Your truck’s normal brakes will operate as usual, but without the ABS. The RAM 2500 / 3500 ABS warning light (anti-lock braking system) remaining on means there’s a problem detected. An indication that it’s a brake booster fault is that the ABS pump will run when applying the brake and you’ll feel a pulsation through the brake pedal. If the parking brake is off and the brake fluid is at the correct level, it may indicate a problem with the brake hydraulic system or a problem with the brake booster has been detected by the Anti-Lock Brake System (ABS) / Electronic Stability Control (ESC) system. If the brake fluid is low and requires frequent topping up, it usually indicates a leak in the dual brake system. The RAM 2500 / 3500 brake warning light comes on due to either the parking brake being applied or if the parking brake is off and the brake warning light remains lit, then the brake fluid level is low or that there is a problem with the Anti-Lock Brake System reservoir.

The usual reason why the airbag light stays on is due to crash sensors, the seat belt buckle not securely clipping int place or sometimes the cables / connection to the seat belt pretensioner under the front seats has become dislodged. The light remains illuminated along with an audible alert if a fault has been detected with the airbag. The RAM 2500 / 3500 airbag warning light stays illuminated for between 4 to 8 seconds as a bulb check when the ignition is switched to on. Dashboard display design and warning light location will vary depending on your version model and year of manufacture. This includes some modern systems that older versions of the RAM truck may not have.
