When a brake system error occurs, do the following:
-OBD-II scanner error codes (if available),
Check the brake fluid level in the bachka as well as its condition. If there are signs of foam, the fluid needs to be replaced.
-View the transaction and check the status of the ABS sensors.
-Measure the voltage of the battery.
-Check the tire pressure. Sometimes, at different tyre pressures, the ABS electronics determine the difference in wheel adhesion to the surface and issues an error.
