REPLACE BRAKE ACTUATOR ASSEMBLY

RECONFIRM DTC

HINT:

This code is detected when a problem is identified in the brake actuator assembly.

The ABS motor relay is in the brake actuator assembly. Therefore, ABS motor relay inspection and motor relay unit inspection cannot be performed. Be sure to check if the DTC is output before replacing the brake actuator assembly.

(b) Start the engine.

(c) Drive the vehicle at the speed of 12 mph (20 km/h) or more for 30 seconds or more.

(d) Check that the same DTC is recorded.

DTC is not output

A

DTC is output

• If the normal system code is output (the malfunction code is not output), slightly jiggle the connectors, wire harnesses, and fuses of the brake actuator assembly. Make sure that no DTCs are output.

• If any DTCs are output while jiggling a connector or wire harness of the brake actuator (skid control ECU), inspect and repair the connector or wire harness.

• These DTCs may be stored due to a malfunction in the connector terminal connection, etc.
