OK -- Continue to next step.

5. 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.

(a) Turn the engine switch off.

(b) Reconnect the skid control ECU connector.

(c) Clear the DTCs See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and

Clearing Diagnostic Trouble Codes.

(d) Start the engine.

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

(f) Check if the same DTC is recorded See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and

Inspection/Reading and Clearing Diagnostic Trouble Codes.

Result:

HINT

- If a speed signal of 6 km/h (4 mph) or more is input to the skid control ECU with the engine switch on (IG) and the stop light

switch off, the ECU performs self diagnosis of the motor and solenoid circuits.

- If the normal system code is output (no trouble codes are output), slightly jiggle the connectors, wire harness, 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 assembly (skid control ECU), inspect

and repair the connector or wire harness.

- It is suspected that the DTCs were output due to a bad connection of the connector terminal.
