HINT:
DTC will be output when conditions for any of the patterns in the table above are met.
INSPECTION PROCEDURE
NOTICE:
When replacing the skid control ECU (brake actuator assembly), perform zero point calibration and store
system information .
PROCEDURE
1. RECONFIRM DTC
HINT:
These codes are detected when a problem is determined in the skid control ECU (brake actuator assembly).
The solenoid circuits are in the skid control ECU (brake actuator assembly).
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if
any DTCs are output before replacing the skid control ECU (brake actuator assembly).
(a) Clear the DTC .
(b) Turn the ignition switch off.
(c) Start the engine.
(d) Drive the vehicle at a speed of 20 km/h (12 mph) or more for 30 seconds or more.
(e) Check if the same DTC is recorded .

RESULT PROCEED TO
DTC is not output A
DTC is output B
HINT:
If a speed signal of 6 km/h (4 mph) or more is input to the skid control ECU (brake actuator assembly),
with the ignition switch to ON and the stop light switch off, the ECU performs self diagnosis of the motor
and solenoid circuits.
If the normal system code is output (the trouble code is not output), slightly jiggle the connectors, wire
harness, and fuses of the skid control ECU (brake actuator assembly). Make sure that no DTCs are output.
If any DTCs are output while jiggling a connector or wire harness from the skid control ECU (brake actuator
assembly), inspect and repair the connector or wire harness.
The DTCs were probably output due to a bad connection of the connector terminal.
