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 Seconds 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.
