NO RIGHT SIDE IMPACT SENSOR 1 COMMUNICATION (CONTINUED)

For the Airbag System circuit diagram (Refer to 8 - ELECTRICAL/RESTRAINTS - SCHEMATICS AND DIAGRAMS).

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
The Occupant Restraint Controller (ORC) continuously communicates with the Right Side Impact Sensor 1
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 1 do not establish and maintain valid data
communications.

Possible Causes

(R14) RIGHT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT SHORTED TO BATTERY

(R14) RIGHT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT SHORTED TO GROUND

(R14, R16) RIGHT SIDE IMPACT SENSOR 1 CIRCUITS SHORTED TOGETHER

(R16) RIGHT SIDE IMPACT SENSOR 1 GROUND CIRCUIT OPEN

(R14) RIGHT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT OPEN

ORC, RIGHT SIDE IMPACT SENSOR 1

Diagnostic Test

1.

VERIFY THAT DTC NO RIGHT SIDE IMPACT SENSOR 1 COMMUNICATION

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.
Turn the ignition on.

With the scan tool, read ORC DTCs.

Does the scan tool display active: No Right Side impact Sensor 1 Communication?

Yes

>> Go To 2

No

>> Go To 9

2.

CHECK THE (R14, R16) RIGHT SIDE IMPACT SENSOR 1 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 1 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 (R14) Right Side Impact Sensor 1 Signal
circuit and (R16) Right Side Impact Sensor 1 Ground circuit at the
Right Side Impact Sensor 1 connector and ground.

Is there any voltage present?

Yes

>> Repair the (R14, R16) Right Side Impact Sensor 1 circuits

for a short to battery.

Perform the ORC VERIFICATION TEST - VER 1.

No

>> Go To 3

3.

CHECK THE (R14) RIGHT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT FOR A SHORT TO GROUND

WARNING: To avoid personal injury or death, turn ignition on,
then reconnect the battery.
Measure the resistance of the (R14) Right Side Impact Sensor 1 Sig-
nal circuit between the Right Side Impact Sensor 1 connector and
ground.

Is the resistance below 100K ohms?

Yes

>> Repair the (R14) Right Side Impact Sensor 1 Signal circuit

for a short to ground.

Perform the ORC VERIFICATION TEST - VER 1.

No

>> Go To 4

4.

CHECK THE (R14, R16) RIGHT SIDE IMPACT SENSOR CIRCUITS FOR A SHORT TOGETHER

Measure the resistance between the (R14) Right Side Impact Sensor
1 Signal circuit and (R16) Right Side Impact Sensor 1 Ground circuit
at the Right Side Impact Sensor 1 connector.

Is the resistance below 100K ohms?

Yes

>> Repair the (R14, R16) Right Side Impact Sensor 1 circuits

shorted together.

Perform the ORC VERIFICATION TEST - VER 1.

No

>> Go To 5

5.

CHECK THE (R16) RIGHT SIDE IMPACT SENSOR 1 GROUND CIRCUIT FOR AN OPEN OR HIGH
RESISTANCE

Connect the 8443 Load Tool ORC Adaptor to the Occupant Control
Module connector.

Measure the resistance of the (R16) Right Side Impact Sensor 1
Ground circuit between the Right Side Impact Sensor 1 connector and
the 8443 Load Tool ORC Adaptor.

Is the resistance below 1 ohm?

Yes

>> Go To 6

No

>> Repair the (R16) Right Side Impact Sensor 1 Ground cir-

cuit for an open or high resistance.

Perform the ORC VERIFICATION TEST - VER 1.
