The B1359 code indicates a problem with the ignition switch circuit. It is triggered when the ignition switch signal does not meet the required specifications. This can be caused by a faulty ignition switch, a damaged or shorted ignition switch harness, or poor electrical connections.
Symptoms of this issue may include the illumination of the engine light.
To rectify the B1359 code, it is recommended to visually inspect the wiring harness and connectors for any damage and then carry out the necessary repairs.
The cost of diagnosing and fixing this code may vary depending on factors such as labor rates and the make and model of the vehicle.
What does it mean
The B1359 code indicates a problem with the Ignition Switch RUN/ACC circuit, causing the Ignition Switch signal to deviate from factory specifications. This can result in malfunctioning electrical systems.
Diagnosing the code requires a thorough inspection of components and connectors.
Prompt repairs are recommended to ensure safety and proper vehicle function.
what are the symptoms
The B1359 code often comes with the Engine Light or Service Engine Soon Warning Light turning on. Ignoring this code can harm the vehicle's performance and safety in the long run. Here are some signs that may indicate the presence of this code:
- Difficulty starting the engine
- Sometimes losing power or completely losing power to different electrical components
- Unable to turn off the ignition switch
- Accessories like the radio, power windows, or climate control not working
Even though there might not be a quick fix for the B1359 code, it's important to promptly address the issue to prevent further damage. Ignoring the code can lead to safety risks and more problems with the electrical system. It is recommended to have a qualified technician diagnose and repair the vehicle to ensure the ignition switch and related components work properly.
What are the causes
Possible causes of the B1359 code include:
- A faulty ignition switch
- Problems with the ignition switch wiring
- Poor electrical connections in the ignition switch circuit
- A faulty Smart Junction Box (SJB)
When diagnosing the B1359 code, it is important to avoid common mistakes that can lead to incorrect conclusions. These mistakes include:
- Not checking the wiring and connectors for damage
- Not inspecting connector pins for breakage, bending, or corrosion
- Not performing necessary repairs or replacements
It is crucial to visually inspect all components and connections to ensure they meet the required specifications. Failure to do so may result in misdiagnosis and unnecessary repairs.
What Tools are Needed to diagnose
To diagnose the B1359 code, technicians need specific diagnostic tools. Here are some important points to consider when discussing the tools needed for diagnosis:
- Importance of using a diagnostic scanner:
- A diagnostic scanner is crucial for accurate diagnosis. It helps retrieve and analyze trouble codes, enabling technicians to pinpoint the exact issue.
- The scanner provides real-time data from the vehicle's computer system. This data allows technicians to monitor various parameters and make informed decisions.
- Common tools used for diagnosing ignition switch-related issues:
- Technicians may use a multimeter to test voltage and continuity. This helps determine if the ignition switch is functioning properly.
- A wiring diagram is helpful for tracing the circuit and identifying any open or shorted wires.
- A scan tool that can access the Smart Junction Box (SJB) module is significant. It provides additional diagnostic information.
How to fix Step by Step
Step 1: Thoroughly inspect the vehicle's ignition switch and associated wiring harness. Look for any signs of damage such as broken, bent, or corroded connector pins.
Step 2: If any damaged components are found, repair or replace them as necessary.
Step 3: Test the Ignition Switch circuit using a multimeter to measure the voltage output. If the voltage does not meet factory specifications, consider replacing the ignition switch.
Step 4: Troubleshoot the Smart Junction Box (SJB) as it receives voltage from the Ignition Switch RUN/ACC circuit. Inspect the SJB for any signs of damage or corrosion.
Step 5: Perform any necessary repairs or replacements to the Smart Junction Box (SJB).
What are the Common Diagnosis Mistakes
One common mistake in diagnosing the B1359 code is not thoroughly checking the vehicle's ignition switch and wiring harness for damage. This can lead to missing the potential cause of the code and wasting time and effort.
To prevent this mistake, it is important to follow these troubleshooting steps:
- Conduct a visual inspection of the wiring harness and connectors to look for any damaged parts.
- Check for broken, bent, or corroded connector pins, as these can affect the ignition switch's functioning.
- Make any necessary repairs or replacements based on the inspection's findings.
What is the Repair Cost
The cost of repairing the B1359 code can range from $100 to $300. Factors such as location, vehicle make and model, engine type, and labor rates can affect the final cost.
Labor rates typically range from $75 to $150 per hour. For a more accurate estimate, consult a certified mechanic or contact local auto repair shops.
Can I drive safely with this code?
Driving safely with the B1359 code depends on the severity of symptoms. However, it is recommended to address the issue promptly if accompanied by an engine light or service engine soon warning light.
Ignoring the code may lead to further electrical malfunctions or power loss while driving, posing a safety risk.
Thorough inspection and repair of damaged parts are necessary.
Conclusion
In conclusion, the B1359 code indicates an issue with the ignition switch circuit. It is commonly caused by a faulty ignition switch, open or shorted wiring harness, or poor electrical connection. Symptoms may include the illumination of the engine light or service engine soon warning light.
It is important to visually inspect the wiring harness and connectors for any damage and perform necessary repairs. The cost to diagnose and fix the B1359 code may vary depending on various factors.
