DTC CHECK

Using diagnosis check wire:

1. OUTPUT DIAGNOSTIC TROUBLE CODE

(a) Turn the ignition switch to ACC or ON position and wait approx. 20 seconds.
(b) Using SST, connect terminals Tc and E1 of the DLC1.

HINT: DTC check and troubleshooting of each DTC can also be done using DLC2.

NOTICE: Never make a mistake with the terminal connection position as this will cause a malfunction.

2. 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, 11 and 31 are as shown on 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 it does not output a DTC or outputs a DTC without terminal connection, Refer to the Tc terminal circuit.TC Terminal Circuit
