Fuel system monitor incomplete code#

at one point on the highway I tried to turn on cruise control and accidentally hit my turn signal. Passed hours later when I took it to the shop. One I got below 20mph, I went back to normal driving and went home. I held 55 again for 6 minutes and then did the decelerate to 20 mph again without breaking. as soon as the car went below 20 mph, I then accelerated back up to 55mph without exceeding 3,000rpm. When the car hits 20mph on the way down, you feel a gear shift that I think is what the system is looking for. At 4 minute mark, turned on emergency lights and let off gas without touching break all the way past 20mph. when I got to the highway, I accelerated somewhat slowly up to 55 and held at 55 for 4 minutes (longer than 3 but had cars behind me so didn't feel safe to decelerate). I did have to break a few times, but at no point did I exceed 40mph or 3,000rpm. I then put the car in drive and made my way to the highway, which took about 3 minutes. at the 2.5 minute mark, I turned off the Ac, radio, and defroster and backed out of my garage. I have an automatic 2010 BMW 328i and failed smog twice prior to doing this: -Cold started my car at about 6 am and turned AC, Defroster, and radio on. I used these instructions with some variations this morning and passed my smog check hours later, so I thought I'd come back and give my experience in case it helps anyone else.

The Driving Cycle performs a diagnostic test on all the systems that the computer monitors. You will need to do a Driving Cycle if you have replaced the battery, disconnected the battery, or cleared the codes after a repair. OBD-II Driving Cycle: If you have a 1996-up BMW, you have the OBD-II diagnostic system that constantly monitors the sensors and solenoids on the engine. Both of these methods are extremely time consuming but there is another way to get the OBC ready to pass the smog check. You could either drive a whole 200 miles hopefully the OBC is ready or do as BMW dealership had suggested to drive 30 miles, park the car in idle for 30 minutes, and repeat this process for at least 3-4 times. This process can be either cost consuming or time consuming. In order for your car to pass the smog check, you need to do a drive cycle to get the OBC ready. This makes the car not ready for a smog check. I can email it to anyone who asks.Why do I need to do a drive cycle? If you have recently changed the battery on your BMW or done a major repair for the engine or emission system, the on board computer has mostly been reset. doc file with screenshots but can't figure any way of attaching it. Thoughts, experiences and comments welcomed. The car just crossed 40K miles so I want to make sure that I get it to the dealer if necessary before the warranty runs out. Will they eventually clear themselves or am I up against another issue?

Fuel system monitor incomplete code#

I just cleared the latest underboost code from a limp mode fault three days ago. I was under the impression that Readiness codes would clear themselves given time. It only does this first thing in the morning going uphill from my driveway. The monitor executes continuously under normal engine operating and driving conditions providing there are no. It also infrequently goes into limp mode for underboost(16683). The fuel system monitor allows the PCM to evaluate how close the fuel control system can regulate the fuel mixture in attempting to achieve an optimum air/fuel ratio in the combustion chamber throughout varying engine rpm and load ranges. Sorry for all the data I don't know what is and is not important. MIL off - all 3 sections Failed or Incomplete. The Previous Address 1A is clearly engine related, not Transmission. OBDII Mode 3 reports Address 10 (Engine): No Faults and Address 1A (Auto Trans): No Faults.
