HINT:
• Reinstall the sensors, connectors, etc. and restore the
vehicle to its prior condition before rechecking for
DTCs.
• If a speed signal of 6 km/h (4 mph) or more is input to
the skid control ECU, with the ignition switch on and
the stop light switch off, the ECU performs self-
diagnosis of the motor and solenoid circuits.

HINT:
• 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.
• If the normal system code is output, slightly jiggle the
connectors, wire harnesses, and fuses of the brake
actuator assembly. Make sure that no DTCs are
output.
• These DTCs may be stored due to a malfunction in
the connector terminal connection, etc.
