U0175-LOST COMMUNICATION W/RIGHT SIDE SATELLITE ACCELERATION SENSOR 1





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) SIGNAL CIRCUIT SHORTED TO BATTERY
  
(R14) 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 U0175-LOST COMMUNICATION W/RIGHT SIDE SATELLITE ACCELERATION SENSOR 1

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 active: U0175-LOST COMMUNICATION W/RIGHT SIDE SATELLITE ACCELERATION SENSOR 1?

Yes
  • Go To 2


No
  • Go To 9

2.CHECK THE (R14) and (R16) RIGHT SIDE IMPACT SENSOR 1 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.





WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.




Is there any voltage present?

Yes
  • Repair the (R14) and (R16) Right Side Impact Sensor 1 circuits for a short to battery.
  • Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1.


No
  • Go To 3

3.CHECK THE (R14) and (R16) RIGHT SIDE IMPACT SENSOR 1 CIRCUITS FOR A SHORT TO GROUND



WARNING: To avoid personal injury or death, turn ignition on, then reconnect the battery.





Is the resistance below 100K ohms on either circuit?

Yes
  • Repair the (R14) Right Side Impact Sensor 1 Signal or (R16) Right Side Impact Sensor 1 Ground circuit for a short to ground.
  • Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1.


No
  • Go To 4

4.CHECK THE (R14) and (R16) RIGHT SIDE IMPACT SENSOR CIRCUITS FOR A SHORT TOGETHER





Is the resistance below 100K ohms?

Yes
  • Repair the (R14) and (R16) Right Side Impact Sensor 1 circuits shorted together.
  • Perform the *AIRBAG SYSTEM 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





Is the resistance below 1 ohm?

Yes
  • Go To 6


No
  • Repair the (R16) Right Side Impact Sensor 1 Ground circuit for an open or high resistance.
  • Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

6.CHECK THE (R14) RIGHT SIDE IMPACT SENSOR 1 CIRCUIT FOR AN OPEN OR HIGH RESISTANCE





Is the resistance below 1 ohm?

Yes
  • Go To 7


No
  • Repair the (R14) Right Side Impact Sensor 1 Signal circuit for an open or high resistance.
  • Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

7.CHECK OPERATION OF THE RIGHT SIDE IMPACT SENSOR 1




WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.







Did the active Right Side Impact Sensor 1 DTC return?

Yes
  • Go To 8


No
  • Repair is complete.
  • Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

8.REPLACE THE OCCUPANT RESTRAINT CONTROLLER

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.


WARNING: If the airbag control module is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment and personal injury or death.



If there are no possible causes remaining, view repair.

Repair
  • Replace the Occupant Restraint Controller in accordance with Service Instructions.
  • Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

9.TEST FOR AN INTERMITTENT CONDITION



WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.






WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.



WARNING: To avoid personal injury or death, maintain a safe distance from all airbags while performing the following steps.







Are any ACTIVE DTCs present?

Yes
  • Select the appropriate symptom from Symptom List.


No
  • No problem found at this time. Erase all codes before returning vehicle to customer.
