SRS Warning Light Check:
(a) Turn the ignition switch to ACC or ON and check that the SRS warning light lights up.
(b) Check that the SRS warning light goes out after approx. 6 seconds.

HINT:
- When the ignition switch is at ACC or ON and the SRS warning light remains on, the center airbag sensor assembly has detected a malfunction code.
- If, after approx. 6 seconds have elapsed, the SRS warning light sometimes lights up or the SRS warning light lights up even when the ignition switch is OFF, a short in the SRS warning light circuit can be considered likely. Proceed to SRS warning light system (always lit up when ignition switch LOCK position).





Diagnostic Trouble Code Check Using Diagnosis Check Wire:
1. Output Diagnostic Trouble Code
(a) Turn the ignition switch to ACC or ON position and wait approx. 20 seconds.
(b) Using SST, connect terminals Tc and E1 of the DLC2. SST 09843-18020

NOTICE: Never make a mistake with the terminal connection position as this will cause a malfunction.

2. Read Diagnostic Trouble Code
Read the 2-digit diagnostic trouble code as indicated by the number of times the SRS warning light blinks. As an example, the blinking patterns; normal, 11 and 31 are as shown on the illustration.





- Normal code indication
The light will blink 2 times per second.





- Malfunction code indication
In the event of a malfunction, the light will blink. The number represented by the first blink code output indicates the first digit of a 2-digit diagnostic trouble code. After a 1.5 second pause, the second blink code will indicate the second digit.
If there are two or more codes, there will be a 2.5 second pause between each.
After all the codes have been output, there will be a 4.0 secondpause and they will all be repeated.

HINT:
- In the event of a number of trouble codes, indication will begin from the smaller numbered code to the larger.
- If it does not output a diagnostic trouble code or output a diagnostic trouble code without terminal connection, proceed to the Tc terminal circuit inspection.
