A no crank, no start fault is shown along with the multiple cause with diagnosis. - Авто та транспорт
This is a great video I had a 2009 164 do the same thing, I had an authorization issue at that time..
Hi! I have an '06 164 and its doing something similar when trying to crank the instrument cluster powers down, this happens a few times before I can actually start the car, can you tell me how you fixed it, or got it fixed? Thanks in advance!
@@samstrat01 hi, please I have same problem e klasse 220 2007, did found the problem?
@@samstrat01 same here
Good morning, I have a 2010 GL 450 , when I hook up the Phoenix Max TopDon scanner, first I get is Key in Position HO auxiliary contact NO. Also I don’t hear my ESL working. Any suggestions. I really appreciate your feedback.Thanks again.
What kind the scanner you used
I have the "no crank no start" issue (plus "no fuel pump") on my '97 C280, but only occasionally! The first start-up in the morning always works. If I stop at the fuel station 5 minutes later, just like yesterday, the car may not start again. If it happens, all the lights are on as well as the ignition, but I don't hear the fuel pump and turning the key won't do anything. I was able to get the car started yesterday by tapping on the ignition switch (the plastic cover was already removed). The EIS or some loose connection inside or on the back seems to be the culprit here, would you guys agree? Changing the key makes no difference.
What is key in HO 'aux contact'
Hi guys can u pls help me out with a trouble code of 900 E. On a benz b200 2009 model auto
Yeah thanks this circuit 50 stuff blew my mind. The picture showing purple wire helped. Never heard of circuit 50. I do however know about a starter relay. Lift is out and inside you have pins 85,86 87, 87a and 30 - Its 87 that goes directly to the starter solenoid. Lou (a guy on youtube) told me its the wire to starter. So then just say pin 87 from starter relay.
Does anyone out there have a logical reason for why they dont say that?
The term "terminal 50" or "circuit 50" is a standardized name for the starter motor activation circuit. The organisation that made the standard is called "DIN" an abbreviation in German for their standards organisation. DIN is also responsible for the numbers on the relay pins (i.e. 30, 87, 86 and 85) as well as 15 (ignition ON), 31 (Earth), etc.

Circuit 50 for me changes from off to on but the car doesn't crank. It also doesn't show P or C or S mode on the instrument cluster when the engine is off but the key is in the ON position. Sometimes the P and C or S mode will randomly show up and then the car turns on normally. When it's on it drives normally. I also sometimes randomly get ABS and ESP inoperative messages while driving, PRE-SAFE INOPERATIVE, Steering gets harder then it goes away after a few seconds of driving. HELP!! lol
Did you find a solution? My ML 2008 is doing the same thing
@sco234 Yes. I had a bunch of weird things happening to me, and it ended up being the front SAM fuse box. The previous owner had left it exposed a whole winter, and water had seeped in and corroded the whole board inside, causing a bunch of weird things. I ordered one used from eBay and changed it and all my problems were gone...
so n other word the start need replace if passenger side
How do you use a scanner that majority of people don’t have, them don’t tell us what scanner you used? Should we get this & will we regularly need the scanner
Take it to a professional...
Our shop has the latest autologic and also the legacy one..we can’t even scan for codes, key doesn’t even turn. Same car..
I remove eis and then send away to be repaired when that happens and if both keys wont make it turn. Always come back repaired. I am learning more though. They dont like cold weather. You can get a cheap donor and buy the equipment to clone an Eis yourself. Only equipment is over a thousand pounds and repair if like under £300 so if you only doing one, send it away to Eis rebuilders. Find them on EBAY.
Where can I get phone number for eis rebuilders. Please link me up
I sent mine out on ebay and key still doesn't turn
EIS - Electronic Ignition SWITCH.
Not everyone have that scanner buddy
You don't need to be here then
