How to Run Tests, Read and Extract Codes

Fig. 4 Self-diagnosis output patterns & output codes:

Self-diagnosis output patterns (voltage signals generated at the self-diagnosis check connector) are patterns shown as wave forms, Fig. 4. The voltage signal or wave forms are indicated by changes in the range of 0 to 12 volts. These readings help determine each malfunction condition of the automatic level control system.
