DTC CHECK / CLEAR
1. CHECK DTC
DTCs which are stored in the ECM can be displayed with the
hand−held tester or generic OBD II scan tool.
These scan tools can display pending DTCs and current DTCs.
Some DTC aren't stored if the ECM doesn't detect a malfunc-
tion during consecutive driving. However, the detected mal-
function during once driving is stored as pending DTC.
(a) Connect the hand−held tester to the Controller Area Net-
work Vehicle Interface Module (CAN VIM). Then connect
the CAN VIM to the Data Link Connector 3 (DLC3).
(b) Turn the ignition switch ON.
(c) Enter the following menus: DIAGNOSIS / ENHANCED
OBD II / DTC INFO / CURRENT CODES (or PENDING
CODE).
(d) Confirm the DTCs and freeze frame data and then write
them down.
(e) See page DI−1156
NOTICE:
When simulating a symptom with the scan tool to check for
DTCs, use normal mode. For codes on DIAGNOSTIC
TROUBLE CODE CHART subject to "2−trip detection log-
ic", perform the following actions.
Turn the ignition switch OFF after the symptom is simulated
once. Then repeat the simulation process again. When the
problem has been simulated twice, the MIL illuminates and the
DTCs are recorded in the ECM.
2. CLEAR DTC
(a) Connect the hand−held tester to the CAN VIM. Then con-
nect the CAN VIM to the DLC3.
(b) Turn the ignition switch ON.
(c) Enter the following menus: DIAGNOSIS / ENHANCED
OBD II / DTC INFO / CLEAR CODES and press YES.
to confirm the details of the DTCs.
