Finally got a chance to check the car. Didn’t have a voltmeter to get readings but did get power registered on the basic tester that I have. The fuses had power The PSE still is not powering on. I have replaced the k40 and picked up multiple CCMs to see if ccm is the issue. I think the PSE problem is the root of my problems. Anyone have any ideas on getting power to it? Will the Mercedes scanner find the error of i I put it in the shop?
