Turn the ignition switch OFF after the
symptom is simulated once. Then repeat the
simulation process. When the symptom has
been simulated twice, the MIL illuminates
and the DTCs are recorded in the ECM.
2. CLEAR DTC
(a) When using the intelligent tester:
(1) Connect the intelligent tester to the CAN VIM.
Then connect the CAN VIM to the DLC3.
(2) Turn the ignition switch ON and turn the tester
ON.
(3) Enter the following menus: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CLEAR
CODES. Then press YES.
HINT:
When operating the tester to erase the codes,
the DTCs and freeze frame data will be erased.
(b) When not using the intelligent tester:
(1) Disconnect the cable from the negative (-)
battery terminal or remove the EFI MAIN and
ETCS fuses from the engine room No. 1 relay
block and engine room No. 1 junction block for
60 seconds or more. However, if you disconnect
the cable from the negative (-) battery terminal,
perform the "INITIALIZATION" procedure (see
page AX-20).
