Toyota RAV4 Service Manual: Dtc check / clear

1. Check dtc

1. Dtcs which are stored in the ecm can be displayed with the intelligent tester.

   The intelligent tester can display pending dtcs and current dtcs. Some dtcs are not stored unless a malfunction is detected in consecutive driving cycles. When a malfunction is detected in only one driving cycle, it is stored as a pending dtc.

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 / current codes (or pending code).
4. Confirm the dtcs and freeze frame data and then write them down.
5. Confirm the details of the dtcs (see page ax- 35).

Notice:

When simulating a symptom with the scan tool to check for dtcs, use normal mode.

Turn the ignition switch off after the symptom is simulated once. Then repeat the simulation process again. When the symptom has been simulated twice, the mil illuminates and the dtcs are recorded in the ecm.
