Could anyone help with a code lookup for me?

Unfortunately, I don’t have the service CD for this car (it is my elderly fathers car, and I really want to help him with this.)

Car: 1994 E420, California version

I got the following codes from the self-diagnostic system via the blinking LED on the socket. This car has 87,000 miles & has not had the wiring harness or throttle slide replaced (although from what I understand it’s inevitable). I cleared the computer codes by unhooking the battery, and then these codes came back up after driving the car for about 25 miles. CODES: 10, 16, 17, & 19.

Thanks for your help!

RTH

Code 10 = Voltage at air mass sensor incorrect.
Code 16 = Closed throttle position incorrect info.
Code 17 = Data exchange between ECU's incorrect.
Code 19 = Fuel system short term adaptation at limit.


YOU might have a "bio-degradable" engine wiring harness!

The simplest way to tell about the harness is to view the single ground wire that goes down the center middle of the intake. Most of the other wiring is securely sealed. Too bad they didn't make the wire insulation out of the same tough material as the shielding.

If you go beyond the harness there is a lot of info on the code 19 problems in the archives. One should also check the individual control units for codes (see the article in DIY section or archives for procedures). You have pulled codes from the Diagnostic Module (DM), you also need LH (fuel control), DI (ignition), EA/CC/ISC (electronic accelerator/cruise control/idle speed control) and possibly the base module (control unit UPS/power supply module)

Thumbs up Thanks guys – It’s good to “see” you both again!

I apologize for my ignorance on the idiosyncrasies of this model – once again, I find myself on the steep end of the learning curve.

I took the air filter cover off this morning, and lo & behold, the ground wire is decaying like some sort of ancient archeological artifact. So we’ll need a harness at the very least.

While I had the cover off, I discovered that the threaded portion (length adjuster) of the throttle cable housing had snapped off, so that the throttle pedal is not actuating the linkage properly. (Interesting – I figured that since this is a drive-by-wire throttle, that the gas pedal would be hooked up to nothing other than a spring & a potentiometer. Ignorance reigns supreme )

I looked at all the code 19 information in the archives – Yikes! I noticed that someone had hacked an EPROM with the new code. I hope that this may be available as an alternative.

Do either of you know what the current mind-set of Mercedes North America is regarding replacement harnesses? One dealer said that MBZ ‘might’ pay for the harness if the dealer installed it – at 7.5 hours of labor! (Maybe the mechanic is a paraplegic working with his feet ) Ideally, I would like to get the harness from MBZ & install it myself. Do you guys have any suggestion on who or where I should start with at MBZ on this issue?

Thank you so much for your help with this!

P.S.:
Steve, I looked at the article in the DIY section – a good primer for us ‘shade tree’ types! Excellent article, but then again, what else would I have expected?
