Okay, I attached the description and the checks that need to be done.
Do you have a scan tool that can read the Airbag system?

Theory of Operation
When powered, the Occupant Restraint Controller (ORC) sends a test current to the squibs to verify the integrity of the squib and wiring. These circuits are maintained in a "floating" configuration at the ORC (connected to neither power nor ground) as protection against inadvertent deployment. Use of the Supplemental Restraints System (SRS) Load Tool Kit (8443A) in the tests below substitutes a suspect squib with a known good component. The use of the SRS Load Tool Adapter provides a test point as well as a method for opening the shorting bar connections within the ORC harness connector.
- When Monitored:
The ORC sends out a 40 mA diagnostic current on each squib voltage supply circuit at power up and every 100 ms thereafter while the ignition is on.
- Set Condition:
This Diagnostic Trouble Code (DTC) sets when the ORC detects a short to ground on the squib circuit for more than 2.5 seconds. This DTC transitions from active to stored when the ORC sees a recovery from a short to ground condition for greater than 2.5 seconds.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. See: Restraints and Safety Systems > Initial Inspection and Diagnostic Overview > Restraint System Pre-Diagnostic Procedure.
Diagnostic Test
1. 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 B0010-11-PASSENGER FRONTAL SQUIB 1 CONTROL - CIRCUIT SHORT TO GROUND DTC?
Yes
Go To 2
No
Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. See: Restraints and Safety Systems > Initial Inspection and Diagnostic Overview > Restraint System Intermittent Condition Test.
2. CHECK PASSENGER AIRBAG SQUIB FOR SHORT TO GROUND

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 Passenger Airbag Squib harness connectors.
WARNING:
Do not place an intact non-deployed airbag face down on a hard surface, the airbag propels 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 (8443A) and SRS Load Tool Jumper (8443-8) to the Passenger Airbag Squib 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.
3. With the scan tool, read the ORC DTCs.
Does the scan tool display active B0010-11-PASSENGER FRONTAL SQUIB 1 CONTROL - CIRCUIT SHORT TO GROUND 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 Passenger Airbag.
Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See: A L L Diagnostic Trouble Codes ( DTC ) > Verification Tests > Restraint System Verification Test.
3. CHECK (R42, R44) PASSENGER SQUIB 1 CIRCUITS FOR A SHORT TO GROUND
imageOpen In New TabZoom/Print
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 (8443A) and Jumper from the Passenger Airbag Squib harness connectors.
2. Disconnect the ORC harness connectors.
NOTE: Check connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adapter (8443-57) to the ORC C1 harness connector.
4. Measure the resistance of the (R42) Passenger Squib 1 Line 2 circuit between the Passenger Airbag Squib 1 harness connector cavity 4 and ground.
5. Measure the resistance of the (R44) Passenger Squib 1 Line 1 circuit between and the Passenger Airbag Squib 1 harness connector cavity 3 and ground.
Is the resistance below 10K Ohms for either measurement?
Yes
Repair the (R42, R44) Passenger Squib 1 circuits for a short to ground.
Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See: A L L Diagnostic Trouble Codes ( DTC ) > Verification Tests > Restraint System Verification Test.
No
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. See: Air Bag Control Module > Removal and Replacement
Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See: A L L Diagnostic Trouble Codes ( DTC ) > Verification Tests > Restraint System Verification Test.
