I picked up an 2008 E550. It has a few codes identified with my Innova scanner. The one that has me puzzled is "9102 ASSYST PLUS is Faulty". Can anyone tell me what this is specifically? I've search the web and forums but can't seem to find a specific culprit.
If code is stored delete it. If it returns 9102 is a generic code, MB DTC 9102 - resistance value in the ignition circuit containing component R12/13 (Driver airbag ignition squib 1) is too low. Also, MBUSA bulletin may or may not be applicable (9103 resistance too high) in resolving matter. You can check connections if fine, and since SRS is not illuminated I suggest having someone do a quick test using MB diagnostics.
Thank you for the feedback. I've got to get the car smog tested before I can register it in California. Hope that wont go too badly as the EVAP isn't set. I'll run the drive cycle to see if I can get it to go. Once I have passed smog, I'll clear everything and see what comes back.
There is a little laundry list:
0089 / 0077 (stored) Throttle position sensor. I have a new pedal on the way
7266 / 5195 (Stored / MIL) ESP. Assume brake switch. I have a new switch on the way
930C (Stored / Current) knowledge base configuration incomplete. I don't know what this is.
9018 (stored) Keyless go fault. Seems to work OK.
9006 (stored) Switch N72s18 (level setting switch is defective or has been operated for longer than 25 seconds. I don't know what this is referring to.
9028 (stored) Fault with CAN communication unit A6n1 (STH or HB control module). Not sure what this is referring to.
9011 (stored) Component E1m1 (left headlamp range adjustment motor) is defective. Appears to be operating correctly now.
9102 (stored) Coding of control module ASSYST PLUS is faulty. (Innova also notes: if the service menu us properly displayed in the instrument cluster this fault can be ignored. Make me wonder if a resent was done incorrectly???
D001 (stored) The watchdog function has detected an internal hardware fault. Don't know??
912E (stored / current) Not relevant! I guess this means that the system it is checking is not available on my car?
D101 / D201 (stored). Not relevant! Same as above I guess?
9211 (stored) there is a discontinuity in the line to the component M21/2r1 (Mirror heater) or the component is defective. We are a long way off from having any freezing temps here. I'll clear and see if it comes back.
