WARNING: This page is about a different car, the 2016 RAM 3500 HD and 2016 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

VERIFY ACTIVE DTC
NOTE:
Make sure the battery is fully charged.
1. Turn the ignition on.
2. With the scan tool, read ORC DTCs.
  Does the scan tool display active B0029-13-RIGHT CURTAIN DEPLOYMENT SQUIB 1 - CIRCUIT OPEN DTC?
  
  Yes
  - Go To 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .

WARNING:
Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Disconnect the Right Side Curtain Airbag harness connector.
  WARNING:
  To avoid serious or fatal injury, do not place an intact undeployed curtain airbag face down on a hard surface, the airbag will propel into the air if accidentally deployed.
  
  NOTE:
  Check connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool Kit (special tool #8443A, SRS Load Tool) and SRS Load Tool Jumper (special tool #8443-1, Jumpers, 2 Pin) to the Right Side Curtain Airbag harness connector.
  WARNING:
  Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
3. With the scan tool, read the ORC DTCs.
  Does the scan tool display active B0029-13-RIGHT CURTAIN DEPLOYMENT SQUIB 1 - CIRCUIT OPEN DTC?
  
  Yes
  - Go To 3
  No
  
  WARNING:
  Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
  - Replace the Right Side Curtain Airbag in accordance with the Service Information.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS-SYSTEM-VERIFICATION-TEST .
CHECK (R2, R4) RIGHT CURTAIN SQUIB 1 CIRCUITS FOR AN OPEN
WARNING:
Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Disconnect the SRS Load Tool Kit (special tool #8443A, SRS Load Tool) and Jumper from the Right Side Curtain Airbag harness connector.
2. Disconnect the ORC harness connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adaptor (special tool #8443-57, Adapter, Supplemental Restraint System Load Tool) to the ORC C2 harness connector.
4. Measure the resistance of the (R4) Right Curtain Squib 1 Line 1 circuit between the Right Side Curtain Airbag harness connector cavity 1 and the SRS Load Tool Adaptor (special tool #8443-57, Adapter, Supplemental Restraint System Load Tool) cavity 14.
5. Measure the resistance of the (R2) Right Curtain Squib 1 Line 2 circuit between the Right Side Curtain Airbag harness connector cavity 2 and the SRS Load Tool Adaptor (special tool #8443-57, Adapter, Supplemental Restraint System Load Tool) cavity 13.
  Is the resistance below 1.0 Ohm on both circuits?
  
  Yes
  
  WARNING:
  If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.
  - Replace the ORC module according to the Service Information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS-SYSTEM-VERIFICATION-TEST .
  No
  - Repair the (R2, R4) Right Curtain Squib 1 circuit for an open.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS-SYSTEM-VERIFICATION-TEST .
