B1B06 Jeep driver airbag squib 2 circuit open

B1B06 driver airbag squib 2 circuit open (Jeep)

B1B06 in short

On Jeep, B1B06 means the airbag controller sees an open circuit on the second driver airbag igniter (squib 2). On Wrangler complaints the clockspring behind the steering wheel was the faulty part. The car usually drives, but the driver airbag may not fire, so get it checked soon.

The driver airbag has more than one igniter. The airbag controller tests each one, and B1B06 is the readout for an open circuit on the second one.

The two Wrangler complaints we read tie B1B06 to the clockspring, the rotating connector in the steering column. One shows an internal short found in the clockspring and the part replaced. It often appears with B1B02, the same fault on squib 1.

Airbag circuits can fire if handled wrongly, so testing is for a technician.

Pick your make

B1B06 is a manufacturer-specific code: its meaning depends on who built the car.

Other makes: meaning not verified. Check with a scan tool that reads manufacturer definitions.

Most likely causes

  1. Clockspring (rotating connector) in the steering column

    Supported by vehicle data
    Why it ranks here
    A dealer found an internal fault in the clockspring on a B1B06 Wrangler and replaced it, and another owner says the code points to the clockspring. Jeep bulletins for the Wrangler also call for clockspring replacement for these airbag codes.
    What would change this
    Rises if the light flickers as the wheel turns or B1B02 is stored too. Falls if the code stays after the clockspring is replaced.

  2. Driver airbag module or its connector

    Possible — needs testing
    Why it ranks here
    It is the other part on the squib circuit; this is a weaker candidate than the clockspring on the cases we read.
    What would change this
    Rises if the clockspring tests good.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Have a shop with an SRS-capable scan tool read the airbag module and note every stored code, current or history, and whether the fault is current.

    Warning:Airbag and seat belt pretensioner circuits can deploy if probed or disconnected incorrectly. Only a trained technician following the service manual should test them.

      It meansThe shop checks the clockspring and the squib circuit wiring.

      Points to: Clockspring (rotating connector) in the steering column

    • IfThe fault does not return after the shop clears it and checks the connectors

      It meansThe fault may have been intermittent. Do not assume it is gone; the airbag light should stay off through several drives.

Symptoms

  • Airbag light flashing or on at random times while driving

How to fix

This is a safety-critical system, so we explain the code but don't give repair steps. Have it inspected by a qualified technician.

B1B06 questions

Is it safe to drive with B1B06 and the airbag light on?

The car usually still drives normally, but manufacturers say the airbags may not work as designed while the light is on. Get it checked soon and do not rely on the airbags until it is.
