Interesting Connection Problem

**agunjal** · 02-23-2007, 09:13 PM

Hope someone can help me here. I bought my 01 - S430 last month. No check engine light but some hesitation. So I purchased a OBD II reader. I read and got some codes. Misfires, Air Mass error. No problem. Figured a tune up and new MAF would be ok. So last night my check engine light comes on. So today I decide to read to codes again. I keep getting errors. It wont read. So I try the reader on my wifes Nissan..No problem...reads everything. So why wont the OBD tool read my Benz? Is there a fuse? Any ideas?

Any help would be appreciated

Sorry agunjal I reject the basic premise of your post. It isn't interesting.

It is important to make sure that the OBD2 plug is fully located in the socket - there are two longer pins which pick up the power, and often give the impression that the tool is fully located when it isn't.

Checking this is certainly worth a try before looking at the more complicated explanations.

Good Luck!
