2011 Mercedes GL350 Bad EIS
2011 Mercedes GL350 Bad EIS
I've been trying to troubleshoot what could possibly be a BAD EIS and would like any feedback. Typically, in the morning at first startup, I get a "Drive to workshop without changing gears" or SRS Restraint Sys Malfunction Service Required" message. I can "resolve" this problem by removing the 7.5 amp fuse that goes to the EIS for around 30 seconds and put it back in. Most times the vehicle will start and run fine for the day. There's been two times in the last two or three weeks where I had to do it twice, after the instrument cluster threw a fit of warning messages. It appears that the CAN bus goes inactive and is not able to wake up until the EIS is power-cycled. I tried disconnecting and measured the X30/19 connectors/CAN C bus. I received 120 ohms of resistance between the CAN H to CAN L. I also measured resistance of all nodes; most for 25K or 52K ohms, except two. The ESP measured opened (It appears the ESP nod isn't energized until the EIS or other component powers it on). The Oscope showed signs of life once the key was powered on. The Steering Column module measured 126 ohms between CAN H and CAN L. Here are all of the stored codes that collect over the past 24 hours. I just replaced the engine and had to replace the bad battery (the vehicle has been sitting for around 8 months was at 8.5 volts). It's possible that part of the wiring harness could have become damaged during the transfer, but I don't think it's that. There were no electrical problems that I'm aware of when it last ran during the summer, but now it's winter.Here are the codes from the scan, along with the rollup below it (Report also attached):
