Common Questions
What does C0608 mean and how does it affect my car?
DTC C0608 indicates a malfunction in the Brake Control Module, which is critical for ensuring that your vehicle's ABS and braking system function correctly. If this module isn't operating properly, it can lead to serious braking issues, including longer stopping distances and reduced vehicle control, which can be dangerous.
What are the most common causes of C0608 and how much does it cost to fix?
Common causes include a faulty brake control module, damaged wiring, or software issues. Repair costs for replacing the BCM typically range from $300 to $800, depending on the vehicle make and model and whether any additional repairs are needed.
Can I drive my car with C0608 or should I stop immediately?
It is not advisable to drive your vehicle with C0608 present. The malfunctioning brake control module can severely affect braking performance, which poses a safety risk. It's best to address this issue before driving further.
How can I diagnose C0608 myself using GeekOBD APP?
Using the GeekOBD APP, you can perform a full OBD2 scan to check for DTCs, including C0608. The app will provide freeze frame data, which helps in understanding the conditions under which the code was triggered, and allows for clearing the code after repairs.
What vehicles are most commonly affected by C0608?
This code is frequently encountered in vehicles such as the 2013-2018 Dodge Ram and Jeep Grand Cherokee. These models have known issues with their Brake Control Modules, and it's advisable to check for any recalls or technical service bulletins (TSBs) related to braking systems.
How can I prevent C0608 from happening again?
To prevent C0608 from recurring, ensure regular maintenance checks on your braking system, keep wiring and connectors clean and free of corrosion, and stay updated on software updates from your vehicle manufacturer.
What is C0608?
DTC C0608 refers to a malfunction within the Brake Control Module (BCM). This code typically indicates that the BCM is not communicating properly with other modules in the vehicle, which can lead to a range of issues. When the BCM fails, it may cause the anti-lock braking system (ABS) to malfunction, potentially compromising vehicle safety. Drivers may notice symptoms such as the ABS warning light illuminating on the dashboard, erratic brake response, or a complete loss of ABS functionality. In severe cases, the vehicle could experience increased stopping distances, which can be dangerous. This DTC is particularly common in vehicles like the 2013-2018 Dodge Ram and Jeep Grand Cherokee, where the brake system is integral to overall vehicle performance. Addressing C0608 promptly is crucial as it not only affects braking efficiency but can also lead to complications in other systems reliant on the BCM’s correct operation. If you notice any symptoms associated with this code, it’s essential to seek a professional diagnosis and repair, as ignoring the issue could lead to costly repairs down the road or even a safety hazard while driving.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0608 is present:
- The ABS warning light stays illuminated on the dashboard, indicating a potential brake system issue.
- Drivers may experience a noticeable decrease in braking efficiency, especially during sudden stops.
- Erratic brake response, where the brakes may feel spongy or unresponsive at times, can be a significant concern.
- Increase in stopping distance, which can be measured through real-world driving experiences.
- Unusual noises from the brake system, such as grinding or squeaking, can accompany this code.
Possible Causes
Most common causes of C0608 (ordered by frequency):
- The most common cause is a faulty brake control module, with a likelihood of approximately 60%. This can occur due to electrical issues or internal component failure.
- Another potential cause is damaged wiring or connectors related to the BCM, which can disrupt communication. This issue may occur due to corrosion or wear over time.
- Software glitches can also lead to code C0608. Regularly updating the vehicle’s software can help prevent this issue.
- Less common but serious causes include water intrusion into the BCM, which can cause significant damage and require complete module replacement.
- A rare but possible cause is battery voltage issues; if the vehicle’s battery is weak or failing, it can impact the operation of the BCM.
