1. CHECK FOR DTCs 
   1. Prepare the hand-held tester.
   2. Connect the hand-held tester to the DLC3 at the lower part of the instrument panel.
   3. Turn the power switch on (IG) and turn the hand-held tester on.
   4. Use the hand-held tester to check for DTCs and the freeze frame data, and note or print the result (see the operator's manual for operating instructions).
   5. See DIAGNOSTIC TROUBLE CODE CHART  to confirm the details of the DTCs.
2. CLEAR DTCs 

HINT:

The following procedures clear the DTCs and freeze frame data.

1. When using the hand-held tester:

   Operate the hand-held tester to clear the DTCs (see the operator's manual for operating instructions).

2. When not using the hand-held tester:

HINT:

Remove the P CON MAIN fuse to erase DTCs C2300, C2301, C2303, C2304, C2305, C2306, and C2307 because they cannot be erased with the hand-held tester.

3. Turn the power switch on (IG).

   FREEZE FRAME DATA 

5. The vehicle status, stored during system operation or at the time of an error code detection, can be displayed by the hand-held tester.
6. Only one record of freeze frame data is stored and the freeze frame data generated during system operation are updated whenever the vehicle status is changed. After storing the DTC, the freeze frame data is not updated.
