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 and 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 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 battery terminal, perform
the "INITIALIZATION" procedure (see page AX-
18).
