DTC Check/Clear

1. Turn the ignition switch ON and wait for approximately 60 seconds.
2. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

   NOTE: Connect the terminals to the correct positions to avoid a malfunction.
2. Turn the ignition switch ON and wait for approximately 60 seconds.

1. Read the blinking patterns of the DTCs. Examples of the blinking patterns for the normal system code and DTCs 11 and 31 are shown in Fig 2.
   • Normal system code indication (w/o past trouble code):

     The lamp blinks twice per second.

   • Normal system code indication (w/ past trouble code):

     When the past trouble code is stored in the airbag sensor center, the lamp blinks once per second.

   • DTC indication:

     For DTC 11, the lamp illuminates for 0.5 seconds, turns off for 1.5 seconds, and then illuminates again for 0.5 seconds.

     If there is more than 1 code, there will be a 2.5 second pause between each code. After all codes are shown, there will be a 4.0 second pause, and all codes will be repeated.

HINT:

• If 2 or more malfunctions are detected, the indication begins with the smaller numbered code.

1. When the ignition switch is turned OFF, the DTCs are cleared.

   HINT:

   Depending on the DTC, the code may not be cleared by turning OFF the ignition switch. In this case, proceed to the next procedure.

2. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3, and then turn the ignition switch ON.

3. Disconnect terminal TC of the DLC3 within 3 to 10 seconds after the DTCs are output, and check if the SRS warning lamp illuminates after 3 seconds.
4. Within 2 to 4 seconds after the SRS warning lamp illuminates, connect terminals 13 (TC) and 4 (CG) of the DLC3.
5. The SRS warning lamp should turn off within 2 to 4 seconds after connecting terminals 13 (TC) and 4 (CG) of the DLC3. Then, disconnect terminal 13 (TC) within 2 to 4 seconds after the SRS warning lamp turns off.
6. The SRS warning lamp illuminates again within 2 to 4 seconds after disconnecting terminal 13 (TC). Then, reconnect terminals 13 (TC) and 4 (CG) within 2 to 4 seconds after the SRS warning lamp illuminates, connect terminals 13 (TC) and 4 (CG) of the DLC3.
7. Check if the SRS warning lamp turns off 2 to 4 seconds after connecting terminals 13 (TC) and 4 (CG) of the DLC3. Also check if the normal system code is output within 1 second after the SRS warning lamp turns off.

   If DTCs are not cleared, repeat this procedure until the codes are cleared.
