It was also accompanied by a check engine lamp on, with a code P0505, or Idle Air Control System Malfunction. The repair shop performed a throttle body cleaning and replaced the spark plugs, which were severely worn out. They also tested and replaced the throttle position sensor, but none of these measures solved the problem. The erratic idle continued, and it was then that the shop decided to call me in for assistance. I started my diagnostics by scanning the vehicle's ECM, and see what it perceived. A scan tool, is a window into the ECM, and sure enough, code P0 505 came to view. Ok, this was expected and not out of the ordinary. I then decided to perform a bi-directional control of the idle control valve, which was a fully motorized unit, using 4 coil windings. As I performed the bi-directional control, nothing happened. The valve was totally out, either due to the ECM, not commanding or the valve itself. The bi-directional control forces the ECM into performing an action. My next diagnostic path was to grab a multi meter, or in my case, a graphing multi meter and test for idle control valve resistance. I removed the I A C valve, and checked for more than 20 Ohms resistance. If they were, them the idle control valve was shorted. All four coils on the I A C valve tested fine, so I next easily re-installed the valve. My next move was to check the command signal to the IAC valve. I connected the graphing meter to the coil output, and using the scan tool, commanded the idle control valve to a higher and lower percentage. As I did that, I saw no change in the graphing multi meter. Ok good, so my issue was at the command wires, or the ECM was not actuating the IAC valve. I was getting close to the problem. I reasoned, that the issue was probably ..... Get the whole story right now!..... Watch this video and learn what happened next!.... Watch and learn....

For some reason, the shop replaced the crank sensor. Because is was a no start, they reason it was probably the crank sensor, and of course, it wasn't. They eventually saw the security light on, and figured out that it was a Pass-Lock system issue. They next replaced the Pass-Lock key cylinder, with no luck either. At this time, the shop decided to call me in for assistance. They simply didn't have to scan tool to access the BCM or body module for this problem. When I arrived at the shop, the tech gave me a briefing on the vehicle, and also said that the vehicle would start once in a blue moon. Ok, that was probably some kind of clue. I started my diagnostic by performing a general code analysis. I did get code P1632, or Theft Deterrent Fuel Disable Signal Received from the BCM. There were no other codes present. I knew it wasn't the key cylinder, since it was already replaced. There are steps to take in all Pass Lock diagnostics before condemning a component. In this particular GM, the signal from the ignition system is controlled by a resistor embedded in the Pass Lock module, which is part of the ignition switch cylinder. In these systems, any key that will allow the cylinder to be turned to the on position will work, the only condition that must be met is that the cylinder must be turned to a position where a magnet engages a hall effect switch, which connects the embedded resistor to the system, allowing the Body Control Module to read the signal value, on the yellow Pin A6 wire, and determine if the resistance value is correct. I analyzed the Pass Lock calibration and determined that it was correct. So, why was this car not starting? I started to suspect an electrical or connector fault. So I decided to visually inspect the Pass Lock module and wiring. Everything looked normal, so I then decided to concentrate on the BCM. As I scanned the B C M data stream for clues, I saw that all of a sudden I lost communications. Was the ECM defective? Or, was it an issue with the ......

The shop also scanned the vehicle and obtained a series of O2 sensor codes. A basic tune up was performed, including the spark plugs and wires. Then, the front O2 sensors were also replaced. But neither of these repairs corrected the problem. The codes were erased, the vehicle was driven and the same codes came back again. The tech did say that the valve cover gaskets were replaced due to an oil leak, which might have damaged the O2 sensors. I took that with a grain of salt. When I got to the shop, I immediately started my diagnosis plan by scanning the E C M. Sure enough, there were O2 sensor codes present and the perennial P0172 and P0175 or fuel system too rich. A rich condition is a bit more rare than a lean one. More issues are related to lean conditions, not rich. But this was the opposite. So I started thinking what would drive the mixture rich, like a plugged fuel regulator return, leaky injector, and excess fuel in the oil or even a blown head gasket. But, these were wide areas of concern, and I only had an hour for diagnostics time. I needed to sharpen my Robo Tech strategy! What is the fastest way to determine mixture? It was either a 5-gas analyzer or using the O2 sensors. I decided to go with the oscilloscope and the O2 sensors, since the 5-gas took longer to set up. The O2 sensors were brand new, so I knew there were good. I proceeded to connect channel 1 of the scope to the O2 sensor's signal wire. I did find something curious. It seemed that the valve cover gasket was leaking again, because I found the O2 sensor wires oil soaked. I checked for oil leaks at the valve covers, but found none. What was going on here? Could it be that the ..... What happened next?..... Get the whole story right now!.... Watch the entire story right here in this video right now!.....

