This code means that the car's computer is having trouble talking to the brakes' computer. It's like when your phone can't connect to the internet.
The P1773 code indicates a communication issue between the vehicle's main computer and the ABS control module over the Controller Area Network (CAN) bus.
The ABS control module is responsible for managing the anti-lock braking system, which prevents the wheels from locking up during braking. The CAN bus is a communication system that allows different parts of the car to talk to each other. A timeout error suggests that the main computer is not receiving a response from the ABS module within the expected time frame.

This code has been more prevalent in vehicles with complex electronic systems, particularly those from the early 2000s.
Moderate – While the car can still be driven, ABS functionality is compromised, which can affect safety.
Driving with a malfunctioning ABS system can be dangerous, especially in wet or icy conditions.
• Vehicle stationary
• Ignition on, engine off
The ABS control module is typically located near the brake master cylinder or within the engine bay.
Q: Can I drive with the P1773 code?
A: While you can drive, it's not recommended as your ABS may not function properly, affecting braking performance.
Q: How do I reset the ABS light?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
