Reset Counter

The reset counter counts the number of times the vehicle has been started since codes were last set, erased, or the battery was disconnected. The reset counter will count up to 255 start counts.

The number of starts helps determine when the trouble code actually happened. This is recorded by the PCM and can be viewed on the DRBIII as STARTS since set.

When there are no trouble codes stored in memory, the DRBIII will display "NO DTC'S Detected" and the reset counter will show "STARTS since clear = XXX."
