8443 Load Tool ORC Adaptor.
Is the resistance below 1 ohm?
Yes
>> Go To 6
No
>> Repair the (R20) Right Side Impact Sensor 2 Ground circuit
for an open or high resistance.
Perform the ORC VERIFICATION TEST - VER 1.
6.
CHECK THE (R18) RIGHT SIDE IMPACT SENSOR 2 CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
Measure the resistance of the (R18) Right Side Impact Sensor 2 Signal
circuit between the Right Side Impact Sensor 2 connector and the 8443
Load Tool ORC Adaptor.
Is the resistance below 1 ohm?
Yes
>> Go To 7
No
>> Repair the (R18) Right Side Impact Sensor 2 Signal circuit
for an open or high resistance.
Perform the ORC VERIFICATION TEST - VER 1.
