General Recommendations

Most monitors will complete easier and quicker using a "steady-foot" and "smooth" acceleration during the drive cycle operation, cruise, and acceleration modes.

Operating conditions

For the EVAP monitor test, the coolant temperature and the ambient air temperature must be between 10°C and 35°C with a difference between them no greater than 4°C. The ambient air temperature must not change more than 4°C during the drive cycle procedure (e.g. when driving out of a heated workshop in the winter).
