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

NOTE: Pay enough attention to the terminal connecting position as this will Cause a malfunction.

b. Past Troubles Codes:
Output the DTC.

1. Using service wire, connect terminals Tc and E1 of the DLC1.

2. Turn the ignition switch to the ACC or ON position and wait for approx. 20 seconds.

3. Using SST, connect terminals Tc and E1 of the DLC1.
SST 09843-18020

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






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 seconds pause, the second blinking output will indicate the second digit.






If there are 2 or more codes, there will be a 2.5 seconds pause between each code. After all the codes have been output, there will be a 4.0 seconds 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 inspection.
