* Low Brake Fluid: This is the simplest and cheapest thing to check first. Low brake fluid can trigger both warning lights. Top off the fluid reservoir (carefully, as brake fluid is corrosive) and see if the lights stay off. *However, if the fluid level is low, you have a leak somewhere in your brake system which needs immediate attention!*
* ABS Speed Sensor: These sensors are located on each wheel and measure wheel speed for the ABS system. A faulty sensor can send incorrect signals to the ABS module, triggering the warning lights. The delay before the lights go out might indicate a sensor that's intermittently failing.
* ABS Module: The ABS module is the "brain" of the system. An internal fault within the module can cause intermittent problems. This is a more expensive repair, potentially requiring replacement.
* Wiring Issues: Worn or damaged wiring related to the ABS system (especially near the wheels) can cause intermittent problems. Corrosion is common in older vehicles.
* Brake Switch: While less likely given the ABS light is also illuminated, a faulty brake switch could contribute. It's worth checking the switch's functionality and condition.
Troubleshooting Steps:
1. Check Brake Fluid Level: This is the absolute first step. A low level is a serious problem.
2. Have the System Scanned: Take your Durango to an auto parts store (like AutoZone or Advance Auto Parts) and have them scan the OBD-II system for trouble codes. The codes will give you a much better indication of the specific problem.
3. Inspect Wiring (if codes point towards wiring): Carefully examine the wiring harnesses leading to the ABS sensors and the ABS module for any signs of damage, corrosion, or loose connections.
4. Professional Diagnosis: If the self-checks and code reading don't pinpoint the problem, take your Durango to a qualified mechanic specializing in automotive electrical systems or brake systems. They have the tools and expertise to diagnose the issue properly.
Important Note: Driving with malfunctioning ABS can reduce your braking performance in emergency situations. While the lights turning off might seem to indicate a minor problem, it's best to address this promptly to ensure safe operation of your vehicle. Ignoring it could lead to a more serious and costly repair later.
