The B1317 code refers to a high battery voltage in either the Four-Wheel Antilock Brake (4WABS) Control Module or the Generic Electronic Module (GEM). This code indicates an issue with the vehicle's charging and electrical system.
Symptoms of the B1317 code may include a check engine light or a battery warning light appearing on the dashboard. Other symptoms may include erratic electrical behavior, such as flickering lights or unresponsive power windows.
The causes of the B1317 code can vary, but common culprits include a defective battery, a faulty alternator, or poor electrical connections. It is important to address this code promptly to avoid further damage to the vehicle's electrical components.
To fix the B1317 code, start by checking the battery's voltage and condition. If the battery is defective, it should be replaced. Next, inspect the alternator for any faults or malfunctions. If necessary, have the alternator repaired or replaced. Additionally, ensure that all electrical connections are clean and secure.
If the issue persists after these steps, it is recommended to consult a professional mechanic or technician for further diagnosis and repair. They will have the necessary tools and expertise to accurately identify and resolve the B1317 code.
What does it mean
The B1317 code indicates a high battery voltage issue in the vehicle's electrical system. It can be caused by various factors such as a defective battery, loose alternator drive belt, faulty alternator, or poor electrical connections.
It is important to visually inspect the wiring harness and connectors for any damage and check for broken or corroded pins.
what are the symptoms
The symptoms of the B1317 code include the Engine Light or Service Engine Soon Warning Light turning on. This indicates a problem with the vehicle's electrical system, specifically a high battery voltage issue.
Here are some steps you can take to troubleshoot the B1317 code:
- Check the battery: Start by inspecting the battery for any defects or signs of damage. A faulty battery can cause high voltage problems in the electrical system.
- Inspect the alternator drive belt: Make sure the alternator drive belt is properly tightened and not missing. A loose or missing belt can result in irregular charging and high voltage issues.
- Test the alternator: Use a multimeter to check the output voltage of the alternator. If the alternator is faulty, it may not regulate the voltage correctly, leading to a high battery voltage problem.
- Inspect the electrical connections: visually examine the alternator harness for any signs of open circuits or shorts. Also, check for any poor electrical connections and corroded connector pins.
Whate are the causes
There are several possible reasons for the B1317 code, including:
- Faulty battery: A defective battery can cause high battery voltage, which triggers the B1317 code.
- Loose or missing alternator drive belt: If the belt that drives the alternator is loose or missing, it can affect the charging system and result in high battery voltage.
- Malfunctioning alternator: A faulty alternator can overcharge the battery, leading to high battery voltage.
- Open or shorted alternator harness: An open or shorted wiring harness in the alternator circuit can disrupt the flow of electricity and cause high battery voltage.
High battery voltage can have various effects on vehicle performance, such as:
- Overcharging the battery, which can damage it and reduce its lifespan.
- Disrupting the electrical system, affecting different components and functions.
- Creating a potential risk of electrical fires or other safety hazards.
It is crucial to address the root causes of high battery voltage to prevent further damage to the vehicle and ensure optimal performance.
What Tools are Needed to diagnose
In order to diagnose the B1317 code and identify the reasons behind high battery voltage, professional automotive technicians require a specific set of tools. Here are the tools needed to diagnose a B1317 code:
- Diagnostic scanner: A diagnostic scanner is necessary to read and retrieve the trouble codes stored in the vehicle's onboard computer system. It allows technicians to access the B1317 code and other related codes for further analysis.
- Multimeter: A multimeter is used to measure voltage, resistance, and continuity in the electrical circuits. It helps technicians check the battery voltage, alternator output, and the integrity of the wiring and connectors.
- Wiring diagram: A wiring diagram provides a visual representation of the electrical circuits in the vehicle. It helps technicians locate the specific components and connectors related to the B1317 code.
- Insulation piercing probe: An insulation piercing probe is used to access the electrical wires without damaging the insulation. It allows technicians to test the voltage and continuity of the wires while the system is operating.
Common mistakes in diagnosing a B1317 code include overlooking loose or corroded connections, failing to conduct a thorough visual inspection of the wiring and connectors, and not following the diagnostic procedure specified by the vehicle manufacturer.
How to fix Step by Step
Step 1: Begin by using the necessary tools and equipment for the diagnostic procedure of the B1317 code.
Step 2: Avoid assuming that the issue is solely related to the battery or alternator. Thoroughly inspect the wiring harness and connectors for any damage or corrosion.
Step 3: Check for any broken, bent, pushed out, or corroded connector pins as they can contribute to the B1317 code.
Step 4: Perform regular maintenance of the charging system and electrical system in the vehicle to prevent the B1317 code from occurring in the future.
Step 5: Check the battery, alternator drive belt, and connections for any signs of wear or damage during the regular maintenance.
Step 6: Promptly address any issues found during the maintenance to minimize the likelihood of the B1317 code reoccurring.
What are the Common Diagnosis Mistakes
Common Diagnosis Mistakes:
One common mistake when diagnosing the B1317 code is not thoroughly checking the wiring and connectors for damage or corrosion. This oversight can contribute to the problem.
To avoid complications and ensure an accurate diagnosis, it is important to follow these guidelines:
- Visual inspection: Carefully examine the wiring and connectors for any signs of damage, such as fraying, cracks, or loose connections. It's also important to check for any greenish or white residue, which could indicate corrosion.
- Electrical continuity test: Use a multimeter to check the continuity of the wiring. This will help identify any open or short circuits that may be causing the B1317 code.
- Check for loose or bent pins: Inspect the connector pins for any signs of being pushed out of place, bent, or corroded. These issues can disrupt the electrical connection and trigger the B1317 code.
- Importance of regular maintenance: Regularly maintaining and inspecting the vehicle's electrical system can help prevent issues like the B1317 code. Keeping the wiring and connectors clean and in good condition can go a long way in avoiding potential complications.
What is the Repair Cost
The repair cost for the B1317 code can vary due to factors like location, vehicle make and model, and engine type. It can be generated from different modules, such as the 4WABS Control Module or GEM.
Common mistakes include overlooking battery, alternator, or wiring issues.
Labor rates range from $75 to $150 per hour.
Can I drive safely with this code?
Driving safely with the B1317 code is not recommended. It indicates high battery voltage and can lead to further damage to the vehicle's electrical components.
It is crucial to address the issue promptly to prevent safety hazards or power loss. Consult a professional mechanic to diagnose and repair the problem for safe operation.
