AEM-E001

Condition

The control modules communicate with each other in a network via a standardized serial communication interface - Controller Area Network (CAN) - to exchange information. The control modules transmit and receive information. Diagnostic trouble code (DTC) AEM-E001 is stored if the control module registers that that there is no communication or that it is distorted.

NOTE: In the event of system communication problems, it is not possible to communicate with the control module. Therefore it will only be possible to read off the fault if it is intermittent.

Substitute value

- CAN communication blocked.

Possible source

- Defective control module.

Fault symptom[s]

- Accessories connected to the control module do not function.
