B800 SRS Scan and Reset Tool

My SRS light came on for a while last week after starting the car. I bought a B800 scanner. before the scanner got to me, the SRS dash warning stopped illumination...on it's own. I scanned the SRS and a code, not to be found in the manual's lists of codes came up: Table 03, code 70. There is no code table 03. There is a code 70 (seat sensor) listed on another table and the only place 70 is listed. Also not to be found is a contact for help in any way for this tool and it's use. the manual repeatedly says there *are* errors in the manual and to refer to your BMW dealer. Is anyone on the Bimmerboard proficient with this tool and might comment on the 03 Table readout?

I suggest you toss it and buy the Peake SRS tool. I used it to find a problem with the passenger seat sensor. At least, with Peake, you have an American supplier who you can call. You've already paid more than $50 in anguish.

S800 vs. Peak SRS

I had no idea in is Chiina junk until browsing the manual. Poor quality. No customer service of any kind.

Edjack, is the Peake SRS tool manufacturer specific? For example, can I scan AC codes and other non emission related problems? Thanks

No. SRS = Supplemental Restraint System, aka air bags. It's the best low-cost BMW scan tool specifically for this task.

Get a general-purpose scan tool for reading P-codes. You'll need a BMW-specific tool to read all other codes besides engine and transmission. Good tools like this are in the $5-10k range.

There are laptop-hosted tools out there that are more comprehensive than generic $100-600 tools. Perhaps someone will chime in with their experiences.

I have my PEAK SRS scanner now

I mailed the made in CHINA tool back to Amazon and was reimbursed for all cost even postage. My SRS airbag light is still coming on sometimes and then, on it's own, going away. The Peak scanner says it is the drivers seat sensor. I cleared the code a week ago and the dash light behaves as mentioned above. It is OK most of the time even though the Peak tool still picks up the sensor code. I wonder if the airbag is functional even though the SRS bag light is off and the code can still be picked up by the scanner? Probably best to just replace the sensor on the side of the seat and check the seat belt wires, etc. I have been having seat cable issues and if the seat is pulled back too far it probably rubs the seat belt receptacle at times.

the multiple restraint system module (MRS) can go bad. It's located under the rear center console/armrest. The MRS module controls the airbag system.

had a similar problem and I bought the same chinese b800 tool, worked great pin pointed the problem and clearing it, turned out it was just an oxidated connection that was creating resistance, I cleaned it cleared the code and 6 months later the light is still off! I agree the code tables are kinda confusing but I got used to it

IMHO I honestly cant complaint about this tool it's getting the job done

I had same issue. Codes were: FA, 03, 50, 03, 61, 70, --. cannot diagnose since there is no 03 chart supplied with b800 unit. Cleared codes and light went out. went for drive, and light stayed out, so I am mostly happy anyway.

I know my light only came on because I pulled every fuse and the connector under the passenger seat while looking for high current drain troubleshooting my failed alternator. So I did not really need to know what the codes meant.

I have 2002 E39 530i

I bought this B800 from Amazon a few months ago, $26.
I posted info on bimmerforums, including the manual. RFW900k (guessing on his screen name) said it was a direct copy of the Peake SRS tool.
I've used it a few times on friends cars and it does work.
Not that I like buying stuff from China (didn't know it at the time) but $26 or $150 for the same tool just in a different package.

B800 SRS Scan and Reset Tool

The Peake tool is insanely priced for a one trick pony. Get one of the computer based diag tools like INPA, PA Soft, GT1. There is a really slick looking tool that I have not tried yet that could be promising. It's the BMW specific tool from iOBD2. The screen captures show it connecting to the modules in a BMW E90, not just the engine module like the ELM327 with TorquePro. The ELM327 with TorquePro is cool, but, it doesn't connect to SRS or ABS or ZKE, etc, etc. The BMW tool from iOBD2 looks like it does. If anyone has tried it please post a quick review. So far all I've seen is posts from BMWOEM1 who looks like a salesman for the company.

So, does that mean that the Peake SRS tool, for about $100 more, also does not include the code chart for "03" that my car seems to require? Or are the instructions that the first code ("03" in my case) signifies which chart to use, simply incorrect?

Thank you,

Edward
