Just picked up a 1998 C43 for a good price, but it's got some issues! Oil leaks, drive shaft bearing, small rust spots,and my main concern is the SRS light is on! I ran the codes and it came back 033 passenger airbag sensor no communication (A54)! Is anyone familiar with this code, that could Give me a starting point to hunt the problem down.

Thanks Jim

 

Airbag impact sensor under the carpet under the seat, looked like something spilled down there. $500 at the dealer, but I found a used one on ebay for $40 different car but same part number worked fine!

 

i have a clk320 with a srs light coming on and im not sure where to start any help is appreciated

 

You need to run the code on a code reader! Most common SRS fault is passenger seat occupancy sensor, but no way to tell until you run the code!

 

thank you so much for responding! it seems it may have been under the seat two wires were broken I reconnected and the srs light went off hasn't come back on yet! thanks again!!
