DTC CHECKUsing diagnosis check wire:
1. OUTPUT DTC
(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. SST 09843-18020
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 to the larger.
- If it does not output a DTC or outputs a DTC without terminal connection, proceed to the Tc terminal circuit inspection.
