I need some info on wiring and specific check procedures (such as for the EIS, SAMS, and key fob) for my 99 CLK430 and I have never seen a site that gives me all the info I really need. Most are like a Haynes manual type info.

I need some deep and intensely detailed info to diagnose an issue. (voltage measurements, other tech info, connector details)

Would purchasing an ALLDATA subscription be worth it? I also see there are several forms of ALLDATA now. Just entering it in the google search comes up with several versions of ALLDATA and I dunno which one I'd use.

 

Basically I need it to be as detailed as this http://www.mercedesmanuals.com/1998_...p270020805.htm

 

I have Alldata access at school, I'll try to make it happen.

 

I don't want to do anything illegal by borrowing copywrited material, but I'd love to know if it is worth it.

 

i use a link in the LS400 forums for general servicing needs and basic wiring diagrams (not gunna post the link, you guys dont visit the LS forums enough as it is )

for more advanced stuff i bought the OEM FSM from lexus best $$ ive ever spent (and i FINALLY have one thats specific for my 99 so i can mess with the advanced electrical goodies.)

 

My friend who owns a 2000 civic SI bought the book manual that the engineers of the car put together 3rd party. He showed me it, it has every diagram and part breakdown you could ever need. He says it's the best money he has ever spent, it was expensive though. I would recommend that anyone who is into the whole "backyard mechanic" idea should invest money into a similar book.

 

i use shopkey5 alot. i think it's better than alldata.

 

Have used both Alldata, and Shopkey5. Both are good investments.

 

There's also a competing service called Mitchell-On-Demand, which, like AllData, is widely used by independent service shops. Both, however, generally require a paid subscription service, although some auto parts stores offer a free temporary hookup while in the store as part of their customer service. I used the Mitchell service myself a couple of times at the old Trak Auto stores before they were bought out by Advance Auto parts.
