Description
The MPI® detected an error while communicating with the MPEM using the DESS protocol.
Possible causes
| 1. | MPEM internal power switch is off. |
| 2. | MPEM power source failure. |
| 3. | Bad connection between the MPI and the MPEM. |
| 4. | Electrical noise on communication lines. |
| 5. | Incompatible MPI software revision. |
Suggested actions
| 1. | Remove the adapter from the vehicle DESS post, wait for few seconds and then insert the adapter again. |
