READ DIAGNOSTIC TROUBLE CODE(S)

Normal Code Waveform:

Malfunction Code Waveform:

Read the 2-digit diagmostic trouble code as indicated by the number of times the SRS warning light blinks. As an example, of the blinking patterns; normal, 11 and 31 are as shown in the illustration.
1. Normal code indication
- The light will blink 2 times per second.
2. Malfunction code indication
- The number represented by the first blinking output indicates the first digit of a 2-digit diagnostic trouble code.
- After a 1.5 second pause, the 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 multiple trouble codes, indication will begin with the smallest numbered code first.
- If it does not output a diagnostic trouble code or output a diagnostic trouble code without terminal connection, proceed to the Tc terminal circuit inspection.
