DIAGNOSIS INSPECTION

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 or flashes, 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 Malfunction (Always lit up, when ignition switch is LOCK position.)".

DTC check

Using diagnosis check wire:





1. OUTPUT DTC
(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 DLC1 or DLC2.

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

2. READ DTC
Read the 2-digit DTC 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
The first blinking output indicates the first digit of a 2-digit DTC. After a 1.5 second pause, the second blinking output will indicate the second digit. If there are 2 or more codes, there will be a 2.5 second pause between each code. 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 start from the smallest numbered code to the larger.
- If it does not output a DTC or outputs a DTC without terminal connection, proceed to the Tc terminal circuit inspection.
