What it means
This code identifies a fault associated with the second row left frontal stage 2 deployment control. The restraint control module sets it when it detects a problem in that deployment control; the exact fault is specified by accompanying subfault information.
How it works
The restraint control module monitors stage 2 of the second-row left frontal airbag deployment circuit. B0032 indicates a fault in this stage's electrical path; the accompanying subfault information helps distinguish an open, short, or out-of-range circuit.
Common causes
Most likely first.
- Second row airbag wiring or connector fault
- Open or shorted deployment circuit
- Faulty airbag module
- Restraint control module fault
Symptoms
- Airbag warning light on
- Second row left frontal airbag stage may be unavailable in a crash
How to diagnose it
- Read the SRS subfault and event data to confirm the fault is on stage 2 of the second-row left frontal airbag.
- Inspect the rear-left seatback airbag area and harness for damage, pinching, prior seat or upholstery work, and loose connections.
- Disable the SRS using the vehicle procedure before inspecting accessible connectors; do not measure directly across an inflator.
- Test the stage 2 circuit with the manufacturer's approved SRS equipment for the specific open, short, or resistance condition reported.
- If wiring and connectors pass, use the specified procedure to assess the airbag module and restraint control module, then rescan after repair.
Common fixes
- Secure a loose stage 2 connection or repair damaged seatback wiring using the approved SRS repair procedure.
- Repair a confirmed open or short in the second-row left stage 2 deployment circuit.
- Replace the airbag module if its stage 2 circuit fails the manufacturer's specified test.
- Replace or program the restraint control module only after the stage 2 circuit and airbag module pass their checks.
Can I keep driving?
Stage 2 of the second-row left frontal airbag may not deploy as intended, so rear-passenger crash protection can be reduced. Have the SRS system checked promptly and avoid disturbing the seatback airbag wiring.
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.
