DTC CHECK (Using diagnosis check wire)




a. Present troubles codes:
Output the DTC.

1. Turn the ignition switch to the ON position and wait for approx. 20 seconds.
2. Using SST, connect terminals Tc and CG of the DLC3.
SST 09843-18020

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

b. Past troubles codes:
Output the DTC.

1. Using service wire, connect terminals Tc and CG of the DLC3.
SST 09843-18020

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

NOTE: Pay due attention to the terminal connecting position to avoid 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-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 inspection.
