1994 E500 which has its Check Engine Light on. I went to the CAN box LED light which is only for the DM module. Hit the button for 2 to 3 seconds then counted 10 blinks.
DTC 10 on Diagnostic Module pin 19. That's the only code present; DTC 10 on DM = "Voltage at mass air flow sensor too high/low"
Anyone have experience with this. Only found this relevant thread:
Car seems to be running ok otherwise. Board recommendation is that rebuild MAFs from Bosch are ok. I reset the trouble code and see if it comes back tomorrow. Starting this thread to track my progress on this issue and help others down the road.
