B2001 Scion Code - Short To Ground In Seat Belt Motor Right Circuit
Quick Answer
The Seat Belt Control ECU receives information from the master cylinder solenoid (Skid Control ECU) via the Controlled Are Network (CAN) communication line and tightens the seat belt by operating the motor in the Front Seat Outer Belt Assembly Right (RH) or Left (LH). Common causes include Faulty Front Seat Outer Belt Assembly Right (RH), Front Seat Outer Belt Assembly Right (RH) harness is open or shorted, Front Seat Outer Belt Assembly Right (RH) circuit poor electrical connection. 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.

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.
Frequently Asked Questions about B2001 Scion Code
1. What are common symptoms of the OBDII code B2001 in a Scion related to a short to ground in the seat belt motor right circuit?
- Common symptoms include non-functional or erratic movement of the right seat belt motor, seat belt warning light illumination, and potential issues with the seat belt retracting properly.
2. What are possible causes of the B2001 code indicating a short to ground in the seat belt motor right circuit in a Scion?
- Potential causes include damaged wiring or connectors in the seat belt motor circuit, a faulty seat belt motor, or a short to ground within the circuit itself.
3. How can I diagnose the B2001 code related to a short to ground in the seat belt motor right circuit in my Scion?
- Diagnose the issue by inspecting the seat belt motor wiring for damage, checking the connectors for corrosion or loose connections, and using a multimeter to test for continuity and shorts in the circuit.
4. Can I repair the B2001 code myself if it indicates a short to ground in the seat belt motor right circuit of my Scion?
- If you are experienced with automotive electrical systems and have the necessary tools, you may be able to repair the issue yourself by identifying and fixing the short to ground, replacing damaged wiring or connectors, or replacing the faulty seat belt motor.
5. Is it safe to drive my Scion with the B2001 code triggered by a short to ground in the seat belt motor right circuit?
- It is not recommended to drive the vehicle with this issue unresolved, as it may compromise the effectiveness of the seat belt system and pose a safety risk in the event of a collision.
6. How much does it typically cost to repair the B2001 OBDII code related to a short to ground in the seat belt motor right circuit of a Scion?
- The cost of repair can vary depending on the extent of the damage and whether you choose to do the repair yourself or take it to a professional. Costs may include parts and labor.
7. Can the B2001 OBDII code be triggered intermittently due to a short to ground in the seat belt motor right circuit of a Scion?
- Yes, intermittent issues with the seat belt motor circuit can sometimes trigger the B2001 code, especially if there is a loose connection or a partial short to ground that occurs sporadically.
8. Will resetting the OBDII system clear the B2001 code associated with a short to ground in the seat belt motor right circuit of a Scion?
- Resetting the OBDII system may temporarily clear the code, but if the underlying issue causing the short to ground is not addressed, the code is likely to reappear after driving the vehicle.
9. Are there any safety implications if the B2001 code due to a short to ground in the seat belt motor right circuit is left unrepaired in a Scion?
- Leaving this issue unresolved can compromise the proper functioning of the seat belt system, potentially reducing its effectiveness in restraining occupants during a collision.
10. Can environmental factors like moisture or extreme temperatures contribute to the occurrence of the B2001 code indicating a short to ground in the seat belt motor right circuit of a Scion?
- Yes, environmental factors such as moisture or extreme temperatures can exacerbate electrical issues in the seat belt motor circuit, leading to shorts or other malfunctions that trigger the B2001 code.
