Reading Readiness Code

NOTE: Before reading 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, must all be attained several times. During test drive, apply full throttle until engine speed exceeds 3500 RPM. OBD system checks components and generates Readiness Code at regular intervals during normal driving, see GENERATING READINESS CODE . Readiness code is erased if DTC memory is erased or voltage supply to ECM is lost.
