HINT: The illustration of connector shown below represents other illustrations. Though the shapes of some connectors are different, terminals alignment is same.

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 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 circuit malfunction."

DTC CHECK (Using diagnosis check wire)
(a) Present Trouble Codes:
Output the DTC.
(1) Turn the ignition switch to the ACC or ON posit and wait approx. 20 seconds.





(2) Using SST, connect terminals Tc and E1 of the DLC1.
SST 09843-18020

NOTICE: Pay enough attention to the terminal connecting position as this will cause a malfunction.

(b) Past Trouble Codes:
Output the DTC
(1) Using service wire, connect Terminals Tc and E1 on the DLC1.
(2) Turn the ignition switch to the ACC or ON position and wait approx. 20 seconds.
(3) Using SST, connect terminals Tc and E1 of the DLC1.
SST 09843-18020

NOTICE: Pay enough attention to the terminal connecting position as this will cause a malfunction.

Normal Code:

Code 11 And 31:

(c) 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, B0102/11 and B1100/31 are as shown in 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.
- It a DTC is not output or a DTC is output without terminal connection, proceed to the Tc terminal circuit inspection.
