Euen Burke Posted July 19, 2021 Report Share Posted July 19, 2021 BMW E36, 2 litre M52 running G4+ Storm. Config file attached. Owner ran into problems installing a new Link MXS dash and has asked me to help sort the problem. Dash powers up but there is no communication with the ECU. Initially found that he had read the B connector upside down so had the CAN connection to 7 & 8 instead of 27 & 28 however even after connecting correctly there is no communication. I tried looking at the CAN bus with a DVM/Scope but there was no sign of any signal on the bus. I am unsure if it is related but there is no 5 volts on pin 33 on the B connector but there is 5V on the A connector.

Adamw Posted July 19, 2021 Report Share Posted July 19, 2021 Pin B33 is AN Volt 5 (input), not a 5V output. For the CAN, update your firmware, the Transmit MXS stream was only added in firmware 5.6.6 and later, your ecu is on 5.6.4 which is 5 years out of date.
