AX
(11)(See page AX-35) to confirm the details of the
DTCs.
2. DTC CLEAR
(a) When using the OBD II scan tool or intelligent
tester: Clearing the DTCs.
(1) Connect the intelligent tester together with the
CAN VIM (controller area network vehicle
interface module) to the DLC3.
(2) Turn the ignition switch to the ON position and
turn the OBD II scan tool or the intelligent tester
main switch on.
(3) When you use intelligent tester: Select the item
"DIAGNOSIS/ENHANCED OBD II/DTC INFO/
CLEAR CODES [YES] button".
HINT:
When operating the OBD II scan tool (complying
with SAE J1978) or intelligent tester to erase the
codes, the DTCs and freeze frame data will be
erased. (See the OBD II scan tool's instruction
book for operating instructions.)
(b) When not using the OBD II scan tool or intelligent
tester: Clearing the DTCs.
(1) Disconnect the battery cable or remove the EFI
and ETCS fuses from the engine room J/B for 60
seconds or more. However, if you disconnect the
battery cable, perform do the "INITIALIZE"
procedure.

BC–32BRAKE CONTROL – ANTI-LOCK BRAKE SYSTEM
BC
(a) Clear the DTCs (See page BC-10).
(b) Start the engine.
(c) Drive the vehicle at the speed of 4 mph (6 km/h) or more.
(d) Check that the same DTCs are recorded (See page BC-
10).
HINT:
If a speed signal of 4 mph (6 km/h) 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.
Result
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.
