It must read matching battery voltage (roughly ). If no power is present, a broken wire exists between the fuse block and the connector plug. 3. Run a Bi-Directional Diagnostic Output Test

If the light persists, use an OBD2 scanner with ABS capabilities to clear the code and confirm the fault is resolved. Safety & Maintenance

: Check the high-amp fuse (typically around 40 amp) dedicated to the ABS pump motor operation. i--- Toyota C052f14

If power and ground are verified at the module, the internal ABS motor relay or the module itself may be faulty. Recommended Steps ABS Pump Failure Symptoms – How To Test And Fix!

The Skid Control ECU continuously monitors voltage levels at the (the dedicated power feed for the pump motor) and the +BS terminal (system battery voltage supply). It must read matching battery voltage (roughly )

Diagnosing the root cause requires a systematic approach. The issue is almost always electrical, residing within the circuit itself or in related components. Based on Toyota technical information, here are the most common causes:

The diagnostic trouble code (DTC) specifically identifies an ABS Pump Motor Supply Voltage Circuit Short to Ground or Open within the vehicle's Anti-lock Braking System. When this electrical fault triggers, the Skid Control Computer logs the code, immediately illuminating the ABS dashboard warning light, and safely disables your automated braking features. Run a Bi-Directional Diagnostic Output Test If the

The root causes behind this error typically point to the electrical architecture driving the brake actuator assembly. 1. Blown High-Amp Fuses

Test for on the power delivery side to make sure the wire isn't bare and touching metal (short to ground). Step 4: Perform Module Initialization

As noted earlier, consult with the vehicle owner to determine if any aftermarket electrical components are or have been installed.

If you are skilled with soldering, you can open the ECU, remove the failed capacitors (usually 2-3 large electrolytic caps rated 470uF or 1000uF), and solder in new high-temperature, automotive-grade replacements. Check YouTube for "Toyota airbag ECU capacitor replacement." However, : SRS systems contain sensitive components; a poor solder joint could cause future failure.
