RETRIEVING DIAGNOSTIC TROUBLE CODES

1. SRS WARNING LIGHT CHECK





(a) Turn the ignition switch to the ACC or ON position 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."

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





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

NOTICE: Pay due attention to the terminal connecting position to avoid a malfunction.

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

NOTICE: Pay due attention to the terminal connecting position to avoid a malfunction.

Codes 11 And 31:

Normal Code:

(c) Read the 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 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.
- If a DTC is not output or a DTC is output without terminal connection, proceed to the "Tc Terminal Circuit."
