Changes to vehicles have forced manufacturers to introduce low-viscosity formulations for DOT 4 and DOT 5.1 brake fluids.

A great piece of advice is not to erase codes to see if they come back.
These types of bearings are used by Toyota, VW and many other import nameplates.
When debris gets trapped inside the ABS module, it can prevent the solenoids from fully closing after opening.

Some 2012-’13 model year Camry vehicles may exhibit a condition where ABS brake actuator pump motor noise is heard from the engine compartment with Brake ABS and/or TRAC warning lamp(s) illuminated and DTC C1431 stored.
Firing the “parts cannon” at an active ABS wheel speed sensor code often results in a misdiagnosis and an unhappy customer. It may start with the wheel bearing hub unit or wheel speed sensor. If those parts do not resolve the problem, the technician may fire the parts cannon at the ABS hydraulic control module. Typically, the customer’s patience and wallet runs out before the car is fixed.
Electronic stability control (ESC) became a mandated safety feature for the 2012 model year. Along with all of these advancements, false activation complaints have surfaced. Solving them has been a diagnostic conundrum through the years. False activation incidents involve the ABS modulator taking over braking or intervening to restore vehicle stability. The customer may feel feedback in the brake pedal like a pulsation or sudden drop. Some may also experience a drop in power or the vehicle may suddenly pull in one direction.
On early models, wheel speed sensors send an AC voltage signal to the ABS control module. On later models, active wheel speed sensors change the voltage signal produced by the ABS control module. Active wheel speed sensors are more accurate and work at lower speeds. This is why they are found on most Nissan/Infiniti models after 2012.
