Continuity and Out-of-Range Value Check

Continuity and out-or-range value check:
This diagnosis detects open circuit or short-circuiting in the Electronic Spark Timing (EST) line by monitoring EST signals. A failure determination is made when the signal voltage remains higher or lower than the threshold for corresponding fault code beyond a predetermined time period.




Diagnosis enabling conditions are as follows:
- RPM is higher than the specified threshold.
- EST line is enabled.