The engine had a slight misfire upon acceleration, and during a pre-loaded condition. During idle, the engine tended to stay fairly smooth, and ran fine. The shop did not engaged in parts changing, and went through all the steps of checking the issue. The shop did replace the spark pugs, but did not have an ignition scope to properly check the high voltage waveform. This engine was a coil on plug or COP unit, which makes it hard to check ignition. After trying without any success on finding the problem, the shop decided to call me in for assistance. When I got to the shop, the first impulse was to grab the ignition scope, but I am Robo Tech, I knew better, and stuck to proper procedure. I started my diagnostics by using the scan tool to check codes, and do a data stream analysis. I retrieved code P0303, exactly as stated by the tech. I then did a fuel trim analysis, and found that, at idle, the air fuel mixture was stable and holding at about plus to minus 4%. Then, while in gear and pre loading the engine, fuel trims went to positive 20%. This was an indication of a lean condition or a misfiring cylinder. A misfiring cylinder dumps raw fuel into the Exhaust. Incredible as it may seem, the O2 sensor senses this as a lean condition, since it doesn't care about fuel, and only sees the Oxygen content in the Exhaust. At this time, I was ready to perform an ignition check, using my portable engine analyzer. This was a tough engine to do, since it had coil on plug, and everything was hidden. But, I had in my possession a capacitive pick up system to capture ignition patterns over the air, with no need for disassembly. This equipment consisted of an amplifier box unit, to amplify the signal, a series of capacitive pick up antennas seen here in green, and the synch probe to set the signal to a specific cylinder. The unit was easy to set up. The amplifier box connected straight to my scope, and had a gain knob to fine tune the output. As soon as I did the test, I saw a good waveform at idling speeds. Then, as I did a wide open throttle goose test, I immediately saw the problem. On both, the wide open throttle and a pre loaded test, cylinder number 3 was missing. I could also see that in the ignition pattern indicated that there was plenty of kilo volts present. So, the coil was probably in good condition. All I had to do now was figure out one thing. Was I having a fuel misfire, or an ignition misfire due to a faulty coil boot arching at the spark plug hole? I then decided to pull out an old diagnostic technique. I wanted to do the ....

GM Passkey Bypass VATS (PART 1)
Prep work on what you will need to properly perform the Passkey Bypass for the GM VATS. (PART 1) ...Good Luck!! Please scan OBD-II for DTC P1626 (Theft Deterrent Fuel Enable Signal Lost) prior to starting this project if possible. I am not responsible for any damage if you screw up or perform this needlessly **cheers**

VATS bypass, partial LS1
Fixing (bypassing) my BCM since VATS decided to act up, all that's left is a bypass module and hopefully that will fix things. The BCM sends a 30 or 50hz signal to the PCM telling it to give fuel to the engine, as well as ground the starter solenoid. What I've done here is ground the starter solenoid, so it will start...just runs out of fuel after 2 seconds or so.

Why GM's PassLock blows ! Stupid body control module thinks I'm trying to steal my own truck.

Successful 1994 Camaro Hotwire
It started just like any other Monday, the work routine, the feeding of various pets, the sifting through piles of junk mail and ceaseless bills, and what would have been the all-too-often trip to Walmart. But that fateful evening would not be like those that preceded it. No, instead my Camaro ignition would literally FALL APART right there in my hand. Why? Who knows. If a problem arises with this car anymore, I rather ask "Why not?" So I priced a new ignition lock at O'Reilly Auto Parts (don't) and decided in anger to proceed with the total destruction of my impenetrable steering column. Behind the airbag (disconnect first or die), and behind the airbag spring assembly, and behind the turn signal assembly, and behind the wheel lock plate (it really does come off, I promise), and behind the excessive bolts and wire harnesses, there sits a PERFECTLY FUNCTIONAL LOCK!!!!! By this point, I'm a bit pissed. It seems I only broke the facade of the lock off, because it's plastic, 16 years old, and made by some 11 year old in China. But on the other side of the column, BEHOLD! A completely shattered plastic (surprise!) gear responsible for closing the ignition switch. Totally f**ked, I am, as O'Reilly, Auto Zone, Advance Auto Parts, Napa Auto Parts, and Bumper to Bumper Auto Parts haven't the faintest idea what the hell I'm talking about. Thus my endless quest for YouTube video's on how to hotwire a car. Today I decided what the hell and set out with wire cutters and multimeter in hand. So here it is. I was successful in hotwiring a 1994 Camaro. I know what you're thinking. "But what about the VATS (Vehicle Anti-Theft System) system?!" I came to that obstacle about two months ago when for no apparent reason, my key no longer worked and the dash flashed "Security." Well, my mother didn't raise no idiot. A couple resistors and a soldering iron later, and Chevy's best attempt at anti-theft is but a laughing matter.
