The B1207 code indicates a potential issue with the Passenger Air Bag circuit in the vehicle’s Air Bag Control Unit. This code is triggered when there is an overcurrent detected by the Occupant Restraint Controller, indicating a possible short circuit in the Passenger Air Bag Indicator.

One noticeable symptom of this code is the illumination of the Air Bag Warning Light. Possible causes of the B1207 code include a faulty Passenger Air Bag Indicator Lamp or a faulty Occupant Restraint Controller.

To fix this issue, it is recommended to inspect and replace any faulty components mentioned above.

B1207 Code Meaning, Causes, Symptoms, & How to Fix

Meaning

The B1207 code indicates a problem with the Passenger Air Bag Indicator circuit. This code is triggered when the Occupant Restraint Controller (ORC) detects an overcurrent on the circuit.

One common symptom is an illuminated air bag warning light on the dashboard. Regularly inspect and repair any damaged wiring or connectors associated with the indicator lamp to prevent the code.

Take precautions when servicing SRS air bags and seat belt pre-tensioners to avoid accidental deployment and injury.

Symptoms

The B1207 code may cause the air bag warning light on the dashboard to turn on. To avoid this code, it is important to regularly maintain the airbag system.

This involves checking for any damage to the wiring and connectors, inspecting for broken or corroded pins, and fixing or replacing any faulty parts.

Regular maintenance is essential to ensure the airbag system works properly and is reliable. By keeping the system in good condition, the chances of experiencing issues and error codes like B1207 are minimized.

It is recommended to follow the manufacturer’s maintenance schedule and guidelines to maintain the airbag system in optimal condition.

Causes

The B1207 code can be triggered by a faulty Passenger Air Bag Indicator Lamp or a short circuit in the Passenger Air Bag Indicator circuit. Here are some possible causes and steps to troubleshoot the B1207 code:

Faulty Passenger Air Bag Indicator Lamp: A broken or malfunctioning indicator lamp can cause the B1207 code. Check the lamp for any signs of damage or malfunction.

Open or shorted wiring harness for the Passenger Air Bag Indicator Lamp: Inspect the wiring harness connected to the indicator lamp for any open or short circuits. Repair or replace any damaged wiring.
Poor electrical connection in the Passenger Air Bag Indicator Lamp circuit: Make sure there are no loose or corroded connections in the circuit. Clean or tighten any connections as needed.
Faulty Occupant Restraint Controller (ORC): The ORC might be responsible for the B1207 code. Test the ORC and replace it if necessary.

Other potential causes not mentioned: There could be other factors that contribute to the B1207 code. Conduct a thorough inspection and diagnostic procedure to identify any additional causes.

Tools Needed to diagnose

To diagnose the B1207 code, you will need specific tools for the job. Here are some ideas for the tools required:

Diagnostic scan tool: You will need a good quality scan tool to retrieve the B1207 code and other relevant trouble codes. This tool allows communication with the vehicle’s onboard computer system.

Multimeter: A multimeter will come in handy for testing the electrical circuits associated with the Passenger Air Bag Indicator. It helps identify any issues like open circuits, shorts, or poor electrical connections.
Wiring diagram: It is essential to have a wiring diagram specific to the vehicle model. This diagram helps in understanding the circuitry and finding the components involved in the B1207 code.
Airbag system service manual: Referring to the manufacturer’s service manual for the particular vehicle is crucial. This manual provides accurate diagnosis and repair procedures for the airbag system.

Safety equipment: Since you will be working with the Supplemental Restraint System (SRS), it is vital to use safety equipment like gloves and safety glasses. These protect you from accidental airbag deployment.

Having these tools and taking necessary safety precautions will enable you to diagnose the B1207 code effectively.

How to fix Step by Step

Step 1: Consult the service manual for your specific vehicle model to access the instructions for fixing the B1207 code.

Step 2: Gather the necessary diagnostic tools and safety equipment before starting the repair process.

Step 3: Begin by visually inspecting the wiring harness and connectors related to the B1207 code.

Step 4: Check for any signs of damage, such as broken, bent, pushed out, or corroded connector pins.

Step 5: Repair or replace any faulty parts that are identified during the inspection.

Step 6: Be cautious not to probe the electrical connectors on air bags, side air curtain modules, or seat belts to avoid accidents.

Step 7: Avoid disassembling or tampering with safety belt buckle/retractor pretensioners.

Step 8: Follow the precautions outlined in the service manual and ensure that both battery cables are safely disconnected before servicing the SRS.

Step 9: Failure to follow these instructions may result in accidental deployment of the air bag and seat belt pre-tensioner, leading to serious personal injury or death.

Common Diagnosis Mistakes

One common mistake in diagnosing the B1207 code is not following the proper precautions listed in the service manual. This can result in using incorrect troubleshooting methods and overlooking common wiring problems.

To prevent these errors, technicians should:

Always consult the service manual for specific instructions and precautions.
Use the recommended diagnostic tools and equipment.

Inspect the wiring harness and connectors for any signs of damage or loose connections.
Check for any broken, bent, pushed out, or corroded connector pins.
Conduct a thorough visual inspection of all related components.

Repair Cost

The cost of repairing the B1207 code can vary depending on factors such as location, make and model of the vehicle, and engine type. On average, the diagnosis process can take around 1.0 hour of labor.

The repair cost itself will depend on whether any parts need to be replaced, such as the Passenger Air Bag Indicator Lamp or the Occupant Restraint Controller (ORC).

Can I drive safely with this code?

It is not safe to drive with the B1207 code. This code indicates a fault in the Passenger Air Bag Indicator circuit, which can lead to the airbag warning light being illuminated. Driving with a faulty airbag system poses a risk as the airbags may not deploy properly in a collision, increasing the chance of serious injury or death.

Promptly address the B1207 code for vehicle safety. Repair costs vary based on factors like location, make, and model of the vehicle, as well as required parts and labor rates.

Wrapping Up

The B1207 code indicates a potential issue with the Passenger Air Bag circuit in the vehicle’s Air Bag Control Unit. This code is triggered when the Occupant Restraint Controller detects an over current, suggesting a shorted circuit in the Passenger Air Bag Indicator.

The main symptom is the Air Bag Warning Light being illuminated. Possible causes include a faulty Passenger Air Bag Indicator Lamp, open or shorted harness, poor electrical connection, or a faulty Occupant Restraint Controller.

Proper caution must be exercised when servicing SRS components to avoid accidental deployment and injury.
