What does it mean when the p light keeps flashing?

[LeHarley]

The p light in a car is the brake system warning light, also known as the parking brake warning light. When the p light comes on, it indicates that there is a fault in the car's braking system. In such cases, the car should be pulled over immediately for inspection to avoid potential safety hazards. Below is an analysis of situations when the p light comes on: 1. Computer issue: When the car is initially powered on, the onboard computer performs a self-diagnosis check. During this time, all warning lights on the dashboard will illuminate. Once the check is complete, the warning lights will turn off. This is a normal phenomenon and does not require attention. However, if the warning lights remain on after the computer completes its self-diagnosis, it indicates a fault, and the car should be inspected and repaired as soon as possible. 2. Fault occurrence: If the brake system warning light comes on while driving, it means there is a fault in the car's braking system. This could be due to damaged brakes or the parking brake not being fully released. In such situations, the car should be pulled over for inspection to prevent any safety risks.
