Modern Toyota vehicles use an Electronically Controlled Brake (ECB) system governed by a Skid Control ECU (brake actuator assembly). This computer continuously monitors the electrical state of the ABS pump motor.
A: Yes, Toyota confirms the system may store DTC C052F14 due to a drop in battery voltage. In this case, driving the vehicle over 9 mph for about half a second can clear it. However, repeated occurrences after this procedure point to a faulty battery, alternator, or other permanent issue.
Modern Toyota vehicles rely on an Electronically Controlled Brake (ECB) system, where an electronic skid control computer (brake actuator assembly) manages hydraulic brake pressure. i--- Toyota C052f14
: Check the high-amp fuse (typically around 40 amp) dedicated to the ABS pump motor operation.
If the actuator is faulty, it must be replaced. After installation, a technician must perform an acceleration sensor zero point calibration to ensure the system recognizes the new part correctly. Warranty Note In this case, driving the vehicle over 9
Measure the resistance between the ABS chassis ground wire and the negative terminal of the battery. High resistance here signals a corroded ground connection that needs to be sanded and re-bolted. 4. Perform an Active Bi-Directional Scanner Test
This code indicates that the vehicle's computer has detected a short to ground or an open circuit : Check the high-amp fuse (typically around 40
A drop in battery voltage can trigger this code. Ensure the battery is fully charged and healthy before replacing parts.
Once repairs are complete:
The primary ABS light, Brake System warning light, and stability control indicators will illuminate.
