NOTE: Check connectors - Clean and repair as necessary.



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




Does the scan tool display: B1B22-RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT OPEN?

Yes
  • Go to 3


No

3.CHECK (R4) RIGHT CURTAIN SQUIB 1 LINE 1 CIRCUIT FOR AN OPEN



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




NOTE: Check connectors - Clean and repair as necessary.





Is the resistance below 1.0 ohm?

Yes
  • Go To 4


No

4.CHECK (R2) RIGHT CURTAIN SQUIB 1 LINE 2 CIRCUIT FOR AN OPEN





Is the resistance below 1.0 ohm?

Yes
  • Go To 5


No

5.REPLACE THE ORC
