Reading and Clearing Diagnostic Trouble Codes

SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: DTC CHECK / CLEAR

1. CHECK DTC (USING SST CHECK WIRE)





(a) Check the DTCs (present trouble code).

(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.

SST : 09843-18040

NOTICE:
Connect the terminals correctly to avoid a malfunction.

(b) Check the DTCs (past trouble code).

(1) Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

SST : 09843-18040

NOTICE:
Connect the terminals correctly to avoid a malfunction.

(2) Turn the ignition switch ON and wait for approximately 60 seconds.

(c) Read the DTCs.





(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 the illustration.

* Normal system code indication (w/o past trouble code):

* The light blinks twice per second.

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

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

* DTC indication:

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

(1) 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.

2. CLEAR DTC (USING SST CHECK WIRE)

(a) Clear the DTCs.

(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.

SST : 09843-18040

(3) Disconnect terminal 13 (TC) of the DLC3 within 3 to 10 seconds after the DTCs are output, and check if the SRS warning light illuminates after 3 seconds.

(4) Within 2 to 4 seconds after the SRS warning light illuminates, connect terminals 13 (TC) and 4 (CG) of the DLC3.

(5) The SRS warning light 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 light turns off.

(6) The SRS warning light 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 light illuminates.

(7) Check if the SRS warning light 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 light turns off.

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





3. CHECK DTC (USING TECHSTREAM)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch ON.

(c) Check the DTCs by following the prompts on the Techstream screen.

HINT
Refer to the Techstream operator's manual for further details.

4. CLEAR DTC (USING TECHSTREAM)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch ON.

(c) Clear the DTCs by following the prompts on the Techstream screen.

HINT
Refer to the Techstream operator's manual for further details.
