Diagnostic Test

DETERMINE ACTIVE OR STORED DTC
NOTE:
Make sure that the battery is fully charged.

NOTE:
The scan tool, SRS Load Tool Kit (special tool #8443A, SRS Load Tool), and DVOM are required to perform the following test.
1. Turn the ignition on.
  Select ACTIVE or STORED DTC:
  
  ACTIVE DTC
  - Go To 2
  STORED DTC
  - Go To 5

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 Left Side Curtain Airbag connector.
  WARNING:
  Do not place an intact non-deployed curtain airbag face down on a hard surface, the airbag will propel into the air if accidentally deployed. Failure to follow these instructions may result in possible serious or fatal injury.
  
  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 #8443-8, Jumper, SRS Load) to the Left Side Curtain Airbag 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 active ORC DTCs.
  Does the scan tool display: B1B1A-LEFT SIDE CURTAIN SQUIB 1 CIRCUIT OPEN?
  
  Yes
  - Go To 3
  No
  - Replace the Left Side Curtain Airbag in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE - AIRBAG SYSTEM VERIFICATION 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 SRS Load Tool Kit (special tool #8443A, SRS Load Tool) and SRS Load Tool Jumper (special tool #8443-8, Jumper, SRS Load) from the Left Side Curtain Airbag connector.
2. Disconnect the ORC connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) to the ORC connectors.
4. Measure the resistance of the (R3) Left Curtain Squib 1 Line 1 circuit between the Left Side Curtain Airbag connector cavity 2 and the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) cavity 32-9.
  Is the resistance below 1.0 Ohm?
  
  Yes
  - Go To 4
  No
  - Repair the (R3) Left Curtain Squib 1 Line 1 circuit for an open.
  - Perform AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE - AIRBAG SYSTEM VERIFICATION TEST .
CHECK THE (R1) LEFT CURTAIN SQUIB 1 LINE 2 CIRCUIT FOR AN OPEN

1. Measure the resistance of the (R1) Left Curtain Squib 1 Line 2 circuit between the Left Side Curtain Airbag connector cavity 1 and the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) cavity 32-10.
  Is the resistance below 1.0 Ohm?
  
  Yes
  
  WARNING:
  If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.
  - Replace the ORC in accordance with Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE - AIRBAG SYSTEM VERIFICATION TEST .
  No
  - Repair the (R1) Left Curtain Squib 1 Line 2 circuit for an open.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE - AIRBAG SYSTEM VERIFICATION TEST .
CHECKING STORED OR INTERMITTENT CODES
NOTE:
Diagnose and repair all active codes before diagnosing stored codes.
1. With the scan tool, record and erase all Airbag System Module DTCs.
  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.
2. Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chafed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.
3. Reconnect all disconnected components and harness connectors.
  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.
4. With the scan tool, monitor for active codes while performing the following:
5. In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question / causing the intermittent condition.
  Are any ACTIVE DTCs present?
  
  Yes
  - Select the appropriate diagnostic procedur. Refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX
  No
  - No problem found at this time. Erase all codes before returning the vehicle to the customer.
