What it means
The restraint module monitors the secondary restraint-system malfunction indicator. It sets this code when the indicator’s circuit or response does not meet the module’s expected criteria.
At a glance
- Usually lights the airbag (SRS) or body-system warning light
How it works
The restraint control module checks the circuit or feedback for the secondary restraint-system malfunction indicator, which may be a separate lamp or display symbol. This code sets when that indicator’s electrical response does not match what the module expects, so the warning may not appear when needed.
Common causes
Most likely first.
- Failed warning lamp or display
- Open or short in indicator wiring
- Loose or corroded connector
- Fault in the restraint control module
Symptoms
- Warning light or symbol related to the affected system
- Comfort or safety function impaired
How to diagnose it
- Scan the restraint module for related codes and freeze-frame or event data to see whether the fault is logged as an indicator circuit or response problem.
- With the ignition on, check whether the secondary restraint warning lamp or display symbol illuminates during its normal self-check.
- Inspect the indicator and its visible wiring or connectors for damage, looseness, corrosion, or signs of a failed lamp or display.
- Use the vehicle wiring information to test the indicator circuit for an open or short and compare results with the manufacturer’s specification.
- If the indicator and wiring pass, check the restraint module’s output and feedback using the manufacturer’s diagnostic procedure.
Common fixes
- Repair a loose or corroded indicator connector.
- Repair damaged wiring or an open or short in the indicator circuit.
- Replace the failed warning lamp or repair the display, as applicable.
- Repair or replace the restraint control module if its indicator output is confirmed faulty.
Can I keep driving?
The restraint system may not clearly warn you of a fault, and a related safety function could be impaired. Arrange diagnosis promptly and treat any restraint warning as active.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
