The cost to diagnose the B1B04 MITSUBISHI code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
This Diagnostic Trouble Codes (DTC) sets when the ORC detects a short to ground on the 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 condition for greater than 2.5 seconds.
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 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.
