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 21 are shown in the illustration to the above.
   

   1. Normal system code indication (without past trouble code):
      
   1. w/o Multi information display:
      The SRS warning light blinks twice per second.
      
   2. w/ Multi information display:
      "FF" is displayed on the multi information display.
      
   2. Normal system code indication (with past trouble code):
      
   1. w/o Multi information display:
      When the past trouble code is stored in the center airbag sensor, the light blinks only once per second.
      
   2. w/ Multi information display:
      "FF" is displayed on the multi information display.
      
   3. Trouble code indication:
      
   1. w/o Multi information display:
      The first blinking indicates the first DTC. The second blinking occurs after a 1.5 second pause.
      
   1. w/ Multi information display:
      A DTC is displayed on the multi information display.
      
   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:

   1. If 2 or more malfunctions are found, the indication begins with the smaller numbered code.
      
   2. If DTCs are indicated without connecting the terminals, proceed to the "TC and CG Terminal Circuit" procedures (RAV4_ACA30 RM000000XFB01UX.html).
      

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 (IG).

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.
