2003 Honda Pilot EXFACTORY OEM SERVICE PROCEDURE
EGR Monitor & Readiness Code: Procedure
- Connect the HDS or the scan tool to the vehicle's data link connector (DLC).
- Start the engine.
- Drive at a steady speed with the transmission in D position, 50-62 mph (80-100 km/h) or above for more than 10 seconds.
- With the transmission in D position, decelerate from 62 mph (100 km/h) or above by completely releasing the throttle for at least 5 seconds. If the engine is stopped during this procedure, go to step 3 and do the procedure again.
- If the readiness code is still set to incomplete, check for a temporary DTC. If there is no DTC, the enable criteria was probably not met; repeat the procedure.
