NOTE:
Before generating readiness code, perform a long road test. Coolant temperature needs to be greater than 176° F (80° C). Idle, partial throttle, full throttle and overdrive, all must be attained several times. During test drive, apply full throttle until engine speed exceeds 3500 RPM. Read readiness code. OBD system checks components and generates Readiness Code at regular intervals during normal driving.
