Update: Having no luck in identifying the blown part in location D409. Did get to actually talk to a Toyota Technical Region Rep, but no dice on the schematics or component information on the part. Apparently, this is still proprietary which "is still in Japan". Was suggested to purchase a used...

Actually, I did price out a used one, but then I would have to take (tow) the vehicle in to the dealership to reprogram the ECU for my keys (security, immobilizer, transponder) to see if it would work. But I know I have other issues (VSC & ABS - earlier in my posts) that might still prevent it...

Shot of the blown component, which I believe to be a diode, just can't make out the markings, too burnt. Anybody know what this is? It is in location D409.

Yep, I understand the slim chances but at this point what do I have to lose? A new one would cost 1k, then add in reprogramming, taxes and whatever the stealership intend to top it off with, verses 2 bucks for a diode some solder and my time. Even ECU repair services state that not all ECU can...

Finally had a chance to do some more troubleshooting. Found a blown zener diode in the ECU. Now having a hard time locating information about it and where to buy one. Anybody know of this component and where to get a few? Its in location D409 and has these markings, D.4 3G Thanks for any info...

I appreciate your thoughts and indeed it wouldn't hurt and I like the idea of playing it safe. I'll have a look see this weekend. I also did send an inquiry to my local toyota service dept and ask for suggestions and got back a response that the ignition switch or ignition lock cylinder would...

@ aeb28 Thanks for your input. I googled this component and read other forum posts. So, I went back out and tried to start with the A/T in the neutral position, no dice. I tried again jiggling the positions, moving back to Park, back to neutral, etc. All times had the same non-responsive...

@ riceandpho No, factory installed alarm, and I tried that as well anyways. I hooked up my charger, set it for starting mode and tried starting again, no go. Now the fun begins....

Last night I took the OBD port out to closely examine it and found no loose terminals, no terminals that can be pushed back when the scantool is inserted. I hooked up the battery charger and tried the scantool again. Still no link communication. The OBD port continue to give me battery voltage...

@ BOSMECH Hmmm, I thought about that after reading other posts in the forum, so I tested it out by disconnecting the battery for 15 minutes (totally), reconnected and waited for 15 minutes and then attempted to start with the secondary key (not valet) and yielded the same results. Nice thought...

Hello MrPurplePenquin! Was starting to think I wasn't going to get any responses. Well, I suppose I could have left something off, it wouldn't be the first time I'd sabotaged my own work. However, I have since gone over the wiring a few times, as I'm sort of OCD when it comes to this sort of...

No ideas anybody?? I'm going to try to direct wire the solenoid and at least see if the engine will crank. If that happens, then I'll start to really go thru the control circuitry and the ignition switch.

Update: Couldn't get the scan tool to even link up with my 4Runner. I tried several attempts at it, even from disconnecting the battery, wait 15 minutes and re-connecting and trying again. Still no link from the scan tool to my vehicle. The lights all come on, then I'm left with VSC TRAC and...

Oops, jumped part of the story (#9 & #10), here's the sequence of events.... 9a. Turned key to start/crank and measured 0v at ignition trigger to starter solenoid. 9b. Tested continuity from ignition connector to STA relay terminal #3 >> good. 9c. Bench tested STA relay @ 12v >> good with...

Need help. 2004 Limited, V6, it won't start, no cranking, no dimming of lights. Here's the story,... 1. Was running fine. 2. Took it in for full detail, including engine block clean (regret now). 3. VSC, ABS lights on about 3 weeks later. 4. Took it in to AutoZone, said I needed new wheel speed...
