Causes

Damaged or disconnected curtain airbag connector or wiring (open, short to ground, short to battery)
Corroded or pushed-out connector in headliner, A-pillar or door area
Faulty curtain airbag module (squib)
Faulty Restraints Control Module (RCM) or airbag diagnostic unit
Poor battery voltage or intermittent power/ground to SRS module
CAN/data-bus communication fault between airbag module and RCM

Symptoms

SRS/airbag warning light illuminated on instrument panel
Associated SRS fault(s) stored in diagnostic memory
Possible deactivation of curtain airbag deployment function
Vehicle may show multiple related restraint system codes
No other drivability symptoms in many cases

What to check

Read and record all SRS codes and freeze-frame data with a capable diagnostic tool
Verify battery voltage is within specification (stable ~12.6 V) and battery terminals are clean/tight
Perform visual inspection of curtain airbag wiring, connectors in headliner, A-pillar and door areas
Check for signs of water ingress, corrosion, aftermarket modifications or previous body repairs
Confirm RCM and airbag module connectors are fully seated and locked
Check for lost or abnormal CAN bus messages between RCM and restraint components

Signal parameters

SRS module status flags/diagnostic trouble code detail (via OEM diagnostic tool)
Curtain airbag squib circuit resistance (compare to spec in service manual)
Presence and frequency of CAN messages for restraint system and curtain module
Supply voltage to airbag module (key on and cranking) and ground integrity
Continuity and short-to-ground/short-to-battery checks on airbag harness circuits

Diagnostic algorithm

Connect a capable OEM or equivalent SRS diagnostic tool. Record all stored codes, freeze frame and module status.
Verify battery state-of-charge and charging system; ensure stable supply during testing.
Inspect harness, connectors and routing for the curtain airbag (headliner / A-pillar / roof rail). Repair any damaged insulation or corroded terminals.
With battery disconnected per manufacturer procedures, measure squib circuit resistance and continuity to the RCM; compare to factory values. Do NOT attempt to fire/activate airbags.
Check for intermittent faults: perform wiggle tests on wiring/connectors while monitoring live data/logs for changes.
Verify integrity of chassis grounds and power feeds to the RCM and curtain module.
Use the diagnostic tool to check for CAN/data-bus faults and module communication errors; address bus issues if present.
If wiring and connectors are good but fault persists, consider module-level faults: reflash or replace the curtain airbag module or RCM per OEM procedures. Follow all SRS safety precautions when handling or replacing modules.
After repair, clear codes, perform SRS self-tests and confirm the code does not return. If available, perform a full system test and road test per manufacturer recommendations.
If crash data / deployment flags are present, follow OEM process for module replacement and system reset; do not attempt repairs that conflict with post-deployment requirements.

Likely causes

Wiring/connectors to curtain airbag (most common)
Curtain airbag squib/module fault
RCM or control module communication failure
Intermittent battery/power or ground issue
