Causes

Wiring chafed/damaged with insulation pierced and contacting chassis ground
Corroded, loose or contaminated connector at the right side impact sensor or at the SRS control module
Failed/right side airbag (side impact) sensor internal short
Aftermarket equipment or repair damage to harness routing (clips, rivets, body repairs)
Short in the connector or pin pushed into contact with ground
Faulty SRS control module or internal module connector fault

Symptoms

SRS / Airbag warning light ON
Possible disablement of right side airbag (side curtain/seat mounted) — airbags may not deploy in an impact
Diagnostic trouble codes stored (C2332 and possibly related SRS codes)
Vehicle may fail safety inspection or immobilizer interlocks in some markets

What to check

Retrieve all stored SRS codes and freeze-frame data with a capable scan tool; record related codes and timestamps
Visually inspect right side impact sensor, connector, and harness routing for damage, corrosion or body contact points
Inspect for recent body repair or aftermarket installations that may have disturbed the harness
With ignition off and battery disabled per manufacturer procedure, disconnect the right side impact sensor connector and inspect pins for corrosion, bent pins, or burnt insulation
Back-probe the sensor signal conductor and measure continuity to chassis ground and to the SRS module pin with key ON (or per manual)
Wiggle-test the harness and connectors while watching live data to see intermittent changes

Signal parameters

Circuit should NOT have continuity to chassis ground — normal: open/high resistance when sensor disconnected (refer to factory values)
When a short to ground is present the signal conductor will measure near 0 ohms to ground
Live-data or DTC status should show the right side sensor status as faulted when short present
Exact voltage/resistance specifications vary by model/year — consult Hyundai service manual and wiring diagram for pin-specific values

Diagnostic algorithm

Safety first: follow Hyundai procedure to disable SRS (disconnect negative battery terminal and wait the manufacturer-specified time) before touching connectors or sensors
Connect an OEM-capable scan tool and record all SRS-related codes and freeze-frame data. Note any communication or multiple-channel faults.
Visually inspect the right side impact sensor, its connector, and the harness path (under carpets, behind trim, inside seat/door) for damage, corrosion, pinching, or body contact.
With battery and SRS disabled, disconnect the right side sensor connector and inspect pins for corrosion or damage. Repair or replace connector as needed.
Re-enable power per safe procedure. Back-probe the sensor signal and measure continuity to chassis ground. A short will show low ohms (~0Ω). If short is present, trace harness along its length for chafing or grounding points.
If no short with connector disconnected, probe at the SRS control module connector to determine if the short is between module and harness or at the sensor end. Use wiring diagram to identify correct pin.
If harness and connectors check good, substitute a known-good sensor (if available) or bench-test the suspect sensor per factory procedure to confirm internal failure.
Repair wiring harness faults (splice/replace damaged section with proper crimps, heat shrink, loom) or replace the sensor. Replace SRS control module only after eliminating wiring/sensor faults and following immobilizer/airbag pairing procedures if required.
Clear codes, perform SRS system initialization per service instructions, and verify repair by cycling ignition and confirming no recurrence of C2332 and that SRS lamp extinguishes.
If intermittent or unresolved, consult Hyundai wiring diagrams and consider module-level diagnostics or dealer-level support.

Likely causes

Damaged harness between right side impact sensor and SRS control module (short to ground)
Contaminated/corroded connector at the sensor or module causing low-resistance path to ground
Failed side impact sensor showing internal short
Incorrectly routed or pinched wiring after collision repair

Fault status

⚠️ Status

SRS control module reports a short to ground on the right side airbag sensor circuit. DTC stored and SRS warning lamp illuminated; right side airbag circuit may be disabled until repaired.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1.0-3.0 hours
