CHECK DTC

Using SST (diagnosis check wire No. 2):

CHECK DTC

a. Present troubles codes:
Output the DTC.




1. Turn the ignition switch ON, and wait for approx. 20 seconds.
2. Using SST, connect terminals Tc and CG of the DLC3.
SST 09843-18040

NOTE: 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 CG of the DLC3.
SST 09843-18040

2. Turn the ignition switch ON, 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.
