B2015 Scion Code - Open in Right Side Upper MOS
Quick Answer
The B2015 diagnostic trouble code (DTC) for Scion vehicles indicates an open circuit in the Right Side Upper MOS (Metal-Oxide-Semiconductor) module. Common causes include Corrosion: Exposure to moisture or contaminants can cause corrosion on the electrical connections, leading to an open circuit, Wiring Damage: Physical damage to the wiring harness, such as cuts, fraying, or breaks, can interrupt the flow of electricity, Loose Connections: Loose or improperly connected wires or terminals can result in an open circuit in the MOS module. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B2015 Scion Description
The B2015 diagnostic trouble code (DTC) for Scion vehicles indicates an open circuit in the Right Side Upper MOS (Metal-Oxide-Semiconductor) module. MOS modules are electronic components that control various functions within the vehicle, such as engine management, transmission control, and other critical systems. An open circuit in the Right Side Upper MOS can disrupt the communication and operation of these systems, leading to potential performance issues and safety concerns.
Common Causes of B2015 Scion
- Corrosion: Exposure to moisture or contaminants can cause corrosion on the electrical connections, leading to an open circuit.
- Wiring Damage: Physical damage to the wiring harness, such as cuts, fraying, or breaks, can interrupt the flow of electricity.
- Loose Connections: Loose or improperly connected wires or terminals can result in an open circuit in the MOS module.
- Component Failure: A malfunctioning MOS module or related component can also trigger this code, requiring replacement to resolve the issue.
Symptoms of B2015 Scion
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Engine Misfires: The vehicle may experience engine misfires or rough idling due to the disrupted communication between the engine management system and other components.
- Transmission Issues: Shifting problems, including harsh or delayed gear changes, can occur as a result of the open circuit in the MOS module.
- Electrical Malfunctions: Various electrical components, such as power windows, door locks, or lights, may not function properly due to the disrupted circuit.
How to Fix B2015 Scion
- Diagnostic Testing: Use a diagnostic scan tool to retrieve the specific DTC and pinpoint the location of the open circuit in the Right Side Upper MOS module.
- Visual Inspection: Inspect the wiring harness, connectors, and MOS module for any signs of damage, corrosion, or loose connections.
- Repair or Replace: Repair any damaged wiring or connectors, and replace the faulty MOS module if necessary to restore the circuit integrity.
- Clear DTC: After completing the repair, clear the DTC from the vehicle's memory using the diagnostic scan tool to reset the check engine light and verify the issue has been resolved.
- Functional Test: Perform a comprehensive test drive to ensure the affected systems are functioning properly and that the vehicle operates without any symptoms related to the open circuit in the Right Side Upper MOS module.
Cost to Fix B2015 Scion
The typical repair costs for addressing an open circuit in the Right Side Upper MOS module can range from $200 to $500, depending on the extent of the damage, the need for replacement parts, and the labor involved. This estimate includes the cost of diagnostic testing, repair materials, replacement components, and labor charges. It's important to note that the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Auto repair shops commonly charge between $80 and $150 per hour for labor, with rates potentially higher in metropolitan areas or at dealerships, and lower at independent shops. For a more precise estimate, it's recommended to inquire with local auto repair facilities.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
