Table of contents
B1B01 MITSUBISHI Possible Causes
- Faulty Driver Airbag Squib 1
- Driver Airbag Squib 1 harness is open or shorted
- Driver Airbag Squib 1 circuit poor electrical connection
- Faulty Driver Airbag
- Faulty Steering Comun Control Module (Clockspring)
- Faulty Occupant Restraint Controller (ORC)
How do I fix code B1B01 MITSUBISHI?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the B1B01 MITSUBISHI code
The cost of diagnosing the B1B01 MITSUBISHI code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
This Diagnostic Trouble Code (DTC) sets when the ORC detects a short to ground on the driver airbag squib circuit for more than 2.5 seconds. This DTC transitions from active to stored when the ORC sees a recovery from a short to ground for greater than 2.5 seconds.
Possible Symptoms
- Air Bag Warning Light ON
B1B01 MITSUBISHI Description
When powered, the Occupant Restraint Controller (ORC) sends a test current to the squibs to verify the integrity of the squib and wiring. These circuits are maintained in a “floating” configuration at the module (connected to neither power nor ground) as protection against inadvertent deployment. The use of the SRS Load Tool Adaptor provides a test point as well as a method for opening the shorting bar connections within the harness connector. The Clockspring is part of the Steering Column Control Module (SCCM). The SCCM includes the steering column shroud, the Steering Angle Sensor (SAS), the Clockspring, the Multi-function Switch, a Steering Column Power Tilt and Telescope Switch (if equipped), and a trim cover. The SCCM is replaced as an entire assembly. The ORC Module sends out a 40 mA diagnostic current on each squib voltage supply circuit at power up, and every 500 ms thereafter while the ignition is on.
