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

NOTE: 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

NOTE: 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 trouble codes 11 and 31 are shown in the illustration.
- 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 blink indicates the first DTC. The second blinks occurs after a 1.5-second pause.
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 all codes 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 "Diagnosis Circuit" Component Tests and General Diagnostics.

2. CLEAR DTC (Using SST Check Wire)
(a) When the ignition switch is turned off, the DTCs are cleared.

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

(b) Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3, and then turn the ignition switch to ON.
SST: 09843-18040
(c) Disconnect terminal 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.
(d) Within 2 to 4 seconds after the SRS warning light comes on, connect terminals 13 (TC) and 4 (CG) of the DLC3.
(e) 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.
(f) 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.
(g) 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) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / SRS Airbag / Trouble Codes /
4. CLEAR DTC (Using Techstream)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / SRS Airbag / Trouble Codes /
(e) Clear the DTCs.
