This PI was superseded to advise dealers there is no repair for early oil change messages or erratic OlM operation. Please discard PIP4540B. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition I Concern: A dealer may encounter a customer concern of the oil life monitor (OlM) percentage dropping too qUickly, or an early oil change message. A customer utilizing the oil life monitor may be directed to change the oil at (or near) 1000 mile intervals. Recommendation Ilnstructions: Please do not replace the IPC or ECM for an early oil change message. Oil life monitoring is dependent on vehicle use. Oil life monitoring and change intervals will differ depending on how the vehicle is driven. Please complete the current SI diagnostics for any trouble code or symptom found. Engine drivability concerns may induce early oil change messages or erratic OlM operation. Dealers should verify there are no intake or exhaust leaks by completing Charge Air Cooler Diagnosis (Full System Air leak Test and the Induction System Smoke Test). Discuss driving habits with the customer. The main contributor to early or erratic oil change messages may be some of the customers driving habits. Drive cycles that include short trip, stop and go, and extended idle times are a few of the contributors to early oil change messages. Customers with more exhaust regenerations (due to driving habits) are more susceptible to qUicker oil change messages. There is no repair for early oil change messages or erratic OlM operation. If a dealer is to encounter a vehicle with a customer concern of early oil change complete a Field Product Report using the newest version of bulletin 02-00-89-002. Note: If an oil analysis has been completed fuel dilution should not be over 12%.

DESCRIPTION
When the engine is first started, some vehicles may exhibit a loud ticking noise from the variable valve timing
(VVT). This is caused by the lock pin of the variable valve timing actuator not fully engaging. Heat treatment has
now been added around the hole of the variable valve timing rotor lock pin to prevent this from happening
