OBD II Monitor Information:

The table above summarizes the various OBDII monitors operation.

Global Good Trip Counter

For the most recent code (Code 1), the Global Good Trip counter counts the number of times the vehicle has started since it was last set. The Global Good Trip counter will count up to 3 Good Trips. After 3 Global Good Trips the counter will switch to a Warm Up Cycle Counter.

When there are no diagnostic trouble codes in memory, the DRBIII (R) will display "NO CODES FOUND" and the Global Good Trip counter will not be displayed.

The number of starts helps determine if the diagnostic trouble code is hard or intermittent.
- If the Global Good Trip count is displayed and equal to zero, the code is a hard code.
- If the Global Good Trip count is 3 or greater, it is considered an intermittent code and will switch to the Warm Up Cycle Counter. This means that the engine has been started most of the time without the code recurring.
- Freeze Frame - is the operating condition the vehicle was in, when the trouble code was set.

NOTE: Always check that "Frz F" caused by DTC" matches the code you are working on.
