Common Questions
What does C1412 mean and how does it affect my car?
C1412 signifies an issue with the ABS control module, which is vital for safe braking. If this module fails, your vehicle may not be able to prevent wheel lock-up during sudden stops, leading to potential accidents.
What are the most common causes of C1412 and how much does it cost to fix?
The primary cause is often a faulty ABS control module, which can cost between $800 and $1500 to replace. Other causes include wiring issues and software glitches, which can be less expensive to resolve.
Can I drive my car with C1412 or should I stop immediately?
It is not safe to drive with C1412 present, as the ABS system is disabled, potentially leading to loss of vehicle control during emergency braking. Immediate repairs are recommended.
How can I diagnose C1412 myself using GeekOBD APP?
Using the GeekOBD APP, connect to your vehicle's OBD2 port, retrieve the code C1412, and check any freeze frame data to understand the conditions under which the fault occurred.
What vehicles are most commonly affected by C1412?
C1412 is frequently reported in models such as the 2010-2015 Dodge Charger, 2011-2016 Jeep Grand Cherokee, and certain Chrysler 300 models. Always check for any recalls or Technical Service Bulletins (TSBs) related to the ABS system.
How can I prevent C1412 from happening again?
Regular maintenance, such as inspecting the ABS system during routine service, checking electrical connections, and ensuring that the brake fluid is at the proper level can help prevent future issues with C1412.
What is C1412?
The Diagnostic Trouble Code (DTC) C1412 indicates a malfunction within the Anti-lock Braking System (ABS) control module, particularly seen in various Dodge, Jeep, and Chrysler models. This code is triggered when the ABS control module detects a fault in its internal circuitry or communication issues with other vehicle control modules. The ABS system is crucial for maintaining vehicle stability and control during braking, especially in slippery conditions. When C1412 is present, it typically means that the ABS system is inoperative, which can lead to decreased braking performance and increased stopping distances. Drivers may experience symptoms such as the ABS warning light illuminating on the dashboard, and in some cases, the brake warning light may also activate. Ignoring this code can have serious safety implications, especially in adverse weather conditions, as the ABS helps prevent wheel lock-up during emergency braking. It is advisable for vehicle owners to address this issue promptly to ensure the safety and reliability of their vehicle's braking system.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1412 is present:
- The ABS warning light remains illuminated on the dashboard, indicating a problem with the ABS system.
- The brake pedal may feel different, such as being harder to press or having an unusual vibration during braking, which can be alarming for drivers.
- Drivers may experience decreased braking efficiency, particularly when driving on wet or slippery surfaces, leading to longer stopping distances.
- In some cases, the traction control light may also illuminate, signaling further issues within the vehicle's stability control systems.
- Unusual noises from the ABS pump when the vehicle is in motion can be an additional symptom, indicating potential component failure.
Possible Causes
Most common causes of C1412 (ordered by frequency):
- The most common cause of C1412 is a faulty ABS control module, which accounts for about 60% of cases. This can happen due to electrical issues, water intrusion, or internal component failure.
- Another possible cause is damaged wiring or connectors leading to the ABS module. Corrosion or frayed wires can disrupt communication and trigger the code.
- A third cause could be a malfunctioning wheel speed sensor, which provides crucial data to the ABS module for proper functioning. Regular inspections can prevent this issue.
- Less commonly, a software glitch in the ABS module may cause C1412, which can often be resolved by updating the vehicle's software.
- A rare cause could be a faulty brake pedal position sensor, which may affect the ABS operation and trigger the code, although this is not typically a primary concern.

Diagnostic Steps
Professional C1412 Diagnosis Process
Follow these systematic steps to accurately diagnose C1412. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Begin with an initial visual inspection to identify any obvious issues such as damaged wiring, loose connections, or signs of corrosion around the ABS control module (5-10 minutes)
Step 2: Use an OBD2 scanner, such as the GeekOBD APP, to retrieve all codes and freeze frame data, which can provide context for the fault (10-15 minutes)
Step 3: Conduct component testing using a multimeter or specialized diagnostic tools to evaluate the ABS control module and related sensors (20-30 minutes)
Step 4: Perform a system function test to ensure all components are working correctly post-repair, and clear any stored codes from the memory (10-15 minutes)
Step 5: Complete a road test under various conditions to verify the effectiveness of the repairs and ensure the ABS system is fully operational (15-20 minutes)
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
