DTC Check / Clear

CHECK DTC (USING SST CHECK WIRE)
1. Check for DTCs (Present DTC).
  1. Turn the power switch ON (IG), 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. Check for DTCs (Past DTC).
  1. 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 power switch ON (IG), and wait for approximately 60 seconds.
3. Read the DTCs.
  1. Read the blinking patterns of the DTCs. As examples, the blinking patterns for the normal system code and DTCs 11 and 31 are shown in the illustration.
    - Normal system code indication (without past DTC)
      The light blinks twice per second.
    - Normal system code indication (with past DTC)
      When the past DTC is stored in the center airbag sensor, the light blinks once per second.
    - DTC indication
      The first blinking pattern indicates the first digit DTC. The second blinking pattern occurs after a 1.5-second pause.
    If there are 2 or more DTCs, there is a 2.5-second pause between each DTC. After all DTCs are shown, there is a 4.0-second pause, and they are all repeated.
    
    HINT:
    - If 2 or more malfunctions are found, the indication begins with the lowest numbered DTC.
    - If DTCs are indicated without connecting the terminals, proceed to the "TC AND CG TERMINAL CIRCUIT " .

CLEAR DTC (USING SST CHECK WIRE)
1. Clear the DTCs.
  1. When the power switch is turned OFF, the DTCs are cleared.
    HINT:
    
    Depending on the DTCs, the DTCs may not all be cleared by turning off the power switch. In this case, proceed to the next step.
  2. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3, and then turn the power switch on.

  3. Disconnect terminal 13 (TC) of the DLC3 within 3 to 10 seconds after the DTCs are output, and check that the SRS warning light comes on after 3 seconds.
  4. Within 2 to 4 seconds of the SRS warning light coming on, connect terminals 13 (TC) and 4 (CG) of the DLC3.
  5. The SRS warning light goes off within 2 to 4 seconds of connecting terminals 13 (TC) and 4 (CG) of the DLC3. Then, disconnect terminal 13 (TC). within 2 to 4 seconds of the SRS warning light going off.
  6. The SRS warning light comes on again within 2 to 4 seconds of disconnecting terminal 13 (TC). Then, reconnect terminals 13 (TC) and 4 (CG) within 2 to 4 seconds of the SRS warning light coming on.
  7. Check that the SRS warning light goes off within 2 to 4 seconds of connecting terminals 13 (TC) and 4 (CG) of the DLC3. Also check that the normal system code is output within 1 second of the SRS warning light going off.
    If DTCs are not cleared, repeat these procedure until the DTCs are cleared.

CHECK DTC (USING INTELLIGENT TESTER)
1. Connect the intelligent tester (with CAN VIM) to the DLC3.
2. Turn the power switch ON (IG).
3. Check the DTCs by following the prompts on the tester screen.
  HINT:
  
  Refer to the intelligent tester operator's manual for further details.

CLEAR DTC (USING INTELLIGENT TESTER)
1. Connect the intelligent tester (with CAN VIM) to the DLC3.
2. Turn the power switch ON (IG).
3. Clear the DTCs by following the prompts on the tester screen.
  HINT:
  
  Refer to the intelligent tester operator's manual for further details.
