Fault Code 9A07 Component B48/14 (WSS)
Hi
I am getting below error in my XENTRY DAS Software for SRS light I am getting on my 2008 ML350 (W164). Can someone point me to right direction what I need to do.
-----------------------------------------------------------
Possible Cause1:
Right Rear (WSS) Open Circuit
Fault Code 9A07 Component B48/14
9A07 - Right Rear WSS sensor has an open Circuit in the wiring
Test:
Inspect Connector "E" at Control Module N2/13 (WSS Control Unit)
--------------------------------------------------------------
Weird thing is XENTRY system says Right Read Sensor where as message in my dashboard says Malfunction in Right Passenger Seat.
History:
My aux. battery was bad and I changed this battery, during this process (not sure where) looks like one of the wire got disconnected or came loose or something else happened. Since then my SRS light is staying on. I looked around battery compartment (Under passenger Seat) and harness under the passenger seat did not find anything loose or out.
Does anyone have wiring diagram for WSS system for W164 ?
Please help to me figure out this problem.

If that is all it was you should be able to clear it with the Star System. Clear it and see if it comes back. If it does then it's something to look at but pull codes and post.

I did reset using Star System yesterday but it came back. Looks like loose connection somewhere but not sure which one. As far as I can see all of the connections are good unless single wire lost connection within harness which I cannot see.

Retrace your steps on the removal and replacement of the aux battery. If it was a simple failure to reconnect look for a lose wire behind or under the battery. If not then you need to start tracing from the module assuming it is a lose or broken wire and not a bad module. Star say the module was good? If so then it's wiring and you need to kill power and isolate each wire from the harness to test. Good luck.

2001 ML 320 and 2010 ML 350
good evening. I have a 2010 ML 350. While driving today, my dashboard lit up like a Christmas tree with SRS restraint malfunction. I turned the car off and tried to restart it, but it would not. I had it towed to my home where I used my Autel to scan it. I got codes 919c, 9187, 9188, 9189, 918a and 918b. They all state the same thing " no CAN message is received from the control module N73 EIS/EZS control module". This happened to me last month and I replaced my battery per this and other forums suggestions. Does anyone have any other suggestions as to what else to look into?
Thank you
