DTC Check / Clear





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 to 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 to the correct positions 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 to the correct positions to avoid a malfunction.

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

(c) 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 to the left.

* Normal system code indication (without past trouble code):

* The light blinks twice per second.

* Normal system code indication (with past trouble code):

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

* Trouble code indication:

* The first blinking indicates the first DTC. The second blinking occurs after a 1.5 second pause.

(2) 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 then they all will be repeated.

HINT
* If 2 or more malfunctions are found, the indication begins with the smaller numbered code.
* If DTCs are indicated without connecting the terminals, proceed to the "TC and CG Terminal Circuit" procedures TC and CG Terminal Circuit.
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 to 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 comes on after 3 seconds.

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

(5) The SRS warning light should go 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 goes off.

(6) The SRS warning light comes on 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 comes on.

(7) Check if the SRS warning light goes off within 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 goes 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 to 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 to ON.

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

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