Diagnosis Inspection AIRBAG WARNING LIGHT CHECK (a) Turn the ignition switch to ACC or ON and check that the airbag warning light lights up. (b) Check that the airbag warning light goes out after approx. 6 seconds. HINT: • When the ignition switch is at ACC or ON and the airbag warning light remains on, the center airbag sensor assembly has detected a malfunction code. • If, after approx. 6 seconds have elapsed, the airbag warning light sometimes lights up or the airbag warning light lights up even when the ignition switch is at OFF, a malfunction in the airbag circuit can be considered likely. Proceed to ''Airbag warning light system (always lit up)'' on page AB-75. DIAGNOSTIC CODE CHECK 1. OUTPUT DIAGNOSTIC 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 check connector. SST 09843-18020 NOTICE: Never make a mistake with the terminal connection position as this will cause a malfunction. 2. READ DIAGNOSTIC CODE Read the diagnostic code as indicated by the number of times the airbag warning light blinks. • 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 first number of the code No. will equal the first digit of a 2-digit diagnostic code, and after a 1.5 second pause, the 2nd number of the code No. will equal the 2nd 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 second pause 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 a diagnostic code is not output or is continuously output, proceed to the Tc terminal circuit inspection on page AB-77.
