NOTICE: When the diagnostic system is switched from normal mode to check mode, all the DTCs and freeze frame data recorded in normal mode are erased. So before switching modes, always check the DTCs and freeze frame data, and note them down.
(a) Check DTCs using an intelligent tester.
(1) Turn the ignition switch off.
(2) Connect the intelligent tester to the DLC3.
(3) Turn the ignition switch to the ON position and turn the intelligent tester main switch on.
(4) Select the following items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
(5) Read the DTCs and freeze frame data displayed on the tester and note them down.
NOTICE: When simulating symptoms with an intelligent tester to check the DTCs, use normal mode. For DTCs in the DTC chart, which are subject to 2-trip detection logic, perform the following.
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.
